If you have calculations in a calcuation or analytic view and you use procedures, which get executed first?  Is there a best practice document that discusses order of calculation?

Hi everyone,

I was wondering if there was any way to setup sql trace directly through sql without having to go through Hana studio or modifying the config file.

Also, is there any way to restrict directly this trace to a single schema, instead of having to retrieve every table/view in this schema and add them one by one?

Thanks,

Benjamin.

Hello Guys,

Can Hana DB write back in ECC in reverse ways how it replicate from ecc to ECC Database? If yes what need to be donein ordere to achieve these ?

Please suggest

Hi,

I upgraded by AWS instance to rev 56 but after that, I am not able to create a workspace.

I have confirmed the following are correct :-

Ports 30015 and 8000 are open for inbound in the security group that is assigned to my instance.

Elastic IP is associated to my instance

SYSTEM user's password is correct

HDBSQL is working.

Version is 1.00.56.377318

REGI location is updated correctly

All the services in HANA instance is running successfully.

PFA screenshots for the same

Ping does not work.

I have also attached the exception. One thing i noticed is that the JDBC ip address is not the same as my Elastic IP address.

Can this be the reason of the problem?

Any help or guidance would be much appreciated.

Thanks,

Aashrith.

I have added the screenshots for the same in the attachement. I have changed the extension to .txt. Please change it back to .zip and unzip to view the .png images.

@ Moderators : request some leeway as I am unable to attach the screenshots to this post.

I am an intern visiting Palo Alto from SAP’s Shanghai office for a month-long project. It’s my first trip to the bay area so I am soaking up all the sun and all the excitement here. Last weekend, I found myself wanting to watch a movie. I searched the internet and found all the new releases listed on rottentomatoes and imdb but it was hard to pick one. I wanted to get a pulse of the movie before I watch it not from the critics but actual movie goers like me. Also, I wanted one which had high buzz not only in US but also in China. So I decided, why don’t I build one myself, after all I am in the heart of Silicon Valley.

I decided to pick SAP HANA One to power my app not just because I got the db & application server in the cloud but also because the platform would support sentiment analysis for English & Simplified Chinese right out-of-the-box! I used the Rotten Tomatoes API to find newly released movies and twitter & Sina Weibo APIs for sentiment for US & China respectively.

I did most of my work in the HANA Studio which is based on the eclipse IDE so very familiar for Java and other open-source developers.

Schema

First, I created a schema and full text index for all the movie metadata, including title, rating, running time, release data, synopsis, etc. Then I used the JTomato (https://github.com/geeordanoh/JTomato) to populate the table.

MOVIE: Stores movie metadata, including the title, rating, runtime, release date, etc.

Then I used Twitter4J (http://twitter4j.org) to search the movie keywords on Twitter. I found that twitter, given just the keyword, did a good job pulling all combinations of the movie name: fast and furious, fast & furious.

TWEET: Stores crawled tweets from Twitter, including ID, time, location, content, etc.

However, I ran into problems while crawling Sina Weibo because they have a strict process for usage of their API. So I decided to use Tencent Weibo instead.

TWEET_ZH: Stores crawled tweets from Tencent Weibo

Next I created a fulltext index and sentiment tables (called VoiceOfCustomer) using the following SQL. Voila! I now have sentiment analysis for all twitter and tencent weibo data!

CREATE FULLTEXT INDEX TWEET_I ON TWEET (CONTENT) CONFIGURATION 'EXTRACTION_CORE_VOICEOFCUSTOMER' ASYNC FLUSH EVERY 1 MINUTESLANGUAGE DETECTION ('EN') TEXT ANALYSIS ON;

CREATE FULLTEXT INDEX TWEET_ZH_I ON TWEET_ZH (CONTENT) CONFIGURATION 'EXTRACTION_CORE_VOICEOFCUSTOMER' ASYNC FLUSH EVERY 1 MINUTESLANGUAGE DETECTION ('ZH') TEXT ANALYSIS ON;

TWEET_I: Used to perform sentiment analysis for the table TWEET

TWEET_ZH_I: Used to perform sentiment analysis for the table TWEET_ZH

In addition to the tables in SAP HANA and the full text index to perform sentiment analysis, I also wrote stored procedures to wrap complex SQL making it easy for XS (HANA’s application server) to consume.

Architecture

The final architecture looks like this:

Rating

Now, I had to create a formula to quantify rating. I used a very simple formula for this:

Score = (# of strong positive sentiment * 5 + # of weak positive sentiment * 4 + # of neutral sentiment * 3 + # of weak negative sentiment * 2 + # of strong negative sentiment *1) / # of total sentiments

This score would be helpful to rank movies so I could easily pick the top one.

Additionally, I showed a distribution of the sentiments, positive vs. negative vs. neutral, so I could better understand how strong or weak people’s opinion was on the movie both in US & in China.

XS Application

The application should be built on XS Engine to prevent data transfer latency between the database and the web application server so users can access the website directly. The application was built in the following steps:

Step 1: Create stored procedures for rating and sentiment analysis

Currently, there are two stored procedures in the app. One is for rating and the other is for sentiment analysis:

1. Rating

We can use the following SQLs to create the type and the stored procedure:

CREATETYPE MOVIEINFO ASTABLE (

      POSTER NVARCHAR(100),

      TITLE NVARCHAR(100),

      RATING DECIMAL(5, 2),

      NUM INTEGER,

      TITLE_ZH NVARCHAR(100),

      RATING_ZH DECIMAL(5, 2),

      NUM_ZH INTEGER,

      YEARINTEGER,

      MPAA_RATING NVARCHAR(100),

      RUNTIME NVARCHAR(100),

      CRITICS_CONSENSUS NVARCHAR(2000),

      RELEASE_DATE DATE,

      SYNOPSIS NVARCHAR(2000),

      ID INTEGER

);

CREATEPROCEDURE GETMOVIEINFO(OUT RESULT MOVIEINFO) LANGUAGE SQLSCRIPT READS SQL DATA AS

BEGIN

RESULT =

SELECT A.POSTER, A.TITLE, B.RATING, B.NUM, A.TITLE_ZH, C.RATING_ZH, C.NUM_ZH, A.YEAR, A.MPAA_RATING, A.RUNTIME, A.CRITICS_CONSENSUS, A.RELEASE_DATE, A.SYNOPSIS, A.ID

FROM MOVIE A

INNERJOIN

(SELECT ID, CASESUM(NUM) WHEN 0 THEN 0 ELSETO_DECIMAL(SUM(TOTAL) / SUM(NUM), 5, 2) ENDAS RATING, SUM(NUM) AS NUM FROM

(SELECT

1. A.ID,
2. C.TA_TYPE,

COUNT(C.TA_TYPE) AS NUM,

CASE C.TA_TYPE

      WHEN'StrongPositiveSentiment'THENCOUNT(C.TA_TYPE) * 5

      WHEN'WeakPositiveSentiment'THENCOUNT(C.TA_TYPE) * 4

      WHEN'NeutralSentiment'THENCOUNT(C.TA_TYPE) * 3

      WHEN'WeakNegativeSentiment'THENCOUNT(C.TA_TYPE) * 2

      WHEN'StrongNegativeSentiment'THENCOUNT(C.TA_TYPE) * 1

ENDAS TOTAL

FROM MOVIE A

LEFTJOIN TWEET B

ON A.ID = B.MOVIEID

LEFTJOIN"$TA_TWEET_I" C

ON B.ID = C.ID AND C.TA_TYPE IN ('StrongPositiveSentiment', 'WeakPositiveSentiment', 'NeutralSentiment', 'WeakNegativeSentiment', 'StrongNegativeSentiment')

GROUPBY

1. A.ID,
2. C.TA_TYPE) A

GROUPBY ID) B ON A.ID = B.ID

INNERJOIN

(SELECT ID, CASESUM(NUM) WHEN 0 THEN 0 ELSETO_DECIMAL(SUM(TOTAL) / SUM(NUM), 5, 2) ENDAS RATING_ZH, SUM(NUM) AS NUM_ZH FROM

(SELECT

1. A.ID,
2. C.TA_TYPE,

COUNT(C.TA_TYPE) AS NUM,

CASE C.TA_TYPE

      WHEN'StrongPositiveSentiment'THENCOUNT(C.TA_TYPE) * 5

      WHEN'WeakPositiveSentiment'THENCOUNT(C.TA_TYPE) * 4

      WHEN'NeutralSentiment'THENCOUNT(C.TA_TYPE) * 3

      WHEN'WeakNegativeSentiment'THENCOUNT(C.TA_TYPE) * 2

      WHEN'StrongNegativeSentiment'THENCOUNT(C.TA_TYPE) * 1

ENDAS TOTAL

FROM MOVIE A

LEFTJOIN TWEET_ZH B

ON A.ID = B.MOVIEID

LEFTJOIN"$TA_TWEET_ZH_I" C

ON B.ID = C.ID AND C.TA_TYPE IN ('StrongPositiveSentiment', 'WeakPositiveSentiment', 'NeutralSentiment', 'WeakNegativeSentiment', 'StrongNegativeSentiment')

GROUPBY

1. A.ID,
2. C.TA_TYPE) A

GROUPBY ID) C ON A.ID = C.ID

ORDERBY B.RATING DESC

;

END;

After creating the type and the stored procedure successfully, we can use the following SQL to test:

CALL GETMOVIEINFO(?);

From the column “RATING” and “RATING_ZH”, we can show the score on the main page.

2. Sentiment analysis

We can use the following SQLs to create the type and the stored procedure:

CREATETYPE SENTIMENT ASTABLE (SENTIMENT NVARCHAR(100), NUM INTEGER);

CREATEPROCEDURE GETSENTIMENT(IN ID INTEGER, IN LANG VARCHAR(2), OUT RESULT SENTIMENT) LANGUAGE SQLSCRIPT READS SQL DATA AS

BEGIN

      IF LANG = 'EN'THEN

      RESULT = SELECT'Strong Positive'AS SENTIMENT, COUNT(*) AS NUM FROM"$TA_TWEET_I" A

            INNERJOIN (SELECT ID FROM TWEET WHERE MOVIEID = :ID) B

            ON A.ID = B.ID

            WHERE A.TA_TYPE = 'StrongPositiveSentiment'

            UNIONALL

            SELECT'Weak Positive'AS SENTIMENT, COUNT(*) AS NUM FROM"$TA_TWEET_I" A

            INNERJOIN (SELECT ID FROM TWEET WHERE MOVIEID = :ID) B

            ON A.ID = B.ID

            WHERE A.TA_TYPE = 'WeakPositiveSentiment'

            UNIONALL

            SELECT'Neutral'AS SENTIMENT, COUNT(*) AS NUM FROM"$TA_TWEET_I" A

            INNERJOIN (SELECT ID FROM TWEET WHERE MOVIEID = :ID) B

            ON A.ID = B.ID

            WHERE A.TA_TYPE = 'NeutralSentiment'

            UNIONALL

            SELECT'Weak Negative'AS SENTIMENT, COUNT(*) AS NUM FROM"$TA_TWEET_I" A

            INNERJOIN (SELECT ID FROM TWEET WHERE MOVIEID = :ID) B

            ON A.ID = B.ID

            WHERE A.TA_TYPE = 'WeakNegativeSentiment'

            UNIONALL

            SELECT'Strong Negative'AS SENTIMENT, COUNT(*) AS NUM FROM"$TA_TWEET_I" A

            INNERJOIN (SELECT ID FROM TWEET WHERE MOVIEID = :ID) B

            ON A.ID = B.ID

            WHERE A.TA_TYPE = 'StrongNegativeSentiment';

      ELSEIF LANG = 'ZH'THEN

      RESULT = SELECT'很好'AS SENTIMENT, COUNT(*) AS NUM FROM"$TA_TWEET_ZH_I" A

            INNERJOIN (SELECT ID FROM TWEET_ZH WHERE MOVIEID = :ID) B

            ON A.ID = B.ID

            WHERE A.TA_TYPE = 'StrongPositiveSentiment'

            UNIONALL

            SELECT'好'AS SENTIMENT, COUNT(*) AS NUM FROM"$TA_TWEET_ZH_I" A

            INNERJOIN (SELECT ID FROM TWEET_ZH WHERE MOVIEID = :ID) B

            ON A.ID = B.ID

            WHERE A.TA_TYPE = 'WeakPositiveSentiment'

            UNIONALL

            SELECT'一般'AS SENTIMENT, COUNT(*) AS NUM FROM"$TA_TWEET_ZH_I" A

            INNERJOIN (SELECT ID FROM TWEET_ZH WHERE MOVIEID = :ID) B

            ON A.ID = B.ID

            WHERE A.TA_TYPE = 'NeutralSentiment'

            UNIONALL

            SELECT'差'AS SENTIMENT, COUNT(*) AS NUM FROM"$TA_TWEET_ZH_I" A

            INNERJOIN (SELECT ID FROM TWEET_ZH WHERE MOVIEID = :ID) B

            ON A.ID = B.ID

            WHERE A.TA_TYPE = 'WeakNegativeSentiment'

            UNIONALL

            SELECT'很差'AS SENTIMENT, COUNT(*) AS NUM FROM"$TA_TWEET_ZH_I" A

            INNERJOIN (SELECT ID FROM TWEET_ZH WHERE MOVIEID = :ID) B

            ON A.ID = B.ID

            WHERE A.TA_TYPE = 'StrongNegativeSentiment';

      ENDIF;

END;

After creating the type and the stored procedure successfully, we can use the following SQLs to test:

CALL GETSENTIMENT(771313125, 'EN', ?);

CALL GETSENTIMENT(771313125, 'ZH', ?);

Step 2: Build the application based on XS Engine

Till now, we can access the tables, indexes, data and stored procedures directly from the XS Engine. To build the application, follow the following steps:

1. Create .xsaccess, .xsapp and .xsprivileges to do the access control.

2. Create getMovies.xsjs to call the stored procedure “GETMOVIEINFO”

function createEntry(rs) {

      return {

            "poster" : rs.getNString(1),

            "title" : rs.getNString(2),

            "rating": rs.getDecimal(3),

            "num": rs.getInteger(4),

            "title_zh" : rs.getNString(5),

            "rating_zh": rs.getDecimal(6),

            "num_zh": rs.getInteger(7),

            "year": rs.getInteger(8),

            "mpaa_rating": rs.getNString(9),

            "runtime": rs.getNString(10),

            "critics_consensus": rs.getNString(11),

            "release_date": rs.getDate(12),

            "synopsis": rs.getNString(13),

            "id": rs.getInteger(14)

      };

}

try {

      var body = '';

      var list = [];

      var query = "{CALL SMARTAPP.GETMOVIEINFO(?)}";

      $.trace.debug(query);

      var conn = $.db.getConnection();

      var pcall = conn.prepareCall(query);

      pcall.execute();

      var rs = pcall.getResultSet();

      while (rs.next()) {

            list.push(createEntry(rs));

      }

      rs.close();

      pcall.close();

      conn.close();

      body = JSON.stringify({

            "entries" : list

      });

      $.response.contentType = 'application/json; charset=UTF-8';

      $.response.setBody(body);

      $.response.status = $.net.http.OK;

} catch (e) {

      $.response.status = $.net.http.INTERNAL_SERVER_ERROR;

      $.response.setBody(e.message);

}

3. Create getSentiment.xsjs to call the stored procedure “GETSENTIMENT”

function createEntry(rs) {

      return {

            "sentiment" : rs.getString(1),

            "num" : rs.getInteger(2)

      };

}

try {

      var id = parseInt($.request.parameters.get("id"));

      var lang = $.request.parameters.get("lang");

      var body = '';

      var list = [];

      var query = "{CALL SMARTAPP.GETSENTIMENT(?, ?, ?)}";

      $.trace.debug(query);

      var conn = $.db.getConnection();

      var pcall = conn.prepareCall(query);

      pcall.setInteger(1, id);

      pcall.setString(2, lang);

      pcall.execute();

      var rs = pcall.getResultSet();

      while (rs.next()) {

            list.push(createEntry(rs));

      }

      rs.close();

      pcall.close();

      conn.close();

      body = JSON.stringify({

            "entries" : list

      });

      $.response.contentType = 'application/json; charset=UTF-8';

      $.response.setBody(body);

      $.response.status = $.net.http.OK;

} catch (e) {

      $.response.status = $.net.http.INTERNAL_SERVER_ERROR;

      $.response.setBody(e.message);

}

4. Create index.html and code the HTML part.

<!DOCTYPEHTML>

<html>

      <head>

            <metahttp-equiv="X-UA-Compatible"content="IE=edge">

            <title>Real-Time Movie Rating</title>

            <scriptsrc="/sap/ui5/1/resources/sap-ui-core.js"

                        id="sap-ui-bootstrap"

                        data-sap-ui-libs="sap.ui.commons,sap.ui.ux3,sap.viz"

                        data-sap-ui-theme="sap_goldreflection">

            </script>

            <!-- add sap.ui.table,sap.ui.ux3 and/or other libraries to 'data-sap-ui-libs' if required -->

            <script>

                        sap.ui.localResources("movieui");

                        var view = sap.ui.view({id:"idMovieMatrix1", viewName:"movieui.MovieMatrix", type:sap.ui.core.mvc.ViewType.JS});

                        view.placeAt("content");

            </script>

      </head>

      <bodyclass="sapUiBody"role="application">

            <h1>Real-Time Movie Rating</h1>

            <divid="content"></div>

      </body>

</html>

5. Create some views and controllers to use native SAP UI 5 to accelerate building the application.

Website

The live webapp is available at (http://107.20.137.184:8000/workshop/sessionx/00/ui/MovieUI/WebContent/index.html) but I bring down the AWS instance to reduce the billing cost. I have captured screenshots and a brief video if you find the server is down.

Real-time movie rating homepage

The following screenshot is the app’s main page. For each movie, there are two scores: the upper score is from Twitter and the lower score from Tencent Weibo.

I heard a lot of buzz about “Man of Steel” but it is currently ranked No. 7 so I was really curious. “Man of Steel” had a 3.72 rating but “20 Feet from Stardom” had a 4.54 rating. Interesting! Looking closer I discovered that this was because “20 Feet” had only 351 mentions but “Man of Steel” had more than 20K, meaning that a popular movie may not necessarily be the one with the highest score but could also be one which has the most buzz.         

I then created a page with detailed breakdown of the sentiments of the Movie’s sentiments for both Twitter and Tencent Weibo. Looks like “Man of Steel” has a higher positive sentiment in China compared to the US. Well not surprising, we like superhero movies and Superman is our favorite.

Let's see what the score on Rotten Tomatoes looks like. The critics have given it a meager 56% but 82% of the audience liked it. That number is compares well with 70% positive sentiment rating from my real-time rating app. 

"20 Feet from stardom" has 97% rating from critics and 100% from the audience on rottentomatoes. So my real-time rating app was able to successfully identify this hit from social sentiment on twitter. Looks like the movie is a sleeper hit!

This application is just a prototype now and I hope to make more enhancements to the drill-down page. For the next version, I want to use the predictive libraries in SAP HANA to create a recommendation engine for movie based on a user’s interests, something like a “Pandora for movies”. Hope you enjoyed reading my blog.

Hi all,

I was in the HANA Cerfication last week and I finished with some doubts in some questions.

Which of the following can you set up to enable the extraction of data
from SAP Business Warehouse (BW) into SAP HANA? (Choose three)
A. SAP System Landscape Directory (SLD)
B. SAP BusinessObjects Data Services
C. SAP Landscape Transformation (SLT)
D. Open hub
E. SAP HANA Direct Extractor Connection (DXC)

My answer was B,D,E.

How can you restrict SAP HANA modeling users from viewing sensitive data?
A. Use scrambled source data.
B. Remove SAP_DATA_ADMIN in the SQL privileges for the modeling users.
C. Use the pre-delivered MODELER role.
D. Remove ALTER SYSTEM in the system privileges for the modeling users.

My answer was A.

You created a model on a table XYZ.PRODUCTS. You successfully activated
the model. When you run the data preview you receive an error message
"Insufficient privilege. Not authorized". Which of the following 4
statements do you execute to resolve the error before you reactivate the model?
A. GRANT SELECT on SCHEMA XYZ to _SYS_REPO
B. GRANT SELECT on PRODUCTS to _SYS_REPO WITH GRANT OPTION
C. GRANT SELECT on SCHEMA XYZ to _SYS_BIC WITH GRANT OPTION
D. GRANT SELECT on PRODUCTS to _SYS_BIC

My answer was B.

Could you help to solve my doubts?

Thanks in advance,

Dear All

Like to share a problem.

Created Query with the table combination of VBAK, VBAP and MBEW.

When executing the report, an order for single line item is showing 2 line items in report or some time three line items,

Your help will be highly appreciated

If you are getting error message(s) with the HANA Studio (on Cloudshare desktop image) to the HANA DB after you enter the correct username or password:

a. "Error when connecting to system":

b. "Invalid Username or Password":

The issue seems to be caused by a corrupted secure storage file.

As a workaround, please follow the following steps:

1. Delete your HANA connection on the Navigator tab in HANA Studio, and then close the HANA Studio.

2. Open windows explorer, and navigate to C:\Users\Administrator folder on your Cloudshare desktop.

3. Find the folder ".eclipse" and rename it to "OLD.eclipse":

4. Open your HANA Studio and set your HANA DB Connection again. You will be prompted to set the password reminder for secure storage file. You can choose "No".

5. After that, the new ".eclipse" folder and the new secure storage file will be recreated.

6. Close and re-open your HANA Studio, to verify that the workaround fixed the connection issue.

Hi,

How can I access old announcement? Couple of days back there was announcement about "Upgrading HANA server from revision 48 to 56 on AWS" and it had a link to very informative blog. Now I can not find it.

Thanks,

We changed the hostname on the AWS Hana instance from hanaserver to something else and got this error later:

We changed the hostname back to resolve the issue. If it possible to change the hostname? It doesn't seem to make sense if we have multiple Hana instances and they all have the same hostname.

Thanks!

Hello,

I am new to SAP HANA, Just learning.

Today i got a task in which i have to find a specific term in the DB. But for this i have to search all tables .

So can anyone please help me in that?

Just imagine my Schema name is 'KHAN' and i want to search 'skin cancer' in that. I have details about this in two tables so how to get this from passing a single query???

Help me please !!!

Hi Everyone,

In the blog SAP HANA Extended Application Services( http://scn.sap.com/community/developer-center/hana/blog/2012/11/29/sap-hana-extended-application-services) by Thomas Jung, he showed us lots of things about XS development and one of them was how to create and extend Server Side JavaScript and it was explained beautifully in the video :

http://www.youtube.com/watch?v=ckw_bhagvdU

At the end in the above video, Thomas told us about Calling the XSJS Service From the User Interface :

Here i would like to tell how to create the UI files and then call xsjs service step by step

1. We will go to Project Explorer tab in SAP HANA Development perspective and then R-Click and select Other:

2. Select SAP UI5 Application Development and then select Application Project:

3. We will enter project name and select Desktop for rendering the ui on our desktop and also select create an initial view so that wizard creates a view for us

4. Enter the name of the View that we need to create Select JavaScript rendering for our purpose

5. We found that wizard created three objects for us:

index.html

XSUI.controller.js

XSUI.view.js

In index.html file we will enter the full path of Source as

src="/sap/ui5/1/resources/sap-ui-core.js"

6. After that enter the following code in XSUI.controller.js file :

sap.ui.controller("xsui.XSUI", {          onLiveChangeV1: function(oEvent,oVal2){                    var aUrl = '../../../Services/Func.xsjs?cmd=multiply'+'&num1='+escape(oEvent.getParameters().liveValue)+'&num2='+escape(oVal2.getValue());                    jQuery.ajax({                              url: aUrl,                              method: 'GET',                              dataType: 'json',                              success: this.onCompleteMultiply,                              error: this.onErrorCall });          },          onLiveChangeV2: function(oEvent,oVal1){                    var aUrl = '../../../services/Func.xsjs?cmd=multiply'+'&num1='+escape(oVal1.getValue())+'&num2='+escape(oEvent.getParameters().liveValue);                    jQuery.ajax({                              url: aUrl,                              method: 'GET',                              dataType: 'json',                              success: this.onCompleteMultiply,                              error: this.onErrorCall });          },          onCompleteMultiply: function(myTxt){                    var oResult = sap.ui.getCore().byId("result");                     if(myTxt==undefined){ oResult.setText(0); }                     else{                       jQuery.sap.require("sap.ui.core.format.NumberFormat");                       var oNumberFormat = sap.ui.core.format.NumberFormat.getIntegerInstance({                          maxFractionDigits: 12,                          minFractionDigits: 0,                          groupingEnabled: true });                       oResult.setText(oNumberFormat.format(myTxt)); }          },          onErrorCall: function(jqXHR, textStatus, errorThrown){                     sap.ui.commons.MessageBox.show(jqXHR.responseText,                                          "ERROR",                                         "Service Call Error" );                     return;           }
});

7. After that enter the following code in XSUI.view.js file

sap.ui.jsview("xsui.XSUI", {      getControllerName : function() {         return "xsui.XSUI";      },      createContent : function(oController) {                var multiplyPanel = new sap.ui.commons.Panel().setText("XS Service Test - Multiplication");                multiplyPanel.setAreaDesign(sap.ui.commons.enums.AreaDesign.Fill);                multiplyPanel.setBorderDesign(sap.ui.commons.enums.BorderDesign.Box);                  var layoutNew = new sap.ui.commons.layout.MatrixLayout({width:"auto"});                multiplyPanel.addContent(layoutNew);                var oVal1 = new sap.ui.commons.TextField("val1",{tooltip: "Value #1", editable:true});                var oVal2 = new sap.ui.commons.TextField("val2",{tooltip: "Value #2", editable:true});                var oResult = new sap.ui.commons.TextView("result",{tooltip: "Results"});                var oEqual = new sap.ui.commons.TextView("equal",{tooltip: "Equals", text: " = "});                                var oMult = new sap.ui.commons.TextView("mult",{tooltip: "Multiply by", text: " * "});                 //Attach a controller event handler to Value 1 Input Field                      oVal1.attachEvent("liveChange", function(oEvent){                            oController.onLiveChangeV1(oEvent,oVal2); });                  //Attach a controller event handler to Value 2 Input Field                      oVal2.attachEvent("liveChange", function(oEvent){                            oController.onLiveChangeV2(oEvent,oVal1); });                              layoutNew.createRow(oVal1, oMult, oVal2, oEqual, oResult );                   return multiplyPanel;      }


});

8. Now we will save all the files and share the project

9. Now Select SAP HANA Repository:

10. Inside the repository select the folder where you would like to share it : I selected UI5 folder here

11. Now we will commit and activate our UI5 project :

12. As we share our XSUI project in UI5 folder in the repository, so now we can see that in our project explorer also :

13. Now in Services folder we will create Func.xsjs file that we have used in our Controller and View in XSUI project.

14. Now enter the following code in Func.xsjs file :

function performMultiply() 
{          var body = '';         var num1 = $.request.getParameter('num1');          var num2 = $.request.getParameter('num2');          var answer;          answer = num1*num2;          body = answer.toString();          $.response.addBody(body);          $.response.setReturnCode($.net.http.OK);
}


var aCmd = $.getParameter('cmd');
switch(aCmd)
{
          case "Multiply": performMultiply();          break;          default:                     $.response.setReturnCode($.net.http.INTERNAL_SERVER_ERROR);                    $.response.addBody("Invalid Choice" +aCmd);
}

15. In the browser enter address :  http://ipaddress:8000/path/index.html

As in the aboveexample we have used JavaScript, JSON, Ajax and JQuery, so i would also like to tell you some basics about them

First i will start with JavaScript

JavaScript is a Object based Scripting language. It is not a Object Oriented language.

• Client-side JavaScript allows an application to place elements on an HTML form and respond to user events such as mouse clicks, form input, and page navigation.

• Server-side JavaScript allows an application to communicate with a relational database, provide continuity of information from one invocation to another of the application, or perform file manipulations on a server.

Features:

JavaScript is very light language

JavaScript supports only supports data type but doesn't support variable type.

For Example:

In Java or C++, if we define a variable of integer type we will define it as :

int a; // so 'a' cannot hold anything other than integer

But in case of JavaScript, we only define:

var a; // here 'a' can be a string an integer or anything else
a = hello; // 'a' becomes string
a = '10'; // here 'a' becomes an integer

JavaScript doesn't have Keywords like Class, Private, Public but there are different ways through which we can make an object Public or Private and we can even use Inheritance concept in JavaScript through the use of prototype and inherit from.

To learn more about JavaScript, please visit http://www.w3schools.com/js/ or http://www.javascriptkit.com/

SAP HANA has JavaScript editor that includes the JSLint open-source library, which helps to validate JavaScript code.

For debugging purpose:

We can use SPA HANA debug perspective or any browser like Chrome and Mozilla Firefox.

Chrome has default JavaScript debugger and for Mozilla, we can download a plugin called Firebug.

There is also a free online tool called jsfiddle that can be used to create, debug and run your JavaScript code along with HTML and CSS.

jsfiddle : http://jsfiddle.net/

Now moving on to JQuery :

JQuery is a JavaScript Library and it simplifies our JavaScript Coding as we don't need to write many lengthy codes.

In the OPenSAP course in Week 4 Unit 3 example a JQuery function fadeout() was used on Button.

To learn more about JQuery, visit http://www.w3schools.com/jquery/ or http://learn.jquery.com/

Now about JSON :

Well JSON stands for JavaScript Object Notation.

It is a light weight data interchange format and it is preferred over XML because:

In XML, Parsing is difficult and XML doesn't support rich data type( everything is written in the form of string )

Other benefits of JSON are that :

Data is typeless and values can be assigned dynamically.

Its Syntax is written in key and value pair

For Example => User(Key) : Name(Value)

We can use eval  and JSON.parse functions to convert JSON String into JavaScript string.

JSON.parse is preferref over eval because of the following reason :

When we use eval to parse JSON data, eval is always active and it might be used to create malicious data that can be harmful to our sources.

For learning JSON visit : http://www.w3schools.com/json/default.asp

Finally AJAX :

AJAX stands for Ashynchronous JavaScript and XML

It is one of the Web 2.0 standards and is used by web applications to send data to and retrieve  data from a server asynchrously without interfering in the display and beahaviour of the existing page.

It runs completely independent of the browser and no plugins are required.

Google Suggest was the very first example of using AJAX.

In most of the payment sites we generally see " Please Wait! Your Order is being processed" - this is done through the help of AJAX only.

One of the sites from where we can download those moving GIFs for our web design is : http://ajaxload.info/

For learning AJAX visit : http://www.w3schools.com/ajax/

Thank You for reading the Blog.

As this is my very first Blog so i would like to get feedback

Hi,

I just followed the steps to configure the SAP HANA Studio.

However, the folders in the SAP HANA Repository are different from the one shown in the tutorial video. Week 1 Unit 5.

Please help me resolve this issue

Hi,

i need some help with the input parameters of an OData service. I'm trying to consume a calculation view via a OData service which has three parameters.

- P_DATEFROM (Date)

- P_DATETO   (Date)

- P_REGION (String)

I used a similiar definition like here: http://scn.sap.com/community/developer-center/hana/blog/2013/01/22/rest-your-models-on-sap-hana-xs

The definition of the service works fine, but if i try to open it with some parameters i receive an error:

http://server:port/path/service.xsodata/InputParams(P_DATEFROM='2012-01-11',P_DATETO='2012-01-15',P_REGION='BIN')/Results?$select=NAME,REGION

=> Illegal query syntax.

I'm not sure what is wrong, but i think the date format is not 100% right and i can't figure out what.

Thanks and best regards.

Manu

Hi folks,

I was following the upgrade guide from Juergen Schneider but I am getting this user/password error.

I changed already the password of the root user and I also changed already the password of the dbuser SYSTEM.

I am a bit lost here, anyone any idea what I can do?

Thanks+Regards, Thomas
