Hi All,

I have around 7 years of experience in QA, which involves BI reports and Functional testing with little bit knowledge on SQL and ETL testing.

Off late have heard about HANA as trendsetting tool in the area of DWH. I would like to transform my career to SAP HANA but i don't know in which are of SAP HANA i need to continue and for that start learning. As per my understanding one from QA can get in to Functional Consultant profile, but is there any other options in this regard?

Appreciate your time and input. You also share your advice and any documents on jprakash.bdvt@gmail.com

Hello, I am trying to grant select access to myself to a schema that I have just created with the following command from developer guide:

call

_SYS_REPO.GRANT_SCHEMA_PRIVILEGE_ON_ACTIVATED_CONTENT('select','<schema name>','<user name>;

and I encountered the following error:

"insufficient privilege: Not authorized'

I think I need admin access to run the above command, is that correct? Can someone help me this resolve the error please?

Thanks in advance,

Suresh.

Want your own SAP HANA Server?

SAP has joined forces with several cloud providers to give you a choice of infrastructure platforms. Below you find a rough overview of your choices, explore the vendors websites to find out more about their offerings.

And what about SAP HANA One?

You may have heard of SAP HANA One, a cloud-based SAP HANA Database that is sold via AWS Marketplace. So how is this different from these offerings? And which [HANA] do you want??

Well, the main difference is in the license - the developer edition offered here only allows you to develop, test and demo HANA applications. You don't get the right to use those applications productively on the developer edition or sell the apps as a cloud-based service. For that, you need to move to HANA One (contact us at inmemorydevcenter@sap.com if you need help with the migration). HANA One removes the limitation of "dev only" and allows you to use your HANA application in production. There is also an OEM program, if you want to sell HANA One Applications to your customers. On the other hand, if you are not ready for production use and just exploring HANA or developing a HANA app, then you would be wasting money on HANA One. Check out this comparison between SAP HANA One Business Edition and the developer edition offered here.

Your Choices

Here is what you get:

• A free perpetual license to build, test and demo applications that use SAP HANA
• An cloud-based server environment with SAP HANA DB pre-installed - you know that SAP HANA is
  sold as an appliance, and this is sort of a "virtual appliance".
  Bear in mind that although the developer license is free of charge, the
  server is not - the cloud providers will charge you for their hosting service.
• SAP HANA Studio, developer edition for download - the SAP HANA Administration
  and Modeling tool
• SAP HANA Client, developer edition for download - SDK's for JDBC, ODBC, ODBO
  and Python DB API, so you can build client applications.
• You can also get a free 30-day trial of SAP Visual Intelligence - hook it up to your
  personal SAP HANA instance and explore your data in real-time.

I can't find a way to convert an IF exists from microsoft sql to hana.

With mssql, IF can be used to execute a sql command only if the condition is true.

Someone have an idea on how to do this ?

code:

if not exists(  select * from SYS.TABLE_COLUMNS where Schema_Name = CURRENT_SCHEMA AND TABLE_NAME = 'TableName' AND COLUMN_NAME = 'Column'      )

alter table TableName

Hi, due to the performance issues we are facing, we try to investigate the query plan.

We found some description how to generate it in admin guide, however it is not sufficient in a sense that it only refers how to generate but not interpretation which information means what.

What is worse, we now cannot generate it on rev. 52 which used to work on rev. 47.

Please someone kindly advise how to resolve the issues above.

Hi all.

I wants to know about jdbc client info API.

I have to use different query as jdbc version.

For example

if Client version is 39 and then execute Another query that right for Revision 39.

if Cient version is 51 and then execute Another query that right for Revision 51.

I think con.getMetaData() is not enough.

do you have any idea about this?

please give me advice.

thanks.

Introduction

The integration of SAP HANA with SalesForce.com (SFDC) will provide an unique solution that will harness the user experience of SFDC with real time analysis of data using SAP HANA. In this blog we explain the POC developed using SalesForce adapter provided by SAP Business Object Data Services (BODS) to extract information from SalesForce.com, normalizing and storing the data in SAP HANA and expose processed data via SAP HANA Extended Application Services Server (XS Server).

Business Value 

Statistical analysis of the customer data will help business pinpoint the inconsistencies and take corrective action. It will also help track customer behavior; identify trends and potential business opportunities. SAP HANA provides statistical functions as part of Predictive Analysis Library (PAL). These statistical functions can be used to analyze customer data from SFDC and develop a statistical control process to support client’s business objective.

Steps to integrate SAP HANA with SalesForce.com

In addition to the data analysis the other steps that go into building this solution are:

1. i. Importing data from SFDC into SAP HANA
2. ii. Storing the data in a normalized way in HANA database
3. iii. Exposing the analyzed data for consumption by other applications

There are multiple options available to import data from SFDC into SAP, in this blog we focus on SalesForce adapter provided by SAP BODS as –

• Data can be formatted as required in HANA Database in BODS.
• Browse SFDC metadata from the BODS Designer
• Set up a fully automated process for SFDC integration
• The solution developed will take relatively less development effort

SAP HANA XS Server provides the 3 options for web clients to consume data –

• ODatawebservice  
• XML for Analysis (XMLA) webservice 
• Web based UI developed using SAPUI5.

The diagram below shows the components and dataflow for HANA to SalesForce integration.

Importing data using BODS Sales Force Adapter

To use the Adapter for Salesforce.com from SAP BusinessObjects Data Services please follow the following steps.

1. Install SAP BusinessObjects Data Services version 12.0.0 or later. The Salesforce.com adapter is installed automatically with this version.
2. Configure the Job Server local for adapter management.
3. Configure the SAP BusinessObjects Data Services Adapter for Salesforce.com interface.
4. Create adapter datastore
5. Import metadata from SalesForce
6. Use imported metadata to create dataflow

Develop ODataWebService using HANA Extentded Application Service

OData is a resource-based Web protocol for querying and updating data that maps the persistence model to consumption models. An OData application running in SAP HANA XS can be used to provide the consumption model for client applications exchanging OData queries with the SAP HANA database.

OData enables clients to consume authorized data stored in the SAP HANA database. OData defines operations on resources using RESTful HTTP commands (for example, GET, PUT, POST, and DELETE). Data is transferred over HTTP using either the Atom (XML) or the JSON (JavaScript) format.

Given below are steps to create an ODATA Webservice for HANA XS Engine:

1. Create analytical view or calculation view to be exposed as ODATA Web Service - Using Modeling perspective created Analytical view AN_ORDERS in package xsandas3.

2.     Create a XS Project-  A new XS Project – xs_order_prj created using Development Perspective.

3.     Set up ODATA Service files - Application descriptor (.xsapp) and application access (.xsaccess) files created.

          Application descriptor (.xsapp) is a blank file.

a) Right click on project created and use New -> File option to create .xsapp, .xsaccess and order.xsodata files.

b) Application access (.xsaccess) file is created as shown below. This file is used define what is to be exposed as web service and who has access.

c) Create file order.xsodata to expose the analytical view – AN_ORDERS as a web service. The ODATA Service is defined as –

service {

       "xsandas3/AN_ORDERS.analyticview" as "orders1" keys generate local "GID" aggregates always;

}

4.          Commit and activate service– Commit and activate the .xsapp, .xsaccess and order.xsodata file.

After the files are committed and activated successfully the orange bubble icon appears

5.     Testing  Odata Services  - ODatawebservices provide multiple parameters and syntax to support multiple operation such as retrieving the metadata definition, apply filter, selecting a subset of record.

ODATA URL: The ODATA URL is based on the server name, instance number of the HANA system, package name, xsodata filename and entity set name.

The actual server name, instance number, package and xsodata filename can be replaced in the URL -  http://<servername>:80<instance number>/<package>/<xsodata filename> to determine the URL string. 

The below table provides sample URLs and output assuming server name is acmecorp.com, instance number is 00, package – xsandas3,  xsodata filename is order.xsodata and entity set name = orders1    . 

Building SOAP based web service using XMLA

XMLA enables the exchange of analytical data between a client application and a multi-dimensional data provider working over the Web, using  SOAP based web service. Implementing XMLA in SAP HANA enables third-party reporting tools that are connected to the SAP HANA database to communicate directly with the MDX interface.  I will provide details regarding building a XMLA service in next edition of my blog.

Accessing Webservice in SalesForce.com

Salesforce.com provides APIs that support both SOAP and REST based webservice. The Webservices defined in HANA can easily be accessed and consumed.

Hi,

Sometimes I see a table under two different schemas (SYS and PUBLIC).

I checked both and their content appears to be same and same record count.

My question is SYS vs PUBLIC. Most of the time a table exists in both schema.

Why is it like this?

Can anybody please explain?

Regards,

SS

Hi Gurus,

I am trying to work with windows function in SAP HANA

I am using below query to partition data over a dimension

select class, val, offset,

  ROW_NUMBER() OVER  (partition by class order by val) as "row_num"

from T;

I am getting below error

Could not execute 'select class, val, offset, ROW_NUMBER() OVER (partition by class order by val) as "row_num" from ...' in 19 ms 136 µs . SAP DBTech JDBC: [257] (at 49): sql syntax error: incorrect syntax near "(": line 2 col 22 (at pos 49)

Table T is created using example for SQL reference manual

Please advice

Thanks,

Hello Experts,

I have made the following observation and I wonder if I'm missing something or if there is a limitation in the way string columns can be combined as Calculated Columns within Analytic Views.

I created an analytic view solely with the aid of the visual editor. All columns used in the view are defined as string data types of which the row count is used on one of them to define it as a measure column. This works fine as I get the expected results from the view. Now if I create a calculated column by combining two columns (neither is the one I use as a measure) using the + operator, the validation fails with the error that the data type of measure column has to be numeric. This was acceptable previously but now that I have introduced a concatenated column (of two string columns), I get a failure on the validation step. Here is a snippet of the error:

Error Message

Internal deployment of object failed;Repository: Encountered an error in repository runtime extension;Internal Error:Create Scenario: failed aCalcEngine.createScenario(): The following errors occured: Inconsistent calculation model (34011)nDetails (Errors):n- CalculationNode (dataSource) -> attributes -> attribute (COUNTER): Keyfigure has to be numeric.n- CalculationNode (finalAggregation) -> attributes -> attribute (COUNTER): Keyfigure has to be numeric

So I removed the column I used as a measure and introduced a measure column from the base table which is defined as a numeric column and bingo the view works with concatenated columns as expected. I then re-introduced the previous column as a second measure and the validation step fails again with the same error.

From this it appears that you must have only numeric measure columns from the base table for you to create any concatenated string column (as a Calculated Column). Since this is fairly straight forward to implement in a raw sql, I think this is perhaps an issue with the studio unless I have missed a step somewhere.

(Searching thro the various posts, I am led to believe that I can indeed use the + operator for concat operation on string columns).

I'm on CloudShare with:

SAP HANA Studio

Version: 1.0.48

Build id: 201301130825 (372847)

HDB version info:

version: 1.00.48.372797

Any thoughts?

Hi,

I was reading the HANA documents regarding backup and restore and have some questions. Please assist

1.Where does the log files for commited transactions get stored

2. Is the files which i see on /sap/mnt0001/log the online logs

3. Is the files in /usr/sap/<SID>/HDB00/backup/log created only when performing a backup or  it is created when a transaction is commited.

When using a SAP HANA DB, is there any differences of the query structure design, to take advantage of the performance gains?

Is there any aspects that you should consider when designing new queries?
