HANA Changing the type of a column

Hi All,

Can we change the data type of a column using any function in HANA using a calculated column...

There is a function called Date() which changes a date type of a field which is loaded from SLT into HANA(The fields loaded from SLT are by default given type as Nvarchar), but this function does not change the type of the field.

Is there a way to change the type of a field.

Thanks,

Sneha
