HANA Changing the type of a column

Do you mean to alter the type in the table?

If so, you could use the ALTER command, check the alter_column_clause:

http://help.sap.com/hana/html/sql_alter_table.html#alter_table_alter_column_clause

CREATE TABLE t (a INT, b INT);ALTER TABLE t ALTER (b INT DEFAULT 10);

If, alternatively, you mean to change the type just in the view, then you can achieve that in the calculated column.

Note that you actually define the calculated column's type, so you can have the output in any format you want.

Best regards,

Henrique.

Hi Sneha,

you can't modify the "deep" structure of a table (Names, SQL Data Types an Column Store Data Types).

Cheers,

Hi Sneha,

The functions which you are referring to are the Conversion Functions that can be found under the 'Calculated Columns'.

These functions actually create a new column in the views-NOT in the persistence layer(actual tables).

These functions will just create a new column with the datatype you want.

If you wish to change the data type in the base tables, you may also go for changing the type in SAP LT configurations as well

Refer the SAP LT configuration guides here http://help.sap.com/hana_appliance/
