Re: EXEC Vs EXECUTE IMMEDIATE IN HANA?

Hi Sree,

Yes, you are right, in above example, you can display a result without using dynamic SQL construct.

But, what if in your above query, columns and order by statement are dynamic like mention below:

lv_sql_stat = 'SELECT ' || :col1 || ','||  :col2 || 'FROM tab ORDER BY '  || :lv_order_by || ';

You can run the above query using dymanic SQL as following two ways:

EXECUTE IMMEDIATE lv_sql_stat ;  => In this case, on calling the procedure, results of queries are appended to the procedures result iterator.

EXEC lv_sql_stat ; => In this case,on calling the procedures, you wont be able to see the result of the queries.

Hope this helps,

Best Regards,
