Tune this Query please

dmohanty — Sun, 25 Aug 2013 17:35:41 GMT

Hi All,

I have a query like this below to fetch data from DB2. However this query can't be used directly in QVD Generator to create the QVD, as it starts with 'WITH' keyword.

I need this query to be tuned so that it can hit the data base DB2 (with ODBC drivers) and I can store this in a QVD. Can anyone help me in tuning this query, or any other help (using subqueries) would help too. Please help in writing this query in a QVW file.

Hello,

Try using below :

SUPP_REL_TABLE:

LOAD *;

SQL

with supp_assoc_rel as ( ..............

QV does not handle query execution, it leaves that the ODBC driver to that for us.

Once data is loaded to SUPP_REL_TABLE, it can then be used to store in a QVD.

Let me if it was helpful or anything else is required.

Thanks,

Angad

Hi Angad,

Thanks for the quick help. It seems I had missed the SQL statement in the query to write in QVW file.

Now I am able to create the QVD successfully and use it in the Data Model.

Thanks again.

Regards!!!
