I have a SQL like this.
SELECT A.HESAP_NO, A.TEKLIF_NO1 || '/' || A.TEKLIF_NO2 AS TEKLIF
MV_K(A.TEKLIF_NO1,A.TEKLIF_NO2, A.DATE) AS KV
FROM S_TEKLIF A
When i want calculate MV_K(A.TEKLIF_NO1,A.TEKLIF_NO2, A.DATE)/COUNT(@TEKLIF) but it doesn’t work.
I use Oracle.
How can i divide in Oracle like that?
Here is my FULL aspx code;

Obviously untested, but it should be something like:
Explanation: if you want to use count(*), you’d have to aggregate in your query, but you’re not doing that. So instead you can use an analytic function count(*) over () which counts the same number for each row.
Hope this helps.

Rob.
