AD_ZD_MVIEW.upgrade API is giving error message : ORA-22818: subquery expressions not allowed here
Hi All,
As per R12.2.4 standards, I have converted my Custom MVs by removing PL/SQL dependencies. When I start creating MVs using AD_ZD_MVIEW.upgrade API then I am getting ORA-22818: subquery expressions not allowed here message.
This could be resolved If I remove Sub queries in SELECT clause and move everything to FROM cluase but I have very complex Queries for MVs and it is hard to convert and also perfomance might come down.
Is there any way I can create MV with Sub queries. Kndly help.
Thanks
Raj
