Hi,
Can you try to remove your SQL query line by line and see which line causes the error ? After that, we can try to find a solution.
Thanks.

Hi,
Sorry for wasting your time but this is an EF related problem I think and I don't have oracle installed :). Can you replace that line with this one
CASE WHEN ("Extent2"."Id" IS NULL) THEN N'.' ELSE "Extent2"."TenancyName" END AS "C2",and see if it works ?
If it works, you can apply the solution offered here I think <a class="postlink" href="http://stackoverflow.com/a/34665239">http://stackoverflow.com/a/34665239</a>.

Hi,
Yep, it's EF and Oracle problem, so I fixed by change type using VARCHAR2 instead NVARCHAR2
Thank you very much!
