LINQ statement generates non-working SQL statement

Post by i.kopcanski » Fri 27 Aug 2010 08:52

I use Entity Framework 3.5 with .dotConnect for Oracle
The LINQ statement on Oracle EF model keeps with retrieving Oracle
error in executing generated PL SQL statement:

"ORA-00904: \"Project1\".\"C3\": invalid identifier"}
System.Exception {Devart.Data.Oracle.OracleException}

The part of LINQ statement which causes this exception is:

from gCol in gridColumnsRep.GetQuery(true)
where (gCol.v2_templates_grid_columns.v2_columns.freefields_settings == null
ffAdmin => ffAdmin.administration_id == currentProfile.AdministrationId))
&& == gridRequest.GridDefID
orderby gCol.display_order
select ...

Can you help us with this?

I can reproduce this error only in the case when the name of the property in the SSDL part of the model is not the same as the name of the corresponding column (be aware, the letters of the name in SSDL should be in the same case as the case of the letters in column names in database).

If this doesn't help, please send us a test project with your model and DDL.
