EF-4 data provider error

Post by VS2013 » Mon 20 May 2013 11:48


I'm getting following error when trying to update model from database [For oracle database].

ERROR:- The data reader returned by the store data provider does not have enough columns for the query requested.

NOTE:- Previously it was working correctly.

Version details:-
Visual studio-2010[SP 1]
Devart dotConnect for Oracle-
Devart Entity Developer-
Oracle database version-11 g

Any help or hints on this topic are greatly appreciated. Thanks in advance.

Please send us a test model with the DDL script of the database objects you are choosing in Update Model From Database Wizard. Also specify the call stack of the exception.
