Last updated on JANUARY 19, 2017

Applies to:

Oracle Database - Enterprise Edition - Version 11.2.0.4 and later
Information in this document applies to any platform.

Symptoms

Using PL/SQL Developer and Dg4ODBC to select from MySQL the 'where' clause in a SQL statement is dropped and the query takes a long time to run.
When using the same SQL and DG4ODBC instance from SQLPLUS or Oracle SQL*Developer then the 'where' clause is not dropped.
