Dear all

I am trying to update a table via a database link in a stored pl/sql procedure.

At the beginning of my pl/sql procedure, I have added the following statement:

execute immediate 'alter session set global_names=TRUE';
but unfortunately, I am still getting the error:
ORA-02069: global_names parameter must be set to TRUE for this operation
Please can someone explain why I am still getting this error - and the steps I can make to fix it?
Many thanks
