Disabling Sync Triggers for Session

On most database platforms, SymmetricDS uses session variables to prevent its triggers from capturing data while it synchronizes and saves incoming data. If you need to modify data without triggers capturing data, you can use the same session variables. Find your database in the sections below for specific instructions. Note that if you have enabled the "sync on incoming" feature in your configuration, the triggers will capture data regardless of the session variables.
