Hi,

i wanted to log commits and looked at the sqlpreview event.

But it doesnt seem to be called by an commit - commit using tr; etc.

I dont know if that is a bug or if it is intended to be like this.

Does someone know?

 

Regards,

Ferdinand

Hi Ferdinand, I believe it has been like this since transaction object got its own SQLPreview. I just tested with absolutely latest bits available and find same behavior remains.

Note: SQLPreview is silent to both COMMIT and ROLLBACK.

You may opt for dynamic SQL =

EXECUTE IMMEDIATE "COMMIT" USING SQLCA;

This fires SQLCA's SQLPreview with SQLFunc = SQLDBOthers! and SQLSyntax = "COMMIT"

I know not a favorable workaround. I would consider log it as feature request.

Hi Ferdinand;

   If you sub-class your own SQLCA (aka "descendant"), then you can then control the capture of these DML commands ...

Example (STD Framework) ...

Food for thought.

Hi Ferdinand;

   Unfortunately, you are correct .. the "Commit" SQL command is not traced in the Transaction Object's SQLPreview event.

   This would need to be an enhancement request.

Regards ... Chris
