I just had to go the execute_for_fetch route for yet another project, and it's surprisingly fast, thanks for that! :)

When dealing with MySQL or MariaDB this depends on the engine used, since I get an array of potential errors returned from execute_for_fetch ...

On InnoDB I can then decide to either ->commit or ->rollback and this works fine.

But on MyISAM transactions and rollbacks are not supported.

There I have to go the route of using intermediate temporary tables to be safe(r).
