You can use atomic just over the section that causes the error. The issue is that different db engines have different semantics under error during transaction. Rolling back to the last savepoint (as atomic does when nested) recovers the ability to complete the remainder of the transaction. With a savepoint to roll back to, in some DBs, the full transaction is lost. On Mar 14, 2016 11:09 AM, "Tore Lundqvist" <t...@mima.x.se> wrote:
