Executing an INSERT statement in PS mode having positional parameter bound with an array could result in incorrect number of inserted rows in case there is a BEFORE INSERT trigger that executes yet another INSERT statement to put a copy of row being inserted into some table. The reason for incorrect number of inserted rows is that a data structure used for binding positional argument with its actual values is stored in THD (this is thd->bulk_param) and reused on processing every INSERT statement. It leads to consuming actual values bound with top-level INSERT statement by other INSERT statements used by triggers' body. To fix the issue, reset the thd->bulk_param temporary to the value nullptr before invoking triggers and restore its value on finishing its execution. |
