replication problems DELETE HISTORY did not process parameterized PS properly as the history expression was checked on prepare stage when the parameters was not yet substituted. In that case check_units() succeeded as there is no invalid type: Item_param has type_handler_null which is inherited from string type and this is valid type for history expression. The warning was thrown when the expression was evaluated for comparison on delete execution (when the parameter was already substituted). The fix postpones check_units() until the first PS execution. We have to postpone where conditions processing until the first execution and update select_lex.where on every execution as it is reset to the state after prepare. |
