* MDEV-21887: federatedx crashes on SELECT ... INTO query in select_handler codeSergei Petrunia2020-03-261-1/+12
| | | | | | | | | | | | Backport to 10.4: - Don't try to push down SELECTs that have a side effect - In case the storage engine did support pushdown of SELECT with an INTO clause, write the rows we've got from it into select->join->result, and not thd->protocol. This way, SELECT ... INTO ... FROM smart_engine_table will put the result into where instructed, and NOT send it to the client.
