Sergei Golubchik	5ad7f52558	MDEV-21603 Crashing SHOW TABLES with derived table in WHERE condition ... When you only need view structure, don't call handle_derived with DT_CREATE and rely on its internal hackish check to skip DT_CREATE. Because handle_derived is called from many different places, and this internal hackish check is indiscriminative. Instead, just don't ask handle_derived to do DT_CREATE if you don't want it to do DT_CREATE.	2021-05-04 09:01:55 +02:00
