Sergei Golubchik	8897b50dca	MDEV-11525 Assertion `cp + len <= buff + buff_size' failed in JOIN_CACHE::write_record_data ... Workaround for join_cache + index on vcols + keyread bug. Initialize the record to avoid caching garbage in non-read fields. A proper fix (do not cache non-read fields at all) is done in 10.2 in commits 5d7607f340f..8d99166c697	2017-02-27 12:35:10 +01:00
Igor Babaev	40c42468bc	Fixed LP bug #806057. ... A table expression with a natural join or a USING clause is transformed into an equivalent expression with equi-join ON conditions. If a reference to a virtual column happened to occur only in these generated equi-join conditions then it was not erroneously marked in the TABLE::vcol_set bitmap. This could lead to wrong results for queries containing natural join expressions or USING clauses.	2011-12-29 15:09:20 -08:00
