Fix parsing of SETTINGS clause of the INSERT ... SELECT ... SETTINGS query Before this patch the following query ignores the settings for INSERT: insert into test_parallel_insert select * from numbers_mt(655352) settings max_insert_threads=10 And the reason is that SETTINGS was parsed by the SELECT parser. Fix this by push down the SETTINGS from the SELECT to INSERT. Also note that since INSERT parser does not use ParserQueryWithOutput the following works: insert into test_parallel_insert select from numbers_mt(65535*2) format Null settings max_insert_threads=10 2020-11-25 18:32:52 +00:00			`drop table if exists data_01593;`
