This pr add pull up literal when infer predicates, we can infer tmp.col1='abc' and tmp.col2 = 'def' from subquery tmp, pull up to inner join, and combined with join on condition, we can infer ds.col1='abc' and ds.col2='def' select * from ( select tmp.col1, tmp.col2 from ( select 'abc' as col1, 'def' as col2 from test_pull_up_predicate_literal ) tmp inner join test_pull_up_predicate_literal ds on tmp.col1 = ds.col1 and tmp.col2 = ds.col2 ) t where col1 = 'abc' and col2 = 'def'; --------- Co-authored-by: feiniaofeiafei <moailing@selectdb.com>
