> create table A (a int, b int);
> create table B (c int, d int);
> insert into A values (1, 1);
> insert into A values (2, 2);
> sql:
> {code:sql}
> select * from A where A.a not in (select B.c from B where A.b > 1);
> {code}
> the equivalent logical tree:
> {code}
> LogicalProject(a=[$0], b=[$1])
> +- LogicalProject(a=[$0], b=[$1])
> +- LogicalJoin(condition=[AND(OR(=($0, $3), IS NULL($0), IS NULL($3)),
> $2)], joinType=[anti])
> :- LogicalProject(a=[$0], b=[$1], $f2=[>($1, 1)])
> : +- LogicalTableScan(table=[[A]])
> +- LogicalProject(c=[$0])
> +- LogicalFilter(condition=[true])
> +- LogicalTableScan(table=[[B]])
> {code}
> the correct result is: (1, 1), (2, 2)
> while if the predicate ($2 in join condition) is pushed into left side, the
> result is (2, 2) which is incorrect.
