While below is ok:
select * from table_a a where (select data_a from table_a where id = a.id) > (select data_b from table_a
whereid = a.id);
but this fails:
select * from table_a a where ((select data_a from table_a where id = a.id) > (select data_b from table_a
whereid = a.id));
ERROR: parser: parse error at or near ">"
Does anybody know why?
