sql fiddle on following: create table tbl( col1 int, col2 int, col3 int); insert tbl values(1,1,1); insert tbl values(1,1,1); select sum(col1) c1, sum(col2) c2, sum(col3)c3 tbl not exists ( select 2 c1, 2 c2, 2 c3 ) i expecting return 0 records. instead returns 1 record of null values. can tell me why? p.s. trying understand not exists behavior. it's not exists . not exists evaluates false , since select 2 c1, 2 c2, 2 c3 returns row. means query equivalent to: select sum(col1) c1, sum(col2) c2, sum(col3) c3 tbl 0 saying that, sum semantics. sum in empty set should return value, , value in case null . from mysql documentation : sum(expr) returns sum of expr. if return set has no rows, sum() returns null. sum() returns null if there no matching rows.
