Hi. I have this table (A) IDJOB ¦ IDKIT
4 ¦ 19 4 ¦ 19 2 ¦ 19 2 ¦ 5 I need to extract IDKIT with IDJOB<>2 if and only if IDKIT <> IDKIT when IDJOB=2 In this case my query should return null With a subquery I can do this and it works SELECT idkit from A where A.id_job<>2 and A.id_kit not in (select A.id_kit from A where A.id_job=2) Anyone could suggest how I could do this in mysql without subquery?
