Roy Lambert NLH Associates ![]() | UNION, INTERSECT, and EXCEPT Clauses
By default, non-distinct rows are aggregated into single rows in a UNION, INTERSECT, or EXCEPT operation. Use the ALL clause to retain non-distinct rows. I hope it should read distinct. If not 1) the little test I just tried returns the wrong result and 2) I can't get my head round why Roy Lambert |

Non-distinct rows are effectively made distinct in a UNION, INTERSECT, or EXCEPT operation. If what you're seeing doesn't jive with that, then send me the test that you're using and I'll take a look. -- Tim Young Elevate Software www.elevatesoft.com |

Its me - typing up a response here did something to my brain and I realised I had distinct and non-distinct reversed - sorry. Roy Lambert |
