| Note that this only compares the year. So there are 2 entries for 12 years (both Fred and Barney)But you can play with it....Charlie===============================================================Msg 3903, Level 16, State 1, Line 1736The ROLLBACK TRANSACTION request has no corresponding BEGIN TRANSACTION |
