We have several different ways of entering orders onto our system so I thought a simple trigger would be a better solution then altering lots of frontend applications.It appears that the trigger is copying all rows from the original field into the field I want to keep a history of the original value.How can I ensure the only row that updates is the row just created, in sql2000?here is my trigger, thanks jasemillyUPDATE test SET col2 = col1 FROM testTue, 19 Feb 2013 02:39:05 GMTjason-810420
