I have a table that Im working with and it has a sequence to get the next value for the ID field on the table. The ID field is NOT a primary key. I want to change it but for now I see it has dependencies and I dont want to mess anything up. I noticed that when I did an Insert it is inserting a duplicate value of 3 into the this field. I opened the Sequence and the Last Number is now 3 so I understand how this happened. My question is, can I have the LastNumber look at my ID field and determine the next number? Or does this have to be a primary key in order for that to happen?
Thanks for any help!!
