Question

I am basically just trying to add 1 to a column in every row of the table whos primary key is not the minimum. I placed the code below. Can someone help me out with the logic?

    UPDATE MyTable
SET LineNumber = (case when TableID != min(TableID) then LineNumber + 1)
FROM MyTable

Answer 1

UPDATE  mt
SET     LineNumber = LineNumber + 1
FROM    MyTable mt
WHERE   TableID <> 
        (
        select  min(TableID) 
        from    MyTable
        )
