I want to use a RegExp to change a value incrementally everytime another column changes values.  Column A (which ends in a digit) repeats for x number of rows.  I need Column B to start at some number and increase by 1 for each row until Column A changes values.  I thought if I could grab that last digit and increment its value but this is way beyond my skills.  Can anyone help me.  Is it possible?  Or can I only add to the Insert Table Column Value?

                Natively, SQL Data Generator doesn't support updating one column from a generated value in another column of the same table.
The workaround for this was an (unsupported) third-party add-in for SDG that allowed you to generate the data using a Ruby script. (note: the built-in Python script generator sadly doesn't have this capability).
So you *could* use the Ruby gen to derive values from one column *or* you could use the Python generator on both columns to generate a predictable set of numbers that you know will result in the requirement being filled. - 
                
                  
                
                I think you're after something similar to this: http://www.red-gate.com/MessageBoard/vi ... hp?t=15979 - 
                
                  
                
                Brian, thanks, this will definately be helpful in a lot of circumstances only unfortuately in this particular case my TableA PK is not an integer, it's a string with alpha/numeric combination.
