Here's 95% of the solution. All you have to do is figure out how you actually want to format the 0-255 numbers in the final column. Do note that the ASCII function works just fine for characters over 127. You just have to be careful to only pass it 1 character at a time.[code="sql"]--=============================================================================-- Create some test data.

My goal is to read each string from each record and convert each charter in that string to it's number equivalent, group the numbers for the string and update another column in the same table with the number. ASCII strings (shown here separated by commas) like.
