title: Is it possible to generate a unique numeric value for each row in an iSeries table without looping?
body: <p>I have an iSeries table with thousands of rows, and a new numeric/integer column was just added as the table Key. This will basically be a integer id column (1,2,3...). </p>
  
  <p>Let's say that I can't make this column an auto-incrementing column. Is there an simple way to assign unique, incremental values to each row without having to loop through each record assigning a value? Perhaps some kind of UPDATE query?</p>
