I have generated a number of sqlMaps using ibator. These are working great,
but now I would like to take advantage of compound properties to avoid N+1

column names so they become unique in the request set. Ibator will
Ok, that worked for me. I am able to copy/paste the fields from the
generated selects, and reuse the generated resultMaps. Thanks for the quick
