Since you have version 9, this gets extremely simple with the cast() function. Specifically, you don't need to fool around with temporary tables or cursors:
SELECT MyField1, MyField2, CAST("" as M) as MyMemo;
FROM MyTable
>I'm trying to do that little trick to get a new memo field in a SQL, but can't quite recall how to do it. This is what I have, which returns an error on the SQL:
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
