The UNION does implicit DISTINCT on the resultset and DISTINCT is illegal for memo/general fields. You may want to use UNION ALL instead. See SET ENGINEBEHAVIOR Command for more info.
Also, in UNION query before VFP9 you can only specify fields by position not by name and expressions are not allowed in any VFP version.
