Since I installed VFP 8, I can't no longer have a GROUP BY 1 syntax. On the first occurence, I had to change it to GROUP BY Member.Numero. On the second notification of error, on a UNION SQL type, it doesn't want to accept that naming syntax as it's a union. So, I'm stuck. I really can't make that UNION SQL work anymore and I really don't understand why the GROUP BY 1 doesn't work.
