In VFP, on native VFP table, I can do:

SELECT News.Numero FROM News;
 WHERE News.AddDate>={^2003/04/01 00:00:00} AND News.AddDate<={^2003/04/30 23:59:59};
 ORDER BY 2 ASC

This doesn't work in SQLExec(). How can I have a universal format which would fit both? Or, how can I adjust it in order to have another syntax which would work for SQL Server?
