Those 3 indexes would never be considered for use in SQL Server. It

will do a tablescan all the time.

If the user sees empno as 12334 but the data has it as 0001324 you

will have to append the "0" but I am sure you know that.

Dates in SQL Server are to the second, so [SQLServer] getdate() <>

date() [VFP] All of your dates coming from VFP may be set to midnight?

That would be great for now but you will get burned sooner or later

on it.

Always use a between in date searches
