Hi Fehmi,
Welcome to UT!

The string comparison in foxpro is always case sensitive. Following select

Select * from customer where typ = 'partner'

will return 0 records in VFP or thru ADO if actual value in typ field is 'PARTNER'. If values in typ field is stored always in upper case than you can uppercase only the right side of comparison.

Select * from customer where typ = UPPER('partner')
* If case in typ field is unknown or not guaranted
Select * from customer where UPPER(typ) = ('partner')

BTW, it's considered rude to post the same message in more than one category.
