>The other problem, I am havin is that if I run a query in FoxPro or intantiate the class in foxpro I get the value the query should return, but If I instantiate it from the dll, and the sql command with the code above, I get a value that has nothing to do with the value. at the beginning I was thinking it was getting the value from other table, that is why i explicitly use alias.field, but still doesn't work.

lcAlias = SYS(2015)
SET ANSI ON 			
lcSQL = lcSQL + [ into cursor ]+lcAlias
&lcSQL
IF RECCOUNT(lcAlias) > 0
   lRetVal     = EVALUATE(lcAlias + "." + FIELD(1, lcAlias))
ELSE
   lRetVal = NULL	
ENDIF
