>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.

I'm sorry, I don't know :( Can not think about your problem right now, may be later or somebody else has ideas.
