Jason,

I have a small problem with TIBOQuery.

If I have some code in event on OnPrepareSql referencing some fields to
limit returned rows, and in a button I call TIBOQuery1.Refresh without to
call TIBOQuery.InvalidateSql before, I get an error saying 'Field XXXX not
found'.

This error appears also when we have a navigator bar and clicking on Refresh
Button.

PS: IBO4.2Gc and D6.

Luiz.
