See in borland.public.attachments I have this code which works fine with BCB6, but with BDS2006 BDE tells me that 1 parameter is expected. I ran the SQL Query directly to the database and it works well, so.... I think that the error could be in the line between /********/ , exactly in -> _concepto+\" \"+B.desc_ <- I need to concatenate an space to show it in the query result, but why now crashes? Note: To execute in access I need to change \" \" for \' \' , instead errors.
