upgrade to 4.2, now odbc cursor problem

Hi All, I am working with PHP for quite some time now. For this customer I am forced to use the windows version with a db2 database server. This has introduced some interesting problems. After the upgrade from 4.1.2 many query's on most (MOST) table's give this warning: Warning: SQL error: [Microsoft][ODBC Cursor Library] SQLGetData is not allowed on a forward-only (non-buffered) cursor, SQL state SL008 in SQLGetData in f:\inetpub\wwwroot\mr-sales-db2\include\connect.inc on line 21 now I am not sure what a cursor is, how many types of a cursor there are. Maybe somebody could shed some light on this, because I am stuck here. I can post more specifice information if needed. Kind regards, Joop Marijne WebXpose
