but now I have to use oracle 9i application server and oracledatabase,I need deploy a form to 9i application server,
so I use form 9i open this form and save,then test run....but cannot query a record,it give me frm- 4050 error,but I don't know why cannot query a result?
how can i do? when i deploy this form on application server, how can i use this form query a record.

Maybe there is a bug in Forms9i. I have no experience with Forms9i. I use Forms6i patch 12. In this patch on client/server I use OLE for manipulation with BLOB column. In the lower patches of Forms6i there have been problems with BLOB columns there. We could not make query when BLOB column has been there. So we have decided to use OLE.

What is ORA error when you display error (like pressing Shift+F1 in Forms 6i) ?
