What is the "context" in your case? All database blocks can be queried. Is that a database block, or a control block?

What is F7 mapped on your computer? Are you *sure* it is <enter query>? Check it in Help menu ("Keys").

What does "going to that block using WHEN-BUTTON-PRESSED and EXECUTE_QUERY" mean? I *know* what it means, but ... if you already are in that block and query is executed (you see some records, do you?), and F7 is out of context, well, my previous questions are raised again - what context is it and what is F7 mapped to?

thanks littlefoot, its a database block and i am unable to query that block."COntext" is the error messsage while querying its giving error message saying "Context has no meaning".Actually i am trying to go to a block after pressing when button pressed on the current block 'b'.I am using go_block('a') and then execute_query it displays all the records but again after retrieval, i want to go in enter_query and search that's not possible and i am getting this error message.

Well, that *should* work. If you already are in a (database) block 'A' and records are displayed (after you executed EXECUTE_QUERY), then <enter query> is perfectly valid in that context.

So, are you sure that F7 is really "enter query"?

What happens if you go to Query menu (while in block 'A') and select "Enter query"?

Wait a second ... "enter query" doesn't retrieve anything, it only lets you enter search criteria and then, when you press "execute query", records that satisfy these criteria are retrieved.

OK, so OV_EMP block is a database block, based on EMP_VIEW and query is allowed on that block. There are no block-level triggers there. I searched the form's PL/SQL for "ov_emp" (thinking that there might be SET_BLOCK_PROPERTY somewhere, but - nope, didn't find any).

At the moment, I have no idea why "enter query" / "execute query" wouldn't work on that block (except if no records satisfy criteria you entered, but that wouldn't raise "The function has no meaning in this context". Hopefully, someone else will know better.

Where exactly is the cursor when you press f7?
Are you sure emp_view returns data? Try querying it in sqlplus.

I have seen the fmb. I see no obvious reason for the problem. I suggest you trace the form session in the database and see what it's really doing.
