ORA-06502 = numeric or value error. In other words, parameter you used to fool Oracle Forms is invalid.
Did you ever open online Forms help and read what it has to say about the EXECUTE_QUERY built-in procedure? I believe not, because - if you had - you'd see what parameters are allowed.
I don't have Developer 6i so I can't test it myself and following words may be really stupid, but let me try: a view is, actually, stored SELECT statement. It is executed on database server. Forms uses view's output. Are you sure you can't use a VIEW as a data block source? Did you try it? If you got an error, which one was it?
How to fetch data into a control block? I never tried it (not the way it would simulate a database block). But, once you fill it, there's another problem: how to work with those data? UPDATE? DELETE? This and that? Phew, I'd rather avoid it if possible.

hi dear littelfoot,
i have solved my problem just by using a small cursor.
ya have checked it many time to use dbms_random package of database(backend) on form 6i but the error was atorderby clause of the queries.so it means the above package is not already stored in form 6i built-in packages .
anyways thatnx for ur time and advice.
andalos thanx for your early reply.
regards.
