Performance issue in ORACLE FORMS

Question

I USED REF CURSOR TO LOAD DATA TO NON DATABASE BLOCK. IT GETS AROUND 50 MINUTES TO LOAD DATA.BUT IN SQL PLUS I RUN THIS QUERY WITH SAME PARAMETES.IT SHOWS RESULTS VERY QUICKLY.(INDEXES ARE ALREDY CREATED ).
WHAT CAN BE THE ISSUE TO TAKE LONG TIME TO VIEW DATA IN THE FORM.
CAN ANY BODY HELP TO SOLVE MY PROBLEM.
THANKS.

Answer 1

the difference in time is that you doing the following additional tasks in forms that you dont do in sqlplus:
1. you are retrieving data into the fields of the form.
2. creating the record.
which is a network round-trip for each record. AFAIK.
if its an option for you, I would create a global temporary table and then populate the temporary table with the required data. Then build a base table block based on the global temporary table. This way you can use the forms default functionality and its fast because you dont have to populate all the records on the form before you see the first record!
