During the execution of explicit cursor, I need to insert the returned value of the same query into different columns.
The column names are v1_50, v2_50,.....v10_50. First value in col v1_50, the second value in the same row in col v2_50, the third value in col v3_50 of same row and so on.

Please guide.

Is your question Reports or Discoverer related? I don't know Discoverer, but - where do you execute this "explicit cursor"? In one of reports' triggers? Why did you decide to do it that way? I mean, what's wrong with an ordinary SQL query as report's data source? Why would you need a cursor?

What "columns" are you talking about? Table columns? If so, does it mean that you'd like to INSERT these values into a database? As you use a cursor, create a loop and insert cursor record values into a table.

I'm afraid I have no idea what you are talking about ./fa/1600/0/

Dear Littlefoot,


The need of explicit cursor arises because there are some calculations to be inserted to a column, based upon the user enterd values, before generating a report.

The parameters for the report are passed from objects on the form(in the oracle form builder and Not parameter form in the oracle report builder). the cursor is to be executed from the form object(on oracle form builder) and the returned values are to be inserted in the temp table. Then from that temp table using a simple SELECT statment, the report is to be generated.

I hope you have understood my problem.

OK, so it seems that
LF
create a loop and insert cursor record values into a table.
might, actually, work. Something like this:
FOR cur_r IN (SELECT c1, c2, c3 FROM some_table WHERE condition)
LOOP
   INSERT INTO temp_table 
     (col1, col2, col3) 
     VALUES
     (cur_r.c1, cur_r.c2, cur_r.c3);
END LOOP;

Although, if it is possible, use pure SQL INSERT statement and avoid cursor completely, such as
INSERT INTO temp_table
  (col1, col2, col3)
  (SELECT c1, c2, c3 
   FROM some_table
   WHERE condition
  );
It will be more efficient than any PL/SQL solution. Once again - if it is possible.

Sorry!
its not working. When I tried it, the selected columns were inserted into some_table as they are in the parent table.

That's what you said, isn't it?

Anyway, what prevents you to modify my code and adjust it according to your needs?

I have already tried to modify it sir. The code I used was
INSERT INTO sam_rep2
(v1_100, v2_50)
(SELECT v1_100, v2_50
FROM sam_rep1)
I didn't use any WHERE condition.

The v1_100 and v2_50 columns in both the tables are exactly same.

Your query says: take all v1_100 and v2_50 columns from table "sam_rep1" and put them into v1_100 and v2_50 columns in "sam_rep2" table.

Shortly:
sam_rep1   sam_rep2
--------   --------
v1_100  -> v1_100
v2_50   -> v2_50

Yes, and it is expected as your INSERT statement does exactly what you've said.

If that's NOT expected behaviour, what would you like to do, then?
