How to check with table for cursor..?

Question

How to check with table for cursor..?
Here I have Table temp_final_plan
Here i want to update if already exit...below is the procedure....

Answer 1

I'm not sure what you mean by, 'How to check with table for cursor..?' but I'll offer a comment on your Code Snippet. I think you want to know how to check if a record exists so you know if you need to perform an INSERT or an UPDATE.
Here is a snippet of your code. I'll put my comments in "Comment" style in your code.
-- Insert / Update final profit plan for final_update query using cursor
   FOR rec_final_update_el IN cur_final_update_el
   LOOP
/* There is no need to test for %NOTFOUND since you are using Cursor FOR Loop! 
** This construct automatically exits when the last record is processed. */
   EXIT WHEN rec_final_update_el%NOTFOUND;
/* Is this where you would like to know how to Check if the record already exist??
** I asked this because, 'rec_final_update_el.' is not valid syntax.  Are you looking for
** an Cursor Attribute or Method you can check here? 
** I would suggest a Primary Key or Unique Index on ENT, CENTER, and POST_ACCT
** on the TEMP_FINAL_PLAN table. Then simply perform an INSERT and code an
** Exception to UPDATE when you get a DUP_VAL_ON_INDEX exception.  Otherwise,
** you will need to simply run an Implicit or Explicit Cursor to test if the row exists and
** use this return value to determine if you should INSERT or UPDATE.  */
   IF rec_final_update_el. THEN
      UPDATE temp_final_plan
         SET sum_avg_mtd_01 = rec_final_update_el.sum_avg_mtd_01,
             sum_avg_mtd_02 = rec_final_update_el.sum_avg_mtd_02,       
             sum_avg_ytd_01 = rec_final_update_el.sum_avg_ytd_01,       
             sum_avg_ytd_02 = rec_final_update_el.sum_avg_ytd_02,       
       WHERE ent = rec_final_update_el.ent
         AND center = rec_final_update_el.center
         AND post_acct = rec_final_update_el.post_acct;
   ELSE
      INSERT INTO temp_final_plan VALUES(rec_final_update_el.ent,
                                         rec_final_update_el.center,
                                         rec_final_update_el.post_acct,
                                         rec_final_update_el.sum_avg_mtd_01,
                                         rec_final_update_el.sum_avg_mtd_02,
                                         rec_final_update_el.sum_avg_ytd_01,
                                         rec_final_update_el.sum_avg_ytd_02);
   END IF;
   END LOOP;I hope I've answered your question, but if I haven't please provide more details so we can better understand your request.
