soterd procedure cursor infinite loop

soterd procedure cursor infinite loop

(OP)
I'm using Pervasive Database v8.7 and I have the following stored
procedure that It doesn't work and goes into a endless loop.

Is it that this database doesn't support nested cursors?

thank you.

CREATE PROCEDURE populate_test() AS
BEGIN

DECLARE :v_parent CHAR(20);
DECLARE :v_part1 CHAR(20);

declare x cursor for
select distinct parent from BOM_MSTR;

open x;

delete from BOM_TEST3;

INSLOOP:
LOOP

IF SQLSTATE = '02000' THEN
   LEAVE INSLOOP;
END IF;

FETCH NEXT FROM x INTO
 :v_parent;

           declare y cursor for
           select distinct part from BOM_MSTR
           where parent=:v_parent;

           open y;
           INSLOOP2:
           LOOP
          IF SQLSTATE = '02000' THEN
             LEAVE INSLOOP2;
         END IF;


           FETCH NEXT FROM y INTO
           :v_part1;

           START TRANSACTION;

           INSERT INTO BOM_TEST3 (Parent,Part,lvl)
                       values (:v_parent,:v_part1,1);
           COMMIT WORK;

           END LOOP;
           CLOSE y;

END LOOP;
CLOSE x;
END

RE: soterd procedure cursor infinite loop

I would suggest adding some Print statements so you know which part is actually causing the loop.  
Also, how many records are you dealing with?  It's possible that it's not stuck in a loop but is just taking longer than expected.  How long have you left it running?

It getting stuck in the second loop in the insert statement, and it keeps inserting the same records over and over again. the table has about 7000 records

Aparently the exit condition is never met and the fetch keeps returning the last record..

IF SQLSTATE = '02000' THEN
       LEAVE INSLOOP2;
END IF;  

is not working.

RE: soterd procedure cursor infinite loop

And is BOM_TEST3 filling up?  
How long have you let it run?

yes..with millions of records...it keeps inserting the last record. The fetch from the second cursor returns that last record all the time and it never leaves that loop.
