Why does exception through me out of cursor loop? - oracle

Question

I have a PL/SQL oracle procedure,
I run over list of sql_id to tune them.
I have an exception , but it through me out and finish.
Tried it with or without continue, but it's the same..
ANY IDEAS?
CREATE OR REPLACE Procedure sql_perf_for_sql_id
IS
v_sql_id VARCHAR2(13);
stmt_task VARCHAR2(64 CHAR);
retcode VARCHAR2(64 CHAR);
cursor c1 is

FROM sql_for_tune
WHERE tuned='NO';
BEGIN
IF c1%ISOPEN THEN
CLOSE c1 ;
END IF;
open c1;
LOOP
--for r_c1 in c1 loop
BEGIN
fetch c1 into v_sql_id;
--v_sql_id := r_c1.sql_id;
exit when c1%notfound;
update sql_for_tune set remarks='RUNNING' where sql_id=v_sql_id;
commit;
stmt_task := NULL;
DBMS_OUTPUT.PUT_LINE (v_sql_id);
-- create a tuning task tune the statement
stmt_task := DBMS_SQLTUNE.CREATE_TUNING_TASK(sql_id => v_sql_id);
DBMS_OUTPUT.PUT_LINE( NVL(stmt_task,'Error CREATE_TUNING_TASK() Return Value'));
-- execute the resulting task
retcode := DBMS_SQLTUNE.EXECUTE_TUNING_TASK(stmt_task);
DBMS_OUTPUT.PUT_LINE( NVL(retcode,'Error EXECUTE_TUNING_TASK() Return Value'));
-- accept the resulting task
retcode := DBMS_SQLTUNE.ACCEPT_SQL_PROFILE(stmt_task);
DBMS_OUTPUT.PUT_LINE( NVL(retcode,'Error ACCEPT_SQL_PROFILE() Return Value'));
-- Optional SELECT DBMS_SQLTUNE.report_tuning_task( stmt_task ) AS recommendations FROM dual;

Answer 1

It exits because of
raise_application_error(-20001,'An error was encountered - '||SQLCODE||' -ERROR- '||SQLERRM);
If you want the loop to continue, don't raise the error - log it using some other way (for example, dbms_output.put_line being the simplest; store it into a table by using a call of the autonomous transaction procedure).
Also, remove all those COMMITs out of the loop. Commit once, at the end of the procedure.
