I am using Oracle 10g and using following script to create the job
CREATE OR REPLACE PROCEDURE archtemp AS
BEGIN
UPDATE ARCH_TEMP SET ARCH_DATE = SYSDATE;
COMMIT;
END archtemp;
VAR jobno NUMBER;
BEGIN
DBMS_JOB.SUBMIT(:jobno, 'archtemp;', SYSDATE, 'sysdate + 1/1440');
COMMIT;
END;
The job never executes automatically (though it runs manually) with following error in alert_sid.log
ORA-12012: error on auto execute of job 26
ORA-01422: exact fetch returns more than requested number of rows
ORA-06512: at line 8
I am unable to link the ORA-01422 error with any of my code. I'm not doing any fetch here.
Assuming this is a script for SQL*Plus, there are two / misssing, so it does nothing at all:
CREATE OR REPLACE PROCEDURE archtemp AS
BEGIN
UPDATE ARCH_TEMP SET ARCH_DATE = SYSDATE;
COMMIT;
END archtemp;
/
VAR jobno NUMBER;
BEGIN
DBMS_JOB.SUBMIT(:jobno, 'archtemp;', SYSDATE, 'sysdate + 1/1440');
COMMIT;
END;
/
I guess it's another job failing, not yours.
You don't do any data fetch here, but I guess some ON UPDATE trigger on ARCH_TEMP table might. Check it.
I'd use a SERVERERROR trigger (as described here) to try to catch the statement that is failing. But first, you could check the alert log. If recursive SQL is erroring, there may be a problem in the data dictionary.
Try putting in an explicit PL/SQL block as the WHAT parameter.
dbms_job.submit(v_jobno, 'begin archtemp; end;', sysdate, 'sysdate+1/1440');
Here's my test case, which seems to work fine:
create table arch_temp (
arch_date date
);
-- create row to test update
insert into arch_temp (arch_date) values (null);
create or replace procedure archtemp as
begin
update arch_temp set arch_date = sysdate;
commit;
end archtemp;
/
-- test everything works in isoloation
begin
archtemp;
end;
/
select * from arch_temp;
-- arch_date = 10:49:34
select * from user_jobs;
-- no rows returned
declare
v_jobno number;
begin
dbms_job.submit(v_jobno, 'begin archtemp; end;', sysdate, 'sysdate+1/1440');
commit;
dbms_output.put_line('v_jobno: ' || to_char(v_jobno));
end;
/
-- dbms_output...
-- v_jobno: 50520
select * from user_jobs;
-- JOB 50520 returned
-- LAST_DATE = 10:51:11
select * from arch_temp;
-- ARCH_DATE = 10:51:11
I tried solution by Nick Pierpoint as well but it didn't work for me
It looks something is wrong with LUCK because i tried the same thing on another machine having Oracle 9i and it failed!!!
Thank you all for your replies.

I am receiving the following error when trying to compile and execute. I am having issues how to figure this out.

As you were told, you can't use EXISTS out of the SELECT statement. Therefore, you'll have to check for existence in the AGENT table elsewhere.
Here's one option you might consider. Note that I've also rewritten the INSERT INTO statement - there's no need to SELECT FROM DUAL, you already have all those values.
CREATE OR REPLACE PROCEDURE AddAgent(
p_Agent_Fname IN Agent.Agent_Fname%TYPE,
p_Agent_Lname IN Agent.Agent_Lname%TYPE,
p_Agent_Address IN Agent.Agent_Address%TYPE,
p_Agent_Tsales IN Agent.Agent_Tsales%TYPE,
p_Agent_Salary IN Agent.Agent_Salary%TYPE)
IS
p_ErrorCode number; --USED FOR ERROR CHECKING
p_ErrorMsg Varchar2(200);
p_CurrentUser Varchar2(100);
l_cnt number; --> newly added
BEGIN
-- check whether something exists in a table
select count(*)
into l_cnt
from dual
where exists (select null
from agent
where agent_lname = p_agent_lname
);
IF l_cnt > 0 then
dbms_output.put_line('Failure');
ELSE
INSERT INTO Agent
(Agent_Fname, Agent_Lname, Agent_Address, Agent_Tsales, Agent_Salary)
VALUES
(p_Agent_Fname, p_Agent_Lname, p_Agent_Address, 0, p_Agent_Salary);
COMMIT;
dbms_output.put_line('Success');

I want include condition in my trigger, based on data from a table. As oracle to do allow subquery in trigger, how it can be achived. Please find my code below. Trans_code_master holds the list of valid code, which can be changed.
Thanks in advance for all your help.
CREATE OR REPLACE TRIGGER CUST_TRG
BEFORE INSERT OR UPDATE ON CUST_ALL_TRANS
REFERENCING OLD AS OLD NEW AS NEW
FOR EACH ROW
WHEN (NEW.TRANSACTION_CODE IN(SELECT TRANS_CODE FROM TRANS_CODE_MASTER))
BEGIN
INSERT INTO CUST_DEPO_TRANS
(
CUST_ID
,AC_ID
,TRANSACTION_CODE
)
VALUES(
:NEW.CUST_ID
,:NEW.AC_ID
,:NEW.TRANSACTION_CODE
)
EXCEPTION
WHEN OTHERS THEN
-- Consider logging the error and then re-raise
RAISE;
END;
/
Its not possible in write query in when clause. Try the below way
CREATE OR REPLACE TRIGGER CUST_TRG
BEFORE INSERT OR UPDATE ON CUST_ALL_TRANS
REFERENCING OLD AS OLD NEW AS NEW
FOR EACH ROW
DECLARE
V_CNT NUMBER;
BEGIN
SELECT COUNT(1) INTO V_CNT
FROM TRANS_CODE_MASTER
WHERE TRANS_CODE = NEW.TRANSACTION_CODE;
IF V_CNT > 0 THEN
INSERT INTO CUST_DEPO_TRANS
(
CUST_ID
,AC_ID
,TRANSACTION_CODE
)
VALUES(
:NEW.CUST_ID
,:NEW.AC_ID
,:NEW.TRANSACTION_CODE
)
END IF;
EXCEPTION
WHEN OTHERS THEN
-- Consider logging the error and then re-raise
RAISE;

I wrote a procedure in PL/SQL to delete rows from a table,However,if that record does not exist,then throws some error like this: DBMS_OUTPUT.PUT_LINE('No such record'); My procedure is:
CREATE OR REPLACE PROCEDURE del_cn2
(c_cntry_id IN COUNTRIES.COUNTRY_ID%TYPE
)
IS
v_error_code NUMBER;
BEGIN
DELETE from countries
WHERE country_id =c_cntry_id;
IF SQL%NOTFOUND THEN
DBMS_OUTPUT.PUT_LINE('No such record');
END IF;
EXCEPTION WHEN OTHERS THEN
v_error_code :=SQLCODE;
IF v_error_code =-2292 THEN
RAISE_APPLICATION_ERROR(-20004,'Organization '||TO_CHAR(c_cntry_id)||' site
details defined for it.');
END IF;
END;
/
However,when I execute this procedure and provide a record that does not exist in my table,it gives message "Procedure completed successfully" I am using this to execute:
Execute procedure del_cn2('JJ');
Can someone please suggest?
If you want an exception to be thrown when a value that does not exist in the table is passed in, you would need to actually throw an exception. You shouldn't use dbms_output for any sort of error output. That is a very simplistic debugging tool-- you shouldn't assume that the caller will ever be able to see that output.
My guess is that you want something like
CREATE OR REPLACE PROCEDURE del_cn2
(c_cntry_id IN COUNTRIES.COUNTRY_ID%TYPE
)
IS
BEGIN
DELETE from countries
WHERE country_id =c_cntry_id;
IF SQL%ROWCOUNT = 0
THEN
raise_application_error( -20001, c_cntry_id || ' no such value.' );
END IF;
END;
try to set serverout to ON
example:
create table tst_delete (col1 int);
create procedure p_test_delete as
BEGIN
DELETE FROM tst_delete
WHERE col1 = 1;
IF (SQL%NOTFOUND)
THEN
dbms_output.put_line('No records found');
END IF;
END;
then call the procedure in SqlPlus
SQL> exec p_test_delete;
PL/SQL procedure successfully completed
same issue that you described - no insformation...
next try with output activated
SQL> set serverout on
SQL> exec p_test_delete;
No records found
PL/SQL procedure successfully completed
SQL>
I am researching issues regarding oracle. I'm creating stored procedures and boot the following errors I also show them in the picture, I hope to help me resolve the error.

You can add variable v_count number :=0; in your procedure to check if value exists.
Example:
CREATE OR REPLACE PROCEDURE PROCEDURE_NAME(PARAMETERS) IS
V_COUNT NUMBER := 0;
BEGIN
SELECT COUNT(1)
INTO V_COUNT
FROM YOUR_TABLE
WHERE .. .
IF V_COUNT = 0 THEN INSERT ...
ELSIF UPDATE ...
COMMIT;
END IF;
END;
Merge is one way to do this. Another way is
INSERT INTO..
SELECT ....
FROM DUAL
WHERE NOT EXISTS (SELECT * FROM...)
I'm not going to try and transcribe your screenshot
I need to debug in pl/sql to figure times of procedures, I want to use:
SELECT systimestamp FROM dual INTO time_db;
DBMS_OUTPUT.PUT_LINE('time before procedure ' || time_db);
but I don't understand where the output goes to and how can I redirect it to a log file that will contain all the data I want to collect?
DBMS_OUTPUT is not the best tool to debug, since most environments don't use it natively. If you want to capture the output of DBMS_OUTPUT however, you would simply use the DBMS_OUTPUT.get_line procedure.
Here is a small example:
SQL> create directory tmp as '/tmp/';
Directory created
SQL> CREATE OR REPLACE PROCEDURE write_log AS
2 l_line VARCHAR2(255);
3 l_done NUMBER;
4 l_file utl_file.file_type;
5 BEGIN
6 l_file := utl_file.fopen('TMP', 'foo.log', 'A');
7 LOOP
8 EXIT WHEN l_done = 1;
9 dbms_output.get_line(l_line, l_done);
10 utl_file.put_line(l_file, l_line);
11 END LOOP;
12 utl_file.fflush(l_file);
13 utl_file.fclose(l_file);
14 END write_log;
15 /
Procedure created
SQL> BEGIN
2 dbms_output.enable(100000);
3 -- write something to DBMS_OUTPUT
4 dbms_output.put_line('this is a test');
5 -- write the content of the buffer to a file
6 write_log;
7 END;
8 /
PL/SQL procedure successfully completed
SQL> host cat /tmp/foo.log
this is a test
As an alternative to writing to a file, how about writing to a table? Instead of calling DBMS_OUTPUT.PUT_LINE you could call your own DEBUG.OUTPUT procedure something like:
procedure output (p_text varchar2) is
pragma autonomous_transaction;
begin
if g_debugging then
insert into debug_messages (username, datetime, text)
values (user, sysdate, p_text);
commit;
end if;
end;
The use of an autonomous transaction allows you to retain debug messages produced from transactions that get rolled back (e.g. after an exception is raised), as would happen if you were using a file.
The g_debugging boolean variable is a package variable that can be defaulted to false and set to true when debug output is required.
Of course, you need to manage that table so that it doesn't grow forever! One way would be a job that runs nightly/weekly and deletes any debug messages that are "old".
use
set serveroutput on;
for example:
set serveroutput on;
DECLARE
x NUMBER;
BEGIN
x := 72600;
dbms_output.put_line('The variable X = '); dbms_output.put_line(x);
END;
If you are just testing your PL/SQL in SQL Plus you can direct it to a file like this:
spool output.txt
set serveroutput on
begin
SELECT systimestamp FROM dual INTO time_db;
DBMS_OUTPUT.PUT_LINE('time before procedure ' || time_db);
end;
/
spool off
IDEs like Toad and SQL Developer can capture the output in other ways, but I'm not familiar with how.
In addition to Tony's answer, if you are looking to find out where your PL/SQL program is spending it's time, it is also worth checking out this part of the Oracle PL/SQL documentation.
Using UTL_FILE instead of DBMS_OUTPUT will redirect output to a file:
http://oreilly.com/catalog/oraclebip/chapter/ch06.html
As a side note, remember that all this output is generated in the server side.
Using DBMS_OUTPUT, the text is generated in the server while it executes your query and stored in a buffer. It is then redirected to your client app when the server finishes the query data retrieval. That is, you only get this info when the query ends.
With UTL_FILE all the information logged will be stored in a file in the server. When the execution finishes you will have to navigate to this file to get the information.
Hope this helps.
Its possible write a file directly to the DB server that hosts your database, and that will change all along with the execution of your PL/SQL program.
This uses the Oracle directory TMP_DIR; you have to declare it, and create the below procedure:
CREATE OR REPLACE PROCEDURE write_log(p_log varchar2)
-- file mode; thisrequires
--- CREATE OR REPLACE DIRECTORY TMP_DIR as '/directory/where/oracle/can/write/on/DB_server/';
AS
l_file utl_file.file_type;
BEGIN
l_file := utl_file.fopen('TMP_DIR', 'my_output.log', 'A');
utl_file.put_line(l_file, p_log);
utl_file.fflush(l_file);
utl_file.fclose(l_file);
END write_log;
/
Here is how to use it:
1) Launch this from your SQL*PLUS client:
BEGIN
write_log('this is a test');
for i in 1..100 loop
DBMS_LOCK.sleep(1);
write_log('iter=' || i);
end loop;
write_log('test complete');
END;
/
2) on the database server, open a shell and
tail -f -n500 /directory/where/oracle/can/write/on/DB_server/my_output.log
An old thread, but there is another alternative.
Since 9i you can use pipelined table function.
First, create a type as a table of varchar:
CREATE TYPE t_string_max IS TABLE OF VARCHAR2(32767);
Second, wrap your code in a pipelined function declaration:
CREATE FUNCTION fn_foo (bar VARCHAR2) -- your params
RETURN t_string_max PIPELINED IS
-- your vars
BEGIN
-- your code
END;
/
Replace all DBMS_OUTPUT.PUT_LINE for PIPE ROW.
Finally, call it like this:
SELECT * FROM TABLE(fn_foo('param'));
Hope it helps.
Try This:
SELECT systimestamp INTO time_db FROM dual ;
DBMS_OUTPUT.PUT_LINE('time before procedure ' || time_db);
