Hi,

If i am getting a error in a procedure. how can i keep the record of this error in error log file. Do using Raise_application_error will automaticaly put the record in error log file? And how can i access error log file.

Regards,
Prashant

Well, you could create a log error TABLE and insert records in there (using an exception handler). Something like this:
EXCEPTION
  WHEN NO_DATA_FOUND THEN
    INSERT INTO log_error_table (when, who, what) 
    VALUES 
    (sysdate, 'procedure_1', 'No data found for customer ' || l_cust);
  WHEN TOO_MANY_ROWS THEN
    ...
After doing so, it is an easy task to write a report which would give you required information.

Yes like any other integer/string.

Well, it is just like MIchel told you and the way you said:
INSERT INTO log_error_table (err_code, err_message)
VALUES (SQLCODE, SQLERRM);

I am using the below code:


create table log_error_table (when date,err varchar2(20), msg varchar2(100))

declare
av sttm_customer.customer_no%type;
begin
select customer_no into av from sttm_customer where 1=2;
EXCEPTION
  WHEN NO_DATA_FOUND THEN
    INSERT INTO log_error_table  
    VALUES 
    (sysdate, sqlcode,sqlerrm);
end;


and i got following error while executing the code:

ORA-06550: line 9, column 23:
PL/SQL: ORA-00984: column not allowed here
ORA-06550: line 7, column 5:
PL/SQL: SQL Statement ignored


Please advice.

Regards,
Prashant

You need to create your table outside of the procedure

when is probably not a good choice for a column name. Choose something like update_date or error_date.

If you can't do it directly, then do it via a local variable.
Developing needs to switch one's brain on.

It is me to blame ... I apologize.

It won't work for the reason Michel said - sqlcode and sqlerrm can not be directly used; one has to use a variable. Here is an example:
SQL> CREATE TABLE log_err (datum DATE, err_code NUMBER, err_txt VARCHAR2(255));

Table created.

SQL>
SQL> DECLARE
  2    l_code log_err.err_code%TYPE;
  3    l_text log_err.err_txt%TYPE;
  4
  5    l_salary EMP.sal%TYPE;
  6  BEGIN
  7    -- this will raise NO_DATA_FOUND exception
  8    SELECT sal INTO l_salary
  9      FROM EMP
 10      WHERE empno = '1234';
 11
 12  EXCEPTION
 13    WHEN NO_DATA_FOUND THEN
 14      l_code := SQLCODE;
 15      l_text := SQLERRM;
 16
 17      INSERT INTO log_err
 18        (datum, err_code, err_txt)
 19         VALUES
 20        (SYSDATE, l_code, l_text);
 21  END;
 22  /

PL/SQL procedure successfully completed.

SQL>
SQL> SELECT * FROM log_err;

DATUM      ERR_CODE ERR_TXT
-------- ---------- -----------------------------------------------------------

24.07.07        100 ORA-01403: no data found

thanx.now its working fine.
1 more query.
Is there any table provided by the oracle for error log.
if yes will the error code defined by the user(by raise_application_error) will be inserted into that table?

Prashant

Perhaps you'll be interested in reading an article about DML error logging on OraFAQ pages, posted by Natalka Roshak (or even search for more information about this feature on the Internet / official Oracle documentation).
