What does the SQLERRM Function do? The SQLERRM function returns the error message associated with the most recently raised error exception.

your code. Syntax The syntax for the SQLERRM function in Oracle/PLSQL is: SQLERRM Parameters or Arguments There are no parameters or arguments for the SQLERRM function. Note See also the SQLCODE function. Example Since EXCEPTION HANDLING is usually written with the following syntax: EXCEPTION WHEN exception_name1 THEN [statements] WHEN exception_name2 THEN [statements] WHEN exception_name_n THEN [statements] WHEN OTHERS THEN [statements] END [procedure_name]; You could use the SQLERRM function to raise an error as follows: EXCEPTION WHEN OTHERS THEN raise_application_error(-20001,'An error was encountered - '||SQLCODE||' -ERROR- '||SQLERRM); END; Or you could log the error to a table using the SQLERRM function as follows: EXCEPTION WHEN OTHERS THEN err_code := SQLCODE; err_msg := SUBSTR(SQLERRM, 1, 200); INSERT INTO audit_table (error_number, error_message) VALUES (err_code, err_msg); END; NEXT: Declare Cursor Share this page: Advertisement Back to top Home | About Us | Contact Us | Testimonials | Donate While using this site, you agree to have read and accepted our T

::= Description of the illustration sqlerrm_function.gif Keyword and Parameter Descriptions error_number An expression whose value is an Oracle Database error number. For a list of Oracle Database error https://www.techonthenet.com/oracle/exceptions/sqlerrm.php numbers, see Oracle Database Error Messages. The default error number is the one associated with the current value of SQLCODE. Like SQLCODE, SQLERRM without error_number is useful only in an exception handler. Outside an exception handler, or if the value of error_number is zero, SQLERRM returns ORA-0000. If the value of error_number is +100, https://docs.oracle.com/cd/B28359_01/appdev.111/b28370/sqlerrm_function.htm SQLERRM returns ORA-01403. If the value of error_number is a positive number other than +100, SQLERRM returns this message: -error_number: non-ORACLE exception If the value of error_number is a negative number whose absolute value is an Oracle Database error number, SQLERRM returns the error message associated with that error number. For example: SQL> BEGIN 2 DBMS_OUTPUT.PUT_LINE('SQLERRM(-6511): ' || TO_CHAR(SQLERRM(-6511))); 3 END; 4 / SQLERRM(-6511): ORA-06511: PL/SQL: cursor already open PL/SQL procedure successfully completed. SQL> If the value of error_number is a negative number whose absolute value is not an Oracle Database error number, SQLERRM returns this message: ORA-error_number: Message error_number not found; product=RDBMS; facility=ORA For example: SQL> BEGIN 2 DBMS_OUTPUT.PUT_LINE('SQLERRM(-50000): ' || TO_CHAR(SQLERRM(-50000))); 3 END; 4 / SQLERRM(-50000): ORA-50000: Message 50000 not found; product=RDBMS; facility=ORA PL/SQL procedure successfully completed.

If the statement fails, Oracle rolls back to the savepoint. Normally, just the failed SQL statement is rolled back, not the whole transaction. However, if the statement raises an unhandled exception, the host environment determines what is rolled back. If you exit a stored subprogram with an oracle sql unhandled exception, PL/SQL does not assign values to OUT parameters. Also, PL/SQL does not roll back database work done by the subprogram. At the level of the SQL*Plus prompt, every update/insert/delete has one implicit savepoint, and also the invocation of any unnamed block. Below that, the unnamed block itself has 'sub' savepoints - one foreach insert/update/delete statement in it, and one for each subprogram unit. oracle error message And so on down the line. If an error occurs, and that error is handled at any level by the time we're back at the SQL*Plus prompt, we only rollback to the immediate savepoint at the start of the update/insert/delete that errors. Otherwise we rollback to the top-level 'virtual' savepoint currently in existence, which is my offending unnamed block. That is, a handled error is handled and so can be dealt with without rolling back all the way to the top. It is handled and the transaction proceeds. Commits define the end of a transaction (and start of a new one) - rollbacks only define the end of a transaction if they rollback to the last commit, rather than savepoint (whether explicit or implicit). I came to my 'version' from the following by no means exhaustive tests: CASE 1: I created a table a with one column, a1 number, and at the sqlplus prompt inserted a row with a1 = 1. I then ran that unnamed block I referred in an earlier post that, without an exception handler, does the following: INSERT INTO a VALUES (2); INSERT INTO a VALUES (3); INSERT IN
