how to use the Oracle/PLSQL SQLERRM function with syntax and examples. What does the SQLERRM Function do? The SQLERRM function returns the error message associated with the most recently raised error exception. This function should only be used within the Exception Handling section of your code. Syntax The syntax for the SQLERRM function in Oracle/PLSQL is: SQLERRM functions for error trapping are contained in which section of a pl/sql block 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 Terms of Service and Privacy Policy.

and returns control to the operating system. With PL/SQL, a mechanism called exception handling lets you sqlerrm line number bulletproof your program so that it can continue operating in the presence of errors.

Exceptions https://docs.oracle.com/cd/B19306_01/appdev.102/b14261/errors.htm can be internally defined (by the runtime system) or user defined. Examples of internally defined exceptions include division by zero and out of memory. Some common internal exceptions have predefined names, such as ZERO_DIVIDE and STORAGE_ERROR. The other internal exceptions can be given names. You can define exceptions of your own in the declarative part of any PL/SQL block, subprogram, or package. For example, you might define an exception named insufficient_funds to flag overdrawn bank accounts. Unlike internal exceptions, user-defined exceptions must be given names. When an error occurs, an exception is raised. That is, normal execution stops and control transfers to the exception-handling part of your PL/SQL block or subprogram. Internal exceptions are raised implicitly (automatically) by the run-time system. User-defined exceptions must be raised explicitly by RAISE statements, which can also raise predefined exceptions. To handle raised exceptions, you write separate routines called exception handlers. After an exception handler runs, the curre

Join them; it only takes a minute: Sign up How to catch and return (or print) an exception in an ORACLE PL/SQL create pl sql or replace stored procedure up vote 8 down vote favorite 1 I have a PL/SQL stored procedure inside which I want to run several updates, then capture any exceptions and return them in an out parameter. For simplicitys sake in the code block below I am simply outputting the exception code and error message to the console. However, the code block below does not work (I am experiencing a "found / pl sql display expecting" syntax error) CREATE OR REPLACE PROCEDURE DBP.TESTING_SP AS DECLARE v_code NUMBER; v_errm VARCHAR2(64); BEGIN UPDATE PS_NE_PHONE_TBL SET NE_PHONE_TYPE = 'TEST' WHERE NEMPLID_TBL = 'N14924'; EXCEPTION WHEN OTHERS THEN v_code := SQLCODE; v_errm := SUBSTR(SQLERRM, 1, 64); DBMS_OUTPUT.PUT_LINE (v_code || ' ' || v_errm); END TESTING_SP; / What is the correct syntax for what I am trying to do? I read on one forum "When using the Create or Replace syntax, you can not use Declare. Declare is only for anonymous blocks that are not named. So either remove line 1 and create an anonymous block, or remove line 2 and create a named procedure." but I'm not sure how to create an anonymous block or create a named procedure to accomplish what I want to do (if that, indeed, is the 'solution'). Could somebody lend a hand? oracle stored-procedures plsql share|improve this question edited Sep 8 '12 at 2:56 asked Sep 8 '12 at 2:48 n00b 1,26821544 Unless you are are doing something useful with the exception information, there is no need to catch it. The best way to pass exception information to the calling function is to do nothing, and let the exception naturally raise. This uses less code and preserves the real line number
Functions PSOUG Forum Oracle Blogs Search the Reference Library pages: FreeOracle MagazineSubscriptionsand Oracle White Papers Oracle Exception Handling Version 11.1 General NOTE: How Oracle Does Implicit Rollbacks Before executing an INSERT, UPDATE, or DELETE statement, Oracle marks an implicit savepoint (unavailable to you). 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 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. 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 ref
