Pl Sql Error Handling Sqlerrm
Contents |
Churchill Run-time errors arise from design faults, coding mistakes, hardware failures, and many other sources. Although you cannot anticipate all possible errors, you can plan to handle oracle sql codes list certain kinds of errors meaningful to your PL/SQL program. With many programming languages,

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

Exceptions can be internally defined sqlerrm invalid identifier (by the run-time 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 current block stops executing and the enclosing block resumes with the next statement. If there is no enclosing block, control returns to the host environment. In the example below, you calculate and store a price-to-earnings ratio for a company with ticker symb
is useful only in an exception handler. Outside a handler, SQLERRM with no argument always returns the normal, sqlerrm length successful completion message. For internal exceptions, SQLERRM returns the message associated oracle sqlcode list with the Oracle error that occurred. The message begins with the Oracle error code. For user-defined sqlerrm column not allowed here exceptions, SQLERRM returns the message user-defined exception, unless you used the pragma EXCEPTION_INIT to associate the exception with an Oracle error number, in which case SQLERRM https://docs.oracle.com/cd/A97630_01/appdev.920/a96624/07_errs.htm returns the corresponding error message. For more information, see "Retrieving the Error Code and Error Message: SQLCODE and SQLERRM". Syntax sqlerrm function ::= Description of the illustration sqlerrm_function.gif Keyword and Parameter Description error_number A valid Oracle error number. For a list of Oracle errors (ones prefixed by ORA-), see Oracle Database Error Messages. Usage http://docs.oracle.com/cd/B19306_01/appdev.102/b14261/sqlerrm_function.htm Notes SQLERRM is especially useful in the OTHERS exception handler, where it lets you identify which internal exception was raised. The error number passed to SQLERRM should be negative. Passing a zero to SQLERRM always returns the ORA-0000: normal, successful completion message. Passing a positive number to SQLERRM always returns the User-Defined Exception message unless you pass +100, in which case SQLERRM returns the ORA-01403: no data found message. You cannot use SQLERRM directly in a SQL statement. Assign the value of SQLERRM to a local variable first, as shown in Example 13-6. When using pragma RESTRICT_REFERENCES to assert the purity of a stored function, you cannot specify the constraints WNPS and RNPS if the function calls SQLERRM.

Term: SQLERRM Definition: In Oracle PL/SQL, SQLERRM is an error trapping function which returns the predefined error message corresponding to the input error number argument. If no argument has been provided, SQLERRM returns the error message associated with the last standard pl sql error exception raised by the Oracle Server. It is defined in the Oracle STANDARD package. For user defined exceptions, SQLERRM returns the error message defined for an error number in PRAGMA EXCEPTION_INIT. If SQLERRM is invoked in the execution portion of the block, it returns "ORA-0000: normal, successful completion". Example Syntax: SQLERRM(Error Number) Example Usage: The PL/SQL block below raises ZERO_DIVIDE exception and displays the error message corresponding to error number -01476. DECLARE L_NUM1 NUMBER; L_NUM2 NUMBER; BEGIN L_NUM1 := 10; L_NUM2 := 0; DBMS_OUTPUT.PUT_LINE('RESULT:'||L_NUM1/L_NUM2); EXCEPTION WHEN OTHERS THEN DBMS_OUTPUT.PUT_LINE('Exception Message:'||SQLERRM); END; / Exception Message:ORA-01476: divisor is equal to zero PL/SQL procedure successfully completed.

Join them; it only takes a minute: Sign up How to catch and return (or print) an exception in an ORACLE PL/SQL create 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 / 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
