With many programming languages, unless you disable error checking, a run-time error such oracle pl sql exception error message as stack overflow or division by zero stops normal processing and returns control to the operating system. With PL/SQL, a mechanism called exception handling lets you "bulletproof" your program so

Exceptions 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 current block stops executing and the enclosin

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 https://www.techonthenet.com/oracle/exceptions/sqlerrm.php 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.

What is the WHEN OTHERS clause in Oracle? The WHEN OTHERS clause is used to trap all remaining exceptions that have not oracle pl sql been handled by your Named System Exceptions and Named Programmer-Defined Exceptions. Syntax We will take a look at the syntax for the WHEN OTHERS clause in both procedures and functions. Syntax for Procedures The syntax for the WHEN OTHERS clause in a procedure is: CREATE [OR REPLACE] PROCEDURE procedure_name [ (parameter [,parameter]) ] IS [declaration_section] BEGIN executable_section EXCEPTION WHEN exception_name1 THEN [statements] WHEN exception_name2 THEN [statements] WHEN exception_name_n THEN [statements] WHEN OTHERS THEN [statements] END [procedure_name]; Syntax for Functions The syntax for the WHEN OTHERS clause in a function is: CREATE [OR REPLACE] FUNCTION function_name [ (parameter [,parameter]) ] RETURN return_datatype IS | AS [declaration_section] BEGIN executable_section EXCEPTION WHEN exception_name1 THEN [statements] WHEN exception_name2 THEN [statements] WHEN exception_name_n THEN [statements] WHEN OTHERS THEN [statements] END [function_name]; Example Here is an example of a procedure that uses a WHEN OTHERS clause: CREATE OR REPLACE PROCEDURE add_new_order (order

How can I rewrite the following to catch only the error ORA-00955? begin EXECUTE IMMEDIATE 'CREATE SEQUENCE S_TEST START WITH 1 INCREMENT BY 1'; exception when OTHERS then Null; end; BTW Is there any syntax to catch errors by just providing the error-codes? oracle exception share|improve this question edited Dec 20 '11 at 9:30 Sathya 98431333 asked Dec 20 '11 at 6:56 bernd_k 5,530185595 add a comment| 2 Answers 2 active oldest votes up vote 18 down vote accepted You have two options: Refer to the exception directly by number: BEGIN EXECUTE IMMEDIATE 'CREATE SEQUENCE S_TEST START WITH 1 INCREMENT BY 1'; EXCEPTION WHEN OTHERS THEN IF SQLCODE = -955 THEN NULL; -- suppresses ORA-00955 exception ELSE RAISE; END IF; END; Other option is to use EXCEPTION_INIT Pragma directive to bind a known Oracle error number to user defined exception; DECLARE name_in_use exception; --declare a user defined exception pragma exception_init( name_in_use, -955 ); --bind the error code to the above BEGIN EXECUTE IMMEDIATE 'CREATE SEQUENCE S_TEST START WITH 1 INCREMENT BY 1'; EXCEPTION when name_in_use then null; --suppress ORA-00955 exception END; BTW Is there any syntax to catch errors by just providing the error-codes?
