shot at without result. —Winston Churchill Run-time errors arise from design faults, coding mistakes, hardware sqlerrm in oracle failures, and many other sources. Although you cannot anticipate all oracle raise exception with message possible errors, you can plan to handle certain kinds of errors meaningful to your PL/SQL pl sql exception handling examples program. With many programming languages, unless you disable error checking, a run-time error such 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 that it can continue operating in the presence of errors.

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-hand

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 been handled by your Named System Exceptions and Named Programmer-Defined Exceptions. Syntax We will take oracle sql error 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_id_in IN NUMBER, sales_in IN NUMBER) IS no_sales EXCEPTION; BEGIN IF sales_in = 0 THEN RAISE no_sales; ELSE INSERT INTO orders (order_id, total_sales ) VALUES ( order_id_in, sales_in ); END IF; EXCEPT

Oracle Exception Handling tips Oracle Database Tips by Burleson Consulting Exception Handling in PL/SQL In any procedural language, it is critical to remember that the programs are a complete and separate entity from the database. Hence, whenever the program requests rows from the database, the programmer must make sure that the request completed successfully. In relational databases, the database will always pass a special variable called SQLCODE back to any calling program. The SQLCODE returned from reach call from the program to the database is translated by Oracle into a named Boolean variable (See table below). PL/SQL Exception Variable Oracle Error SQLCODE Value ACCESS_INTO_NULL ORA-06530 -6530 CASE_NOT_FOUND ORA-06592 -6592 COLLECTION_IS_NULL ORA-06531 -6531 CURSOR_ALREADY_OPEN ORA-06511 -6511 DUP_VAL_ON_INDEX ORA-00001 -1 INVALID_CURSOR ORA-01001 -1001 INVALID_NUMBER ORA-01722 -1722 LOGIN_DENIED ORA-01017 -1017 NO_DATA_FOUND ORA-01403 +100 NOT_LOGGED_ON ORA-01012 -1012 PROGRAM_ERROR ORA-06501 -6501 ROWTYPE_MISMATCH ORA-06504 -6504 SELF_IS_NULL ORA-30625 -30625 STORAGE_ERROR ORA-06500 -6500 SUBSCRIPT_BEYOND_COUNT ORA-06533 -6533 SUBSCRIPT_OUTSIDE_LIMIT ORA-06532 -6532 SYS_INVALID_ROWID ORA-01410 -1410 TIMEOUT_ON_RESOURCE ORA-00051 -51 TOO_MANY_ROWS ORA-01422 -1422 VALUE_ERROR ORA-06502 -6502 ZERO_DIVIDE ORA-01476 -1476 For example, if the database returns a SQLCODE=100, the PL/SQL variable NO_DATA_FOUND will be set to TRUE.
