Oracle / PLSQL: SQLERRM Function This Oracle tutorial explains 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 sqlerrm invalid identifier of 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 accepte

Note: DBMS_UTILTY.FORMAT_ERROR_STACK sqlerrm length is recommended over SQLERRM, except when using the FORALL statement with oracle sql codes list its SAVE EXCEPTIONS clause.

Syntax sqlerrm_function ::= oracle sqlcode values 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 numbers, see https://www.techonthenet.com/oracle/exceptions/sqlerrm.php 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, SQLERRM returns ORA-01403. https://docs.oracle.com/cd/B28359_01/appdev.111/b28370/sqlerrm_function.htm 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.

Churchill Run-time errors arise from design faults, coding mistakes, hardware failures, and many other sources. Although you cannot anticipate all possible https://docs.oracle.com/cd/B10500_01/appdev.920/a96624/07_errs.htm errors, you can plan to handle certain kinds of errors meaningful to your PL/SQL 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 oracle sql that it can continue operating in the presence of errors. This chapter discusses the following topics: Overview of PL/SQL Error Handling Advantages of PL/SQL Exceptions Predefined PL/SQL Exceptions Defining Your Own PL/SQL Exceptions How PL/SQL Exceptions Are Raised How PL/SQL Exceptions Propagate Reraising a PL/SQL Exception Handling Raised PL/SQL Exceptions Tips for Handling PL/SQL Errors Overview of PL/SQL Error error message sqlerrm Handling In PL/SQL, a warning or error condition is called an exception. Exceptions can be internally defined (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 enc
