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 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.

is useful only in an exception handler. Outside a handler, SQLERRM with no argument always returns the normal, oracle sqlcode values successful completion message. For internal exceptions, SQLERRM returns the message associated sqlerror with the Oracle error that occurred. The message begins with the Oracle error code. For user-defined

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://www.techonthenet.com/oracle/exceptions/sqlerrm.php 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. Examples For examples, see the following: Example 10-11, "Displaying SQLCODE and SQLERRM" Example 13-6, "Using SQLCODE and SQLERRM" Related Topics "Exception Definition" "SQLCODE Function" Scripting on this page enhances content navigation, but does not change the content in any way.
and you use the RESTRICT_REFERENCES pragma to assert its purity, you https://docs.oracle.com/cd/B28359_01/appdev.111/b28370/sqlerrm_function.htm cannot specify the constraints WNPS and RNPS. Note: DBMS_UTILTY.FORMAT_ERROR_STACK is https://docs.oracle.com/cd/B19306_01/appdev.102/b14261/errors.htm recommended over SQLERRM, except when using the FORALL statement with its SAVE EXCEPTIONS clause. For more information, see Retrieving the Error Code and Error Message. Syntax sqlerrm_function ::= Description of the illustration sqlerrm_function.gif Keyword and Parameter Descriptions error_number An oracle sql expression whose value is an Oracle Database error number. For a list of Oracle Database error numbers, see 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. oracle sql error 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. 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
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 that it can continue operating in the presence of errors. This chapter contains these topics: Overview of PL/SQL Runtime Error Handling Advantages of PL/SQL Exceptions Summary of 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 Overview of PL/SQL Compile-Time Warnings Overview of PL/SQL Runtime Error Handling In PL/SQL, an error condition is called an exception. 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 enclosing block resumes with the next statement. If there is no enclosing block, control returns to the host environment.
