This Oracle tutorial explains how to use the Oracle/PLSQL SQLCODE function with syntax and examples.

What does the SQLCODE Function do?

The SQLCODE function returns the error number 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 SQLCODE function in Oracle/PLSQL is:

SQLCODE

Parameters or Arguments

There are no parameters or arguments for the SQLCODE function.

Note

  • See also the SQLERRM 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 SQLCODE 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 SQLCODE 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;
