SQLCODE function syntax

SQLCODE

The SQLCODE function in SQL has no parameters or arguments.

So exception handling is usually written with the following syntax:

EXCEPTION
WHEN exception_name1_id THEN
[statements]WHEN exception_name2_id THEN
[statements]
WHEN exception_name_n_id THEN
[statements]

WHEN OTHERS THEN
[statements]

END [procedure_name_id];

SQLCODE function to cause an error as follows

EXCEPTION
WHEN OTHERS THEN
raise_application_error(-20001,'An error was encountered - '||SQLCODE|' -ERROR- '||SQLERRM);
END;

You could also save an error record 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;
