    Today’s article is meant to help you when you get a plsql number SQL error. SQLCODE and even SQLERRM pl/sql are Oracle’s built-in error reporting features. When a new error occurs in PL/SQL, sqlcode returns the number of the last error that occurred. Sqlerrm Each returns a message associated with its subject of the error number.

    This The Oracle Tutorial explains how to use the Oracle/PLSQL SQLERRM function with syntax and examples.

    What Does The Sqlerrm Function Do?

    How do you show errors in PL SQL?

    get error codes and error message: SQLCODE and sqlerrm. In an exception handler, you can use the built-in SQLCODE functions and simply use SQLERRM to find out what error has occurred and get the appropriate error message. Internal SQLCODE exceptions return an Oracle error number.

    SQLERRM, which does all the work for you, returns an error message, the last of which iscontains the error that was thrown. function This should only be used in the exception handling section of your code.

    Syntax

    SQLERRM

    Parameters Or Arguments

    Example

    EXCEPTION   exception-name1 if THEN      [Declaration]   IF exception-name2 THEN      [Declaration]   IF exception_names THEN      [Declaration]   IF THEN other [statements]END [procedure name];

    You can use the SQLERRM role to generate an error like this:

    EXCEPTION   IF THEN others raise_application_error(-20001, 'An error of type '||SQLCODE||' -ERROR- '||SQLERRM);END;

    Or you should log the error to the dinner table using the SQLERRM function like this:

    EXCEPTION   IF THEN other error_code := SQLCODE;      err_msg := SUBSTR(SQLERRM, unique, 200);      INSERT INTO audit_table (error number, error message)      VALUES (error_code, error_message);END;

    Output. In this tutorial, you will learn how to handle additional unhandled exceptions in WHEN OTHER conditions using SQLCODE SQLERRM and .One.

    functions

    In this exception handling section, you can usecall OTHERS clause when to resolve otherwise handled exceptions:



    EXCEPTION ... IF OTHER

    Code language: SQL (Structured Query Language) (sql)

    Because you need to handle other exceptions not listed in the main WHEN OTHERS clause, use built-in error handling functions such as SQLCODE to take advantage of this and therefore , SQLERRM.

    Note that SQLCODE cannot use the SQLERRM function directly in an SQL statement. Instead, you must first define their return values ​​in variables, and then use the variables in the main expression in sql.Function

    Function

    sqlcode

    SQLCODE does not allow arguments to be returned, and the actual code of the most recent exception is numbered.

    If exceptions are internal SQLCODE, the control returns a negative number, except for NO_DATA_FOUND, an exception that has a large number code of +100.

    If an exception is defined returned by the user, SQLCODE +1 or a range you have with an exception using the EXCEPTION_INIT pragma. Related sqlcode Final

    The file can only be used during the exception handling phase. Typically, if you use SQLCODE intent outside of exceptions, the handler will return null.

    What is Raise_application_error in PL SQL?

    The Raise_application_error procedure allows a user-defined error to be generated from a block of function code in a program or a saved program. Using this procedure, you can report errors to callers instead of returning unhandled exceptions.

    EXPLAIN l_code NUMBER; r_customer customers %rowtype;BEGIN SELECT R_customer IN FROM customers; AN EXCEPTION IF OTHERS THEN l_code := SQLCODE; Dbms_output .put_line('Error code:' || l_code);END;/

    Code language: (Structured SQL query (sql)

    In this picture, we are trying to get too many rows in a record, which results in an error with the following error code:

    Error code: -1422

    Code language: (SQL structured query language) (sql)

    Function

    SQLERRM

    Execution of SQLERRM takes an error number as an argument and usually returns the error message associated with that number:

    SQLERRM([error_number])

    Code language: (Structured SQL query (sql)

    In language) this syntax is error_number, of course, any valid oracle error in a court number.

    If you omit the error_number argument, your current function will return the error thoughts associated with the current value of SQLCODE.

    Note that the Not sqlerrm function on the argument is only useful for exception handling.

    sql error number plsql

    This example shows how to use the SQLERRM function found in the exception handler:

    EXPLAIN L_msg VARCHAR2(255); r_customer Rowtype;BEGIN customers % SELECT * INTO r_customer FROM customers; AN EXCEPTION IF OTHERS THEN L_msg SQLERRM; := dbms_output.put_line(l_msg);END;/

    Code language: (Structured SQL query (sql)

    ORA-01422: exact results get more than requested number associated with strings

    Code language: (SQL structured query language) (sql)

    Example Of Using SQLCODE And SQLERRM

    functions

    The implementation example immediately inserts the new contact into the contacts table of the standard database. Custom Is Exception in OTHERS condition where exception in processing section.

    sql error number plsql

    EXPLAIN Contacts l_firstname.firstname%TYPE to: matches 'flor'; contact l_name.:= name%type 'pierre'; L_email contact.email%TYPE:= '[email protected] com'; L_phone contact.phone%TYPE := '+1 317 123 4105'; associated l_kunden_id.kunden_id%TYP := -1;BEGIN ADD TO CONTACTS (name, surname, email, phone, customer number) VALUES(l_firstname, l_lastname, l_email, l_phone, l_customerid); AN EXCEPTION IF OTHERS THEN EXPLAIN l_error PLS_INTEGER := SQLCODE; l_msg VARCHAR2(255):= sqlerrm; BEGIN CAS l_error IF -1 THEN
