PDOStatement::errorInfo Obtiene información ampliada del error asociado con la última operación del gestor de sentencia


public PDOStatement::errorInfo(): array

Valores devueltos

PDOStatement::errorInfo() devuelve un array con la información de error de la última operación realizada por este gestor de sentencia. El array consiste en los siguiente campos:

Elemento Información
0 Código de error de SQLSTATE (un identificador alfanumérico de cinco caracteres definido en el estándar ANSI SQL).
1 Código de error específico del controlador.
2 Mensaje de error específico del controlador.


Ejemplo #1 Mostrar los campos de errorInfo() para una conexión PDO_ODBC a una base de datos de DB2

/* Provocar un error -- la tabla BONES no existe */
$gsent = $gbd->prepare('SELECT skull FROM bones');

$arr = $gsent->errorInfo();

El resultado del ejemplo sería:

    [0] => 42S02
    [1] => -204
    [2] => [IBM][CLI Driver][DB2/LINUX] SQL0204N  "DANIELS.BONES" is an undefined name.  SQLSTATE=42704

Seriously errorInfo is your friend. Use it.

If these look like your google searches then you need errorInfo

"no database error showing in php"
"pdo selects from database but wont insert"
"pdo insert not working"
"isnt pdo just a big hype, should I go back to mysql?"
"how much do surgeons make?"

Trust me it will definitely save you hours of insanity if you make it a habit to use it in development. Forget E-ALL, it failed me since well, E-ALL apparently doesn't know that I didn't set a default value in my MySQL table and my query wasnt adding anything to it. So always do this


= 'do something on a mysql table where foo = :bar';
$stmt = prepare($sql);
$stmt->bindValue(':bar', $foo, PDO::PARAM_[DATA TYPE]);

// very important during development. But take it off in production
$foo_arr = $stmt->errorInfo();

//Sample print_r return
[0] => HY000
[1] => 1364
[2] => Field 'phone' doesn't have a default value
Never have I been so happy to see an error

While its common practice for any decent developer to always watch out and try to catch for errors, even the best of us make mistakes. This is not a replacement for exceptions, but the simplicity is priceless.

If your query is successful, PDO::errorInfo() still returns an array. For MySQL 5.x, I get the following...

[0] => 00000
[1] =>
[2] =>

Sorry, my example below is not correct, this is a correction:

= $db->query('SELECT name from uesrs');
$errorInfo = $listOfUsers->errorInfo();
$errorInfo[0] != 0)
