# PDO->errorInfo()

(no version information, might be only in CVS)

PDO->errorInfo() -- Fetch extended error information associated with the last operation on the database handle

## Описание

class PDO {
array errorInfo ( void )
}

## Возвращаемые значения

PDO->errorInfo() returns an array of error information about the last operation performed by this database handle. The array consists of the following fields:

Element | Information
--- | ---
0 | SQLSTATE error code (a five-character alphanumeric identifier defined in the ANSI SQL standard).
1 | Driver-specific error code.
2 | Driver-specific error message.

PDO->errorInfo() only retrieves error information for operations performed directly on the database handle. If you create a PDOStatement object through PDO->prepare() or PDO->query() and invoke an error on the statement handle, PDO->errorInfo() will not reflect the error from the statement handle. You must call PDOStatement->errorInfo() to return the error information for an operation performed on a particular statement handle.

## Примеры

Пример 1. Displaying errorInfo() fields for a PDO_ODBC connection to a DB2 database

`<?php
/* Provoke an error -- the BONES table does not exist */
$err = $dbh->prepare('SELECT skull FROM bones');
$err->execute();
echo "\nPDO::errorInfo():\n";
print_r($err->errorInfo());
?>`

Результат выполнения данного примера:

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

`The example code is incorrect. The line that reads:
$err = $dbh->prepare('SELECT skull FROM bones');
Will set the value of $err to be boolean FALSE.
So, to get a useful error dump change this line:
print_r($err->errorInfo());
to:
print_r($dbh->errorInfo());`
