# PDO::errorInfo

(PHP 5 >= 5.1.0, PECL pdo >= 0.1.0)

PDO::errorInfo — Fetch extended error information associated with the last operation on the database handle

### 설명

array PDO::errorInfo ( void )

### 반환값

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 characters alphanumeric identifier defined in the ANSI SQL standard).
1 | Driver-specific error code.
2 | Driver-specific error message.

> Note: If the SQLSTATE error code is not set or there is no driver-specific error, the elements following element 0 will be set to `NULL`.

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.

### 예제

Example #1 Displaying errorInfo() fields for a PDO_ODBC connection to a DB2 database

`<?php
/* Provoke an error -- bogus SQL syntax */
$stmt = $dbh->prepare('bogus sql');
if (!$stmt) {
echo "\nPDO::errorInfo():\n";
print_r($dbh->errorInfo());
}
?>`

위 예제의 출력:

    PDO::errorInfo():
    Array
    (
        [0] => HY000
        [1] => 1
        [2] => near "bogus": syntax error
    )
