# PDOStatement->errorInfo()

(no version information, might be only in CVS)

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

## 说明

class PDOStatement {
array errorInfo ( void )
}

## 返回值

PDOStatement->errorInfo() returns an array of error information about the last operation performed by this statement 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.

## 范例

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

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

上例将输出：

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