PDO::errorInfo — Fetch extended error information associated with the last operation on the database handle
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.
Example #1 Displaying errorInfo() fields for a PDO_ODBC connection to a DB2 database
<?php
$stmt = $dbh -> prepare ( 'bogus sql' );
if (! $stmt ) {
echo "\nPDO::errorInfo():\n" ;
print_r ( $dbh -> errorInfo ());
}
?>
以上例程会输出:
PDO::errorInfo(): Array ( [0] => HY000 [1] => 1 [2] => near "bogus": syntax error )

I don't know why mazen at mindcraftinc dot com is getting that amount of negative votes: in my case, I've constated that with odbc_driver and an Access database, this method is returning ONE extra field appart from what is stated in this manual.
More precisely, if using the PDO odbc_pdo driver with an Access database, in a fourth array element I'm getting the ODBC Status Return Code.

Please note : that this example won't work if PDO::ATTR_EMULATE_PREPARES is true.
You should set it to false
<?php
$dbh->setAttribute(PDO::ATTR_EMULATE_PREPARES,false);
$stmt = $dbh->prepare('bogus sql');
if (!$stmt) {
echo "\nPDO::errorInfo():\n";
print_r($dbh->errorInfo());
}
?>

Some PDO drivers return a larger array. For example, the SQL Server driver returns 5 values.
For example:
<?php
$numRows = $db->exec("DELETE FROM [TableName] WHERE ID between 6 and 17");
print_r($db->errorInfo());
?>
Result:
Array
(
[0] => 00000
[1] => 0
[2] => (null) [0] (severity 0) []
[3] => 0
[4] => 0
)

here is a reference to the ansi error codes
there are several others;
a link to the official spec from ansi would be nice
(have to rebuild this link because its too long to post w/o breaking it up)
