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
/* Provoke an error -- bogus SQL syntax */
$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
)
