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

说明

array PDO::errorInfo ( void )

返回值

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.

范例

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
)

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 are the error codes for sqlite, straight from their site:

#define SQLITE_LOCKED       6   /* A table in the database is locked */
#define SQLITE_NOMEM        7   /* A malloc() failed */
#define SQLITE_READONLY     8   /* Attempt to write a readonly database */
#define SQLITE_INTERRUPT    9   /* Operation terminated by sqlite_interrupt() */

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)

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());
