Varoitus

Varoitus! T�m� funktio on EKSPERIMENTAALINEN. T�m�n funktion ominaisuudet, k�ytt�ytyminen, parametrit ja nimi voi muuttua varoituksetta seuraavissa PHP:n versioissa.

Return values

Returns a SQLSTATE, a five-character alphanumeric identifier defined in the ANSI SQL standard.

PDO::errorCode() only retrieves error codes 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::errorCode() will return PDO_ERR_NONE. You must call PDOStatement::errorCode() to return the error code for an operation performed on a particular statement handle.

Examples

Esimerkki 1. Retrieving a SQLSTATE code

<?php
/* Provoke an error -- the BONES table does not exist */
$dbh->exec("INSERT INTO bones(skull) VALUES ('lucy')");

echo
"\nPDO::errorCode(): ";
print
$dbh->errorCode();
?>

The above example will output:

PDO::errorCode(): 42S02
