Wyjątki

Tabela 35-1. Możliwe wartości PEAR_Error

Error codeError messageReasonSolution
DB_ERROR_INVALID invalid SQL statment handle is not valid. Check correct processing of the SQL statment with prepare(). Note that execute() requires a handle to the statement returned by prepare(), not the statment itself.
DB_ERROR_MISMATCH mismatch Quantity of parameters didn't match quantity of placeholders in the prepared statment. Check that the number of placeholders in the prepare() statement passed to $query equals the count of entries passed to $params.
DB_ERROR_NODBSELECTED no database selected No database was choosen. Check the DSN in connect().
every other error code  Database specific error Check the database related section of PHP-Manual to detect the reason for this error. In the most cases a misformed SQL statment. Ie. using LIMIT in a SQL-Statment for an Oracle database.

Uwagi

Ta funkcja nie może być wywołana statycznie.

Ostrzeżenie

The values passed in $data must be literals. Do not submit SQL functions (for example CURDATE()). SQL functions that should be performed at execution time need to be put in the prepared statement.

Przykład

Przykład 35-1. Passing a scalar to execute()

<?php
// Once you have a valid DB object named $db...
$sth = $db->prepare('INSERT INTO numbers (number) VALUES (?)');
if (PEAR::isError($sth)) {
    die($sth->getMessage());
}

$res =& $db->execute($sth, 1);
if (PEAR::isError($res)) {
    die($res->getMessage());
}
?>

Przykład 35-2. Passing an array to execute()

<?php
// Once you have a valid DB object named $db...
$sth = $db->prepare('INSERT INTO numbers VALUES (?, ?, ?)');

$data = array(1, 'one', 'en');
$db->execute($sth, $data);
?>
