DB_common::executeMultiple()

DB_common::executeMultiple() -- Runs a prepared SQL statment for each element of an array

Synopsis

integer executeMultiple (resource $stmt, array $data)

Описание

Automatically passes the information in $data (a multi-dimensional array) to execute(), which then runs the SQL statment you submitted to prepare().

Параметр

resource $stmt: query handle from prepare()
array $data: a numeric array containing the data to insert into the query

Возвращаемое значение

integer - DB_OK on success or a DB_Error object on failure

Throws

Таблица 34-1. Возможные значения PEAR_Error

Error code	Error message	Reason	Solution
`DB_ERROR_INVALID`	invalid	SQL statment handle is not valid.	Check correct processing of the SQL statment with prepare(). Note that executeMultiple() 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.

Заметка

Эта функция не должна вызываться статически.

Внимание

If an error occurs during execution, the function will be stopped. Possible remaining data will be unprocessed.

Внимание

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.

Пример

Пример 34-1. Using executeMultiple()

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

if (PEAR::isError($sth)) {
    die($sth->getMessage());
}

$alldata = array(array(1, 'one', 'en'),
                 array(2, 'two', 'to'),
                 array(3, 'three', 'tre'),
                 array(4, 'four', 'fire'));

$res =& $db->executeMultiple($sth, $alldata);

if (PEAR::isError($res)) {
    die($res->getMessage());
}
?>
