ibase_execute

(PHP 5, PHP 7)

ibase_execute — Execute a previously prepared query

说明

ibase_execute ( resource $query [, mixed $... ] ) : resource

Execute a query prepared by ibase_prepare().

This is a lot more effective than using ibase_query() if you are repeating a same kind of query several times with only some parameters changing.

参数

query: An InterBase query prepared by ibase_prepare().
...

返回值

If the query raises an error, returns FALSE. If it is successful and there is a (possibly empty) result set (such as with a SELECT query), returns a result identifier. If the query was successful and there were no results, returns TRUE.

Note:

This function returns the number of rows affected by the query (if > 0 and applicable to the statement type). A query that succeeded, but did not affect any rows (e.g. an UPDATE of a non-existent record) will return TRUE.

范例

Example #1 ibase_execute() example

 <?php

$dbh = ibase_connect($host, $username, $password);

$updates = array(
    1 => 'Eric',
    5 => 'Filip',
    7 => 'Larry'
);

$query = ibase_prepare($dbh, "UPDATE FOO SET BAR = ? WHERE BAZ = ?");

foreach ($updates as $baz => $bar) {
    ibase_execute($query, $bar, $baz);
}

?>
