ibase_execute

(PHP 3 >= 3.0.6, PHP 4, PHP 5)

ibase_execute -- Execute a previously prepared query

Description

resource ibase_execute ( resource query [, mixed bind_arg [, mixed ...]] )

Execute a query prepared by ibase_prepare(). 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.

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.

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 = ?");

while (list($baz, $bar) = each($updates)) {
    ibase_execute($query, $bar, $baz);
}

?>

Note: In PHP 5.0.0 and up, 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.
