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.

例子 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 );
}

?>

注: 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 .
