ibase_execute (PHP 3 >= 3.0.6, PHP 4, PHP 5) ibase_execute -- Execute a previously prepared query Descriptionresource 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.
