ibase_execute
IBASE_EXECUTE(3) 1 IBASE_EXECUTE(3)
ibase_execute - Execute a previously prepared query
SYNOPSIS
resource ibase_execute (resource $query, [mixed $bind_arg], [mixed $...])
DESCRIPTION
Execute a query prepared by ibase_prepare(3).
This is a lot more effective than using ibase_query(3) if you are repeating a same kind of query several times with only some parameters
changing.
PARAMETERS
o $query
- An InterBase query prepared by ibase_prepare(3).
o $bind_arg
-
o $...
-
RETURN VALUES
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 suc-
ceeded, but did not affect any rows (e.g. an UPDATE of a non-existent record) will return TRUE.
EXAMPLES
Example #1
ibase_execute(3) 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);
}
?>
