ibase_execute
(PHP 5, PHP 7 < 7.4.0)
ibase_execute — Execute a previously prepared query
说明
ibase_execute
( resource $query
, mixed ...$values
) : 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.
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);}?>
