# 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.

### 参数

`query`
  An InterBase query prepared by ibase_prepare().
`values`

### 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`.

> 注意: 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`.

### 示例

示例 #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);
}
?>`
