这样能行吗?没怎么用过批量操作数据库,请指导。

###代码大概像这样吧,手打的,没有测试###
<code>php</code><code>$sql = 'INSERT INTO TABLE (`u_uid`, `userid`,`status`,`confirm_time`,`pv_total`) VALUES'; foreach($arr as $k => $item) { $sql .= '(' . $item['u_uid'] . ',' . $item['userid'] . ',' . $item['status'] . ',' . $item['confirm_time'] . ',' . $item['pv_total'] . '),'; } $sql = rtrim($sql, ','); </code>
对,就是这样的。
<code>sql</code><code>INSERT INTO table_name (列1, 列2,...) VALUES (值1, 值2,....),(值1, 值2,....),(值1, 值2,....) </code>
