MySql 删除语句 DELETE
语法： delete from 表名称 where 删除条件注意： 如果没有设定删除条件，该表内容鬼都不剩！例：
mysql> use RUNOOB;
Database changed
mysql> DELETE FROM runoob_tbl WHERE runoob_id=3;
Query OK, 1 row affected (0.23 sec)
在PHP中：依旧用mysqli_query() 函数来执行，贴代码啦
<?php
$dbhost = 'localhost:3306';// mysql服务器主机地址
$dbuser = 'root'; // mysql用户名
$dbpass = '123456'; // mysql用户名密码
$conn = mysqli_connect($dbhost, $dbuser, $dbpass);
if(! $conn )
{
die('连接失败: ' . mysqli_error($conn));
}
// 设置编码，防止中文乱码
mysqli_query($conn , "set names utf8");
$sql = 'DELETE FROM runoob_tbl
WHERE runoob_id=3
mysqli_select_db( $conn, 'RUNOOB' );
$retval = mysqli_query( $conn, $sql );
if(! $retval )
{
die('无法删除数据: ' . mysqli_error($conn));
}
echo '数据删除成功！mysqli_close($conn);
?>
