Question

我正在尝试编写要在MySQL中删除的行。

我不知道如何做到这一点所以从其他网站上选择了一些代码：

语法：

<?php
$personID=$_GET["q"];
if ($personID<="0"){echo( "<center><h3><a href=\"#\" onclick=\"window.close(); return false\">NO ID ERROR CLICK THIS TO RETRY CLOSE WINDOW</a></h3></center>"); 
 }
 else
 {
 $con = mysql_connect("mysql.XXX.com","XXX","XXX");

if (!$con) 
  {
   die('Could not connect: ' . mysql_error());
   }
  $myid=$_COOKIE["user"];

@mysql_select_db("u716720408_admin", $con)or die( "Unable to select database");
$result=mysql_query("DELETE * FROM users WHERE personID=$personID")or die(mysql_error());  

$cnt=1;

$row = mysql_fetch_array( $result );

$f1=$row['personID'];
$f2=$row['personFname'];
$f9=$row['llmail'];
$f14=$row['personSname'];
$f19=$row['password']; 

?>

Answer 1

使用：

 DELETE FROM users WHERE personID=$personID

请务必阅读SQL Injection

Answer 2

删除查询中不需要*

试

DELETE FROM users WHERE personID=$personID

Answer 3

在您的搜索结果中，您无需在删除查询

中提及*

$result = mysql_query("DELETE FROM users WHERE personID=$personID") or
     die(mysql_error());

使用MySQL从表中删除整行
