在MySQL UPDATE(PHP/MySQL)中使用变量

问题描述:

我正在使用此代码,因此我可以更新数据库中的记录:

I am using this code so I can update a record in database:

$query = mysql_query("UPDATE article 
                         SET com_count = ". $comments_count 
                       WHERE article_id = .$art_id ");

我的问题是:如何在MySQL UPDATE语句中使用变量.

My question is: How can I use variables in a MySQL UPDATE statement.

$query = mysql_query("UPDATE article set com_count = $comments_count WHERE article_id = $art_id");

您正在弄乱报价和连载.

You was messing up the quotes and concats.

您可以像前面的示例一样使用内联var或像这样连接它们:

You can use inline vars like the previous example or concat them like:

$query = mysql_query("UPDATE article set com_count = " . $comments_count . " WHERE article_id = " . $art_id);
