Mysql切除单列两栏。
原标题:Mysql delete query deletes only two columns in a row

我有一个表格,其结构如下:

    FIELD           TYPE          EXTRA
faciltiy_id         int          auto_increment(Primary Key)
hotel_id            int
facility_title      varchar(20)
facility_desc      varchar(300)

当我想要删除一条有特定内容的句子时,法系_id 我使用该守则,

DELETE 
FROM   $hotel_facilities
WHERE  facilities_id =  $facilities_id ";

但并非整个行文,而是只有<条码>。 这些领域正在删除。 如果我直接通过Sandomyadmin处理这一询问,那是正确的。

谁能向我介绍一下什么是错了?

最佳回答

但是,只有设施——产权和设施——种子田被删除,而不是整个行。 如果我直截了当地人手,那就正确了......。

由于<代码>facilities_id 您是一位国际专家,无需在一书中附上:

DELETE FROM {$hotel_facilities}
 WHERE facilities_id = {$facilities_id}

但我认为,真正的问题是,正在要求发表一项统一声明,而不是宣布独立党的声明。 主要由于DELETE声明只删除整段,而不是具体栏目。

在执行之前,你需要追踪所要求提交材料的情况,并打印在(使用<条码>echo<>/条码>上,或者在越方便的情况下通过Javascript进行)。
