php - 数据库中的未知列问题

Question

请帮我解决我遇到的这个问题。我在 'where 子句' 中得到 '未知列 'the_mother_church_id' 。 我已经多次检查数据库中的列名的名称，并且我确定名称是相同的。

请问问题出在哪里。

谢谢

<?php
   $past = mysql_query("SELECT * FROM the_mother_church WHERE the_mother_church_id = '1'") or die(mysql_error()); 
?>

创建表

CREATE TABLE IF NOT EXISTS `the_mother_church` (
  ` the_mother_church_id` int(255) NOT NULL,
  `the_mother_church_head` varchar(255) NOT NULL,
  ` the_mother_church_content` varchar(3000) NOT NULL,
  ` the_mother_church_tags` varchar(255) NOT NULL,
  ` the_mother_church_created` datetime NOT NULL,
  ` the_mother_church_image` blob NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

(升级到答案)

您的 CREATE TABLE 语句显示该列的命名方式在起始引号和字段名称之间有一个空格:` the_mother_church_id`。要么:

1. 在查询中使用带有空格的列名称:

   SELECT * FROM the_mother_church WHERE ` the_mother_church_id` = '1'
   

2. 重命名列:

   ALTER TABLE `the_mother_church`
     CHANGE ` the_mother_church_id`
             `the_mother_church_id`      int(255)      NOT NULL,
     CHANGE ` the_mother_church_content`
             `the_mother_church_content` varchar(3000) NOT NULL,
     CHANGE ` the_mother_church_tags`
             `the_mother_church_tags`    varchar(255)  NOT NULL,
     CHANGE ` the_mother_church_created`
             `the_mother_church_created` datetime      NOT NULL,
     CHANGE ` the_mother_church_image`
             `the_mother_church_image`   blob          NOT NULL;
