Question

我正在尝试从Wordpress中选择SELECT（所有多个）与GROUP_CONCAT相关的帖子（wp_comments.comment_content），但我只想选择那些不包含文本字符串“status”的注释。如果根本没有评论，或者只有包含“状态”的评论，我仍然希望在结果中看到这些记录，只是没有得到任何回复评论。

当我在完整查询结束时尝试设置类似于[WHERE wp_comments.comment_content NOT LIKE“％status％”]的条件时，只有包含“status”的注释的记录不显示AT ALL，I仍然需要获取这些记录，只是没有评论。

我想尝试类似以下版本的内容，但这会引发错误并且根本不会吐出任何数据。（除了注释选择部分之外，整体查询按预期工作。）。

也许我在错误的地方加入了wp_comments表，使用了错误的连接，没有使用格式正确的嵌套SELECT或类似的东西，也许它最后需要一个单独的SELECT所以我可以在这种方式不会影响整体选择哪些记录..不确定..

知道我做错了什么或如何解决这个问题？

这是我的查询，提前感谢任何类型的指针！

这有效
