比较一个列与另一列相似的列 [英] Compare Columns Where One is Similar to Part of Another

问题描述

我正在尝试编写一个 Select 语句，我可以在其中查看一列是否与另一列相似.

I'm trying to write a Select statement where I can see if one column is like part of another.

tblNames 
ID    FullName                   FirstName
1     Mr. John Doe, CEO          John
2     Mr. Jake Doe, Exec        Jake
3     Mrs. Betty Smith, Chair     Jill

查询应该返回:

3 | Mrs.Betty Smith, Chair | Jill

但是我的只是返回表中的每一行:

However mine just returns every row in the table:

SELECT ID, FullName, FirstName
FROM tblNames
WHERE '%' + FirstName + '%' not like Fullname

有什么想法吗?

推荐答案

将 where 反转成这样:

Reverse the where, to something like this:

Fullname not like '%' + FirstName + '%'
