问题描述

我想使用使用REGEXP的CASE语句.目前,我正在执行以下操作:

I want to use a CASE statement that uses REGEXP. Currently I am doing something like this:

SELECT NAME,
 CASE INFO
   WHEN 'not cool' THEN 'Not Cool'
   WHEN 'very cool' THEN 'Cool'
 ELSE INFO
 END AS INFO
FROM INFO_TABLE

是否可以在初始语句中使用REGEXP来使条件充当REGEXP?从理论上讲,这就是我想要的,这是行不通的:

Is there any way to use REGEXP in the initial statement to make the condition act as a REGEXP? In theory this is what I want, which doesn't work:

SELECT NAME,
 CASE INFO REGEXP
   WHEN 'not cool' THEN 'Not Cool'
   WHEN 'very cool' THEN 'Cool'
 ELSE INFO
 END AS INFO
FROM INFO_TABLE

我希望不酷"和非常酷"成为正则表达式.希望这足够清楚.

I want 'not cool' and 'very cool' to be regular expressions. Hope that is clear enough.

推荐答案

尝试一下

select name,
case
  when info regexp 'not cool' then 'Not Cool'
  when info regexp 'very cool' then 'Cool'
else
  info
end
  as info
from INFO_TABLE;
