mysql - 如何在 MySQL where like 和 where 子句中的语句中使用正则表达式

Question

我有一个查询，我必须从一个表中查看 3 列，其中我在 message 列上搜索了 2 列，最后一列应该在 like 上。我怎样才能同时使用这两个语句。

SELECT   date(datetime) as dateonly ,
sum(CASE message when 'Accepted Images' then 1 else 0 end) as AcceptedIMG,
sum(CASE message when 'Rejected Images' then 1 else 0 end) as RejectedIMG,
sum(CASE when message like '%Changed  to %'    then 1 else 0 end) as ChangeIMG
FROM customer_1.audit_trail 
WHERE  message  like ('%Changed  to %') and message in ('Accepted Images','Rejected Images') 
GROUP BY (dateonly)
ORDER BY (dateonly) asc ;

Answer 1

您可以使用 OR （并将您的条件分组）

SELECT   date(datetime) as dateonly ,
sum(CASE message when 'Accepted Images' then 1 else 0 end) as AcceptedIMG,
sum(CASE message when 'Rejected Images' then 1 else 0 end) as RejectedIMG,
sum(CASE when message like '%Changed  to %'    then 1 else 0 end) as ChangeIMG
FROM customer_1.audit_trail 
WHERE  (message  like ('%Changed  to %') OR message in ('Accepted Images','Rejected Images')) 
GROUP BY (dateonly)
ORDER BY (dateonly) asc ;
