如何在MySQL中使用正则表达式where where和in语句在where子句中

Question

我有一个查询，我必须从一个表中查看3列，其中我在消息列上搜索了2列，最后一列应该在上面。我怎样才能一次使用两个语句。

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 ;
