如何在MySQL where和where子句中的語句中使用正則表達式

Question

我有一個查詢，我必須從一個表中查找3列，在該表中我在message列上搜索了2列，最后一列應該在like上。 我如何一次使用兩個語句。

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（並分組您的條件）

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 ;
