SQL 查詢 where 子句過濾基於另一列值

Question

下面的查詢我正在嘗試為 team_id>1 過濾 status_id =7 的記錄，但想要為 team_id=1 包含 status_id=7 的記錄。我們如何編寫查詢。

 SELECT MAX(created_date) AS maxtime,
        TEAM_ID,
        ticket_id 
 FROM ri_ticket_status_history  
 WHERE status_id<>7    
 GROUP BY TEAM_ID,ticket_id

Answer 1

and和or邏輯運算符的組合應該這樣做：

SELECT   MAX(created_date) AS maxtime ,team_id, ticket_id 
FROM     ri_ticket_status_history 
WHERE    (status_id <> 7 AND team_id > 1) OR team_id = 1
GROUP BY team_id, ticket_id

Answer 2

嘗試

select max(created_date) as maxtime ,TEAM_ID,ticket_id 
from  ri_ticket_status_history 
where status_id<>7  or  (status_id=7 and team_id=1)
group by TEAM_ID,ticket_id

Answer 3

大括號位置可以改變結果集。

select max(created_date) as maxtime ,TEAM_ID,ticket_id 
from  ri_ticket_status_history 
where ( status_id<>7  or  (status_id=7 and team_id=1))
group by TEAM_ID,ticket_id
