仅显示特定行，php脚本或sql查询

Question

我有一张这样的表

id     tran_id     event_name
1      55262       activate
2      55262       suspended
3      47282       approval

如果发现event_name等于＆＃39;激活＆＃39;不要显示具有相同tran_id的所有数据

我试图使用sql-script获取此功能，但我认为它应该使用php脚本

Answer 1

SELECT *
FROM yourTable
WHERE tran_id NOT IN (
    SELECT tran_id 
    FROM yourTable 
    WHERE event_name = 'activate')

或

SELECT a.*
FROM yourTable AS a
LEFT JOIN yourTable AS b ON a.tran_id = b.tran_id AND b.event_name = 'activate'
WHERE b.tran_id IS NULL
