我有三张桌子:
1)participant
***********
+id_participant
+id_poste
+name
+email
2) profile_formaion
****************
+id_poste
+id_formation
3) formation
*********
+id_formation
+lable
EXAMPLE:
数据:参与者
1 | 2 | user1 | [email protected]
资料图:剖面图
2 | 3
2 | 4
资料:编队
1 |lable1
2 |lable2
3 |lable3
4 |lable4
任何人都可以帮助我如何使用sql语句(join)获得结果:
数据:结果
1 | 2 | user1 | [email protected] | label3
1 | 2 | user1 | [email protected] | label4
谢谢
最佳答案
SELECT
participant.id_participant,
participant.id_poste,
participant.name,
participant.email,
formation.lable
FROM participant
INNER JOIN profile_formaion ON
profile_formaion.id_poste = participant.id_poste
INNER JOIN formation ON
formation.id_formation = profile_formaion.id_formation
