JobPost_Skill

JobPost_Skill_ID    JobPost_ID  Skill_ID     
 -----------        -----------  -----------
      1                1             1
      2                1             2

      5                2             5

这是我的第三个表，其中JobPost_ID，Skill_ID是外键 现在我想更新查询，它只会更新JobPost_ID = 1的两行Skill_ID。

这意味着我的输出应该是

JobPost_Skill_ID    JobPost_ID  Skill_ID     
 -----------        -----------  -----------
      1                1             4
      2                1             5
      3                1             3
      4                2             3
      5                2             5

Answer 1

您可以使用以下查询进行更新

updete JobPost_Skill 
set Skill_ID =New Skill_ID 
where JobPost_ID=JobPost_ID  
and Skill_ID = oldSkill_ID

注意：替换

JobPost_ID您需要更新的职位发布ID

技能ID的新Skill_ID新值

oldSkill_ID技能ID的旧值

<强>即

       updete JobPost_Skill set Skill_ID = 4 where JobPost_ID=1 and Skill_ID = 1;

        updete JobPost_Skill set Skill_ID = 5 where JobPost_ID=1 and Skill_ID = 2,
