等同于重复密钥更新的Oracle DB [英] Oracle DB equivalent of on duplicate key update

问题描述

我需要在Oracle中执行以下MySQL查询:

I need to execute the following MySQL-query in Oracle:

INSERT INTO users VALUES(1,10) ON DUPLICATE KEY UPDATE points = 10;

除了merge之外还有其他内容吗?我只是不明白.

Is there something else besides merge? I just don't understand it.

推荐答案

您将需要使用MERGE.像

MERGE INTO users dest
  USING( SELECT 1 user_id, 10 points FROM dual) src
     ON( dest.user_id = src.user_id )
 WHEN MATCHED THEN
   UPDATE SET points = src.points
 WHEN NOT MATCHED THEN
   INSERT( user_id, points ) 
     VALUES( src.user_id, src.points );
