sql - 使用 SQL Server 2008 从一个表更新到另一个表

Question

我想将数据从一个表更新到另一个具有年份条件的表。

UPDATE pgptrans
SET dcamt1 = t2.ecamt1
FROM pgptrans t1 
INNER JOIN pgptrans060713 t2 ON t1.empcode = t2.empcode 
WHERE       
    t1.empcode LIKE '130%' 
    AND t1.yrmn = '201308' 
    AND t2.yrmn = '201207'

这里更新dcamt表pgptrans（到 201307 年）从ecamt（pgptans060713从年应该是 201308）empcode从 130 开始

请帮我

提前谢谢

使用 INNER JOIN 基于另一个表更新一个表

 UPDATE t1 SET 
        t1.status = 1
 FROM   table1 t1 
        INNER JOIN table t2 
                   ON t1.Id = t2.ID
 WHERE  t2.num = 15
