使用select语句更新查询

Question

update DCC set DRR=
    (select cast((CAST((SUM(EMI)/100) AS DECIMAL(2,2))+CAST((SUM([REPO ARREAR])/100) AS DECIMAL(2,2))) as decimal(2,2))/((TOTAL*35)/100)/0.01 
    from dcc  
    where (CURR_DATE  BETWEEN '2014-01-01' and '2014-01-03') 
    GROUP BY TOTAL )

这是我的查询我必须使用select query将值存储在DRR中。

  

错误：子查询返回的值超过1。当子查询遵循=，！=，＆lt;，＆lt; =，＆gt;，＆gt; =或子查询用作表达式时，不允许这样做。   声明已经终止。

Answer 1

替换

行

select cast((CAST((SUM(EMI)/100) AS DECIMAL(2,2)

带

select TOP 1 cast((CAST((SUM(EMI)/100) AS DECIMAL(2,2)

更新行的列值时，需要为其提供单个标量值。
