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查询将值存储在DRR中。

Error: Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression. The statement has been terminated.

Answer 1

更换线

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

与

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

当你更新行的列值，则需要提供一个标量值它。
