sql中两个和的最大总和

Question

我有桌子:

Bonus     Value

500       1400

1500       177

1800       453

1200       100

800       2500

200         50

780        740

我想打印列的总和,以最大值为准.

我试过以下:

select 
case when sum(bonus)>sum(Value) then sum(bonus) end
case when sum(Value)>sum(bonus) then sum(Value) end
from emp

但我没有得到结果.

错误:

Msg 156, Level 15, State 1, Line 3
Incorrect syntax near the keyword 'case'.

Answer 1

您的语法不正确,CASE关键字只出现一次:

select 
  case when sum(bonus)>sum(Value) then sum(bonus)
     else sum(Value) 
  end as MaxSum
from emp
