分组依据在SQL中没有给出适当的计数

Question

在上一篇文章中，我像这样在temp表中获取了所有数据

select * from #MyTempEmployeeTable

数据：

version     count1  productname

我正在编写以下查询，以按版本对分组进行计数，但它没有返回预期的结果。

select count(count1), version   
from #MyTempEmployeeTable 
group by version

运行此查询后，我没有得到适当的数据

(No column name)    version
------------------------------
3   10.0
8   10.0.1
4   10.0.14
4   10.0.15
1   10.0.18
1   7.4.76
1   7.5.7601
2   7.6.76
5   7.6.7601
2   7.8.9200
8   7.9.9600

能帮我一下吗？对于10.0版，理想情况下，我应该将数据作为496

Answer 1

您要sum()，而不是count()：

select sum(count1), version
from #MyTempEmployeeTable
group by version

Answer 2

我认为您不希望sum()不计算

select sum (count1),version   
from #MyTempEmployeeTable group by version

Answer 3

我认为您需要使用SUM

select sum(count1),
  version 
from #MyTempEmployeeTable 
group by version

count是行数，sum是列中值的总和。

，对于10.0版，您将获得498（486 + 10 + 2），而不是问题中的496。
