Question

Hello Stackoverflow成员，

我无法理解如何完成SQL查询。目前我们有两个完成交易的“结账”，然后我们监控每个交易的生产率。然而，最近我们创造了平均结账生产力（每小时）

问题是平均值只是添加两个条目而不是创建平均值。

SQL代码应该如下：

Checkout 1 : 25 transactions 
Checkout 2 : 50 transactions

计算两者之间的平均值（每小时）= / 60 我认为我只能写2除以，显然如果只有一个结账工作，这将把1结账除以2。因此应完成以下内容：如果：只有一笔交易没有分开！

Checkout 1: 25 transactions
checkout 2: 0 transactions

目前我们有一些SQL代码可以一起添加，但不会对数据做任何其他事情。

我理解一个案例陈述会允许我这样做吗？

亲切的问候，莱恩

Answer 1

案例陈述可以检查结账是否已经解雇。

所以尝试这样的事情：

Select 
 case when Checkout1 <> 0 and Checkout2 <> 0 then divide  else dosomthing 
from yourtable

假设结帐结果在表格中

如果输入两个条目，则平均两个条目
