Question

我想创建一个存储过程，可以过滤日期范围。我想显示分组，没有日期我的数据。在某些时期，SUM每个员工的前景如何访问。

现在我有了这个，但还不够好。我应该删除av.Date，但没有av.Date，我无法过滤我的日期范围！

Select emp.Name+' '+emp.Surname as TaskOwner,av.Date,et.Event,COUNT(av.EventTypeID) as something
from TableT av
left join Employee emp on av.CreatedBy = emp.EmployeeD
left join EventType et on av.EventTypeID = et.EventTypeID
Group By av.Date, et.Event, emp.Name+' '+emp.Surname
Order By TaskOwner desc

我当前的输出就像

John Doe    2016-03-02  PROPOSALS ACCEPTED  1
John Doe    2016-03-04  PROSPECTS VISITS    2
John Doe    2016-03-07  COMMERCIAL VISITS   1
John Doe    2016-03-08  PROPOSALS MADE          1
John Doe    2016-03-13  PROPOSALS ACCEPTED  1
Someone Else    2016-01-04  PROPOSALS MADE          1
Someone Else    2016-03-03  COMMERCIAL VISITS   1
Someone Else    2016-03-04  PROPOSALS ACCEPTED  1
Someone Else    2016-03-06  PROPOSALS ACCEPTED  1

我需要的是这样的事情：

John Doe        PROPOSALS ACCEPTED  2
John Doe        PROSPECTS VISITS    2
John Doe        COMMERCIAL VISITS   1
John Doe        PROPOSALS MADE      1
Someone Else    PROPOSALS MADE      1
Someone Else    COMMERCIAL VISITS   1
Someone Else    PROPOSALS ACCEPTED  2

但是能够过滤日期范围。

Answer 1

您可以尝试以下查询

Select 
  emp.Name+' '+emp.Surname as TaskOwner,
  et.Event,
  COUNT(av.EventTypeID) as something
from TableT av
  left join Employee emp on av.CreatedBy = emp.EmployeeD
  left join EventType et on av.EventTypeID = et.EventTypeID
Where 
  (ISNULL (@lowerdate) OR av.Date >= ISNULL(CAST(@lowerdate as datetime))
  AND 
  (ISNULL (@higherdate ) OR av.Date <= CAST(@higherdate as datetime) )
 -- this is how we filter, assuming you get two dates always and also taking care of NULL
Group By et.Event, emp.Name+' '+emp.Surname
Order By TaskOwner desc

SQL查询汇总每个员工的项目 - 日期范围
