和

Declare @year int
Set @year = 2014

select 
   a.first_name, a.last_name,
   Count(case when Month(b.funded_date) = 1 Then 1 else Null End) Janurary, 
   Count(case when Month(b.funded_date) = 2 Then 1 else Null End) Feburary ,
   Count(case when Month(b.funded_date) = 3 Then 1 else Null End) March,
   Count(case when Month(b.funded_date) = 4 Then 1 else Null End) April
from 
   tContact a 
Inner join 
   tContract b On a.contact_id = b.contract_id
Group by 
   first_name, last_name

Answer 1

假设SQL Server（基于语法），您可以执行以下操作：

select a.first_name + a.last_name,
       sum(case when Month(b.funded_date) = 1 Then 1 else 0 End) Janurary, 
       sum(case when Month(b.funded_date) = 2 Then 1 else 0 End) Feburary ,
       sum(case when Month(b.funded_date) = 3 Then 1 else 0 End) March,
       sum(case when Month(b.funded_date) = 4 Then 1 else 0 End) April,
       sum(case when Month(b.funded_date) <= 4 then 1 else 0 end) as YTD
from tContact a Inner join
     tContract b
     On a.contact_id = b.contract_id
Group by first_name + last_name with rollup;

如果您有多个group by列，并且只需要一个摘要，请查看GROUPING SETS。
