SQL Server如何從日期獲取當前季度的字段計數？

Question

我很難組裝一條SQL語句。場景/要求是這樣的：我需要計算當前季度的場數。

SELECT COUNT(fieldname) AS Hits 
FROM tablename 
WHERE DatePosted = (Current Quarter) 

我想獲得當前季度的點擊次數/次數。

這可能嗎？

Answer 1

select count(fieldname) as Hits 
from tablename 
where datepart(q,DatePosted) = datepart(q,getdate()) 
and year(DatePosted) = year(getdate())
