從SQL Server的視圖中獲取當年的記錄

Question

我有一個視圖叫vwMemberPolicyInfo，我需要顯示當前輸入的所有記錄。

我的查詢是：

select 
    EffectiveDate AS [Month], 
    count(MemberID) AS Agents, 
    sum(ActualPremium) AS Premium 
from 
    vwMemberPolicyInfo 
Where 
    EffectiveDate > DATEADD(year, -1, GETDATE()) 
GROUP BY 
    EffectiveDate 

但它不工作正常顯示它的結果：

2010-11-01 00:00:00.000 74 40644.00 
2010-07-01 00:00:00.000 86 50418.00 

2011-03-08 00:00:00.000 1 744.00 
2011-04-08 00:00:00.000 1 0.00 
2010-11-02 00:00:00.000 5 2676.00 

2011-04-14 00:00:00.000 1 1185.00 
2011-02-28 00:00:00.000 7 2988.00 

2011-02-23 00:00:00.000 8 8518.00 
2011-04-10 00:00:00.000 1 1332.00 
2011-04-07 00:00:00.000 3 2544.00 

我只需要本年度項提前顯示..thanks

Answer 1

嘗試where YEAR(EffectiveDate) = YEAR(GETDATE())

希望它有幫助。

Answer 2

它的工作就好了 - 它做正是你告訴它 - 它可以讓你回到那個今天，一年回（如2011年4月15日和2010年4月15日之間）

之間的所有行

你可能想達到什麼是這樣的：

SELECT 
    EffectiveDate AS [Month], 
    COUNT(MemberID) AS Agents, 
    SUM(ActualPremium) AS Premium 
FROM 
    dbo.vwMemberPolicyInfo 
WHERE 
    YEAR(EffectiveDate) = 2011 
GROUP BY 
    EffectiveDate 

這將從今年返回只有行2011年

Answer 3

SELECT MONTH(EffectiveDate) AS [Month], 
     count(MemberID) AS Agents, 
     sum(ActualPremium) AS Premium 
FROM vwMemberPolicyInfo 
WHERE EffectiveDate >= DATEADD(year, YEAR(GETDATE()) - 1, CAST('0001-01-01' AS DATE)) 
     AND EffectiveDate < DATEADD(year, YEAR(GETDATE()), CAST('0001-01-01' AS DATE)) 
GROUP BY 
     MONTH(EffectiveDate) 

Answer 4

選擇
EFFECTIVEDATE AS [月]， 計數（MEMBERID）作爲代理人， 總和（ActualPremium）與Premium 從 vwMemberPolicyInfo 凡 DATEADD（年，0，EFFECTIVEDATE）= DATEADD（年，0，GETDATE （）） GROUP BY EFFECTIVEDATE

dateadd(year,0,EffectiveDate) = DATEADD(year, -1, GETDATE()) 
dateadd(year,-1,EffectiveDate) = DATEADD(year, -1, GETDATE())
