Question

我目前有一个asp.net页面，它接收来自此视图的数据，并根据它将更改金额字段文本的百分比。这意味着如果用户达到某个百分比，他们就会获得一定的激励金额。

但是，我目前正在我的程序中执行此操作，但出于报告目的，我希望能够直接在sql中执行此操作，而不是在我的asp.net页面中执行此操作。

我想做的几乎就是   如果百分比列=   65％到70％然后金额列=   如果百分比列= 70到75，则为50   百分数然后数量列= 75

直接在我的数据视图中而不是在我的数据视图中   asp.net页面

If Decimal.Parse(percent.Text) >= 0.65 And percent.Text < 0.7 Then
                Amount.Text = 50
            ElseIf Decimal.Parse(percent.Text) >= 0.7 And percent.Text < 0.75 Then
                Amount.Text = 75
            ElseIf Decimal.Parse(percent.Text) >= 0.75 And percent.Text < 0.8 Then
                Amount.Text = 200
            ElseIf Decimal.Parse(percent.Text) >= 0.8 And percent.Text < 0.85 Then
                Amount.Text = 500
            ElseIf Decimal.Parse(percent.Text) >= 0.85 And percent.Text < 0.9 Then
                Amount.Text = 625
            ElseIf Decimal.Parse(percent.Text) >= 0.9 And percent.Text < 0.95 Then
                Amount.Text = 750
            ElseIf Decimal.Parse(percent.Text) >= 0.95 And percent.Text < 1.0 Then
                Amount.Text = 1000

这是我的查看查询，我几乎想添加一个if语句，但我不确定这是否是最好的方法。

SELECT     TOP (100) PERCENT SUM(yes) AS Countreported, SUM(no) AS Countnotreported, SUM(yes) + SUM(no) AS count, BMM, BYYYY, userid, SUM(pax) 
                          AS party, CAST(SUM(yes) AS decimal(4, 1)) / (SUM(yes) + SUM(no)) AS percentage
    FROM         (SELECT     SUM(CASE WHEN [insreported] IS NULL THEN 0 WHEN [insreported] = 'YES' THEN 1 ELSE 0 END) AS yes, 
                                                  SUM(CASE WHEN [insreported] IS NULL THEN 1 WHEN [insreported] = 'YES' THEN 0 ELSE 1 END) AS no, CASE WHEN USERID = 'chrisn' OR
                                                  USERID = 'CHRISN' THEN 'chrism' ELSE USERID END AS userid, dbo.agent_insurance_incentive_data.BMM, 
                                                  dbo.agent_insurance_incentive_data.BYYYY, SUM(dbo.agent_insurance_incentive_data.PARTY) AS pax, 
                                                  dbo.incentive_agents.department
                           FROM          dbo.agent_insurance_incentive_data LEFT OUTER JOIN
                                                  dbo.incentive_agents ON dbo.agent_insurance_incentive_data.USERID = dbo.incentive_agents.agent
                           WHERE      (dbo.agent_insurance_incentive_data.DYYYY >= '2009') AND (dbo.agent_insurance_incentive_data.BYYYY > 2008)
                           GROUP BY dbo.agent_insurance_incentive_data.USERID, dbo.agent_insurance_incentive_data.BMM, dbo.agent_insurance_incentive_data.BYYYY, 
                                                  dbo.agent_insurance_incentive_data.DMM, dbo.agent_insurance_incentive_data.DYYYY, dbo.incentive_agents.department) 
                          AS derived
    WHERE     (userid IN
                              (SELECT     agent
                                FROM          dbo.incentive_agents AS incentive_agents_1)) OR
                          (userid = 'chrisn')
    GROUP BY BMM, BYYYY, userid
    ORDER BY userid, BYYYY, BMM

从概念上讲，这应该相当简单。只需对您的查询采用以下公式。

Declare @Tmp Table(
    Percentage float 
)

Insert Into @Tmp Values (.65)
Insert Into @Tmp Values (.7)
Insert Into @Tmp Values (.75)
Insert Into @Tmp Values (.8)
Insert Into @Tmp Values (.85)
Insert Into @Tmp Values (.9)
Insert Into @Tmp Values (.95)

SELECT 
    CASE
        WHEN Percentage >= .65 AND Percentage < .7 THEN 50
        WHEN Percentage >= .7 AND Percentage < .75 THEN 75
        WHEN Percentage >= .75 AND Percentage < .8 THEN 200
        WHEN Percentage >= .8 AND Percentage < .85 THEN 500
        WHEN Percentage >= .85 AND Percentage < .9 THEN 625
        WHEN Percentage >= .9 AND Percentage < .95 THEN 750
        WHEN Percentage >= .95 AND Percentage < 1 THEN 1000
    END AS Amount,
    Percentage
FROM 
    @Tmp

修改

因为我不能（没有时间）重新创建你的桌子＆amp;数据。

你不应该做类似的事情：

SELECT CASE WHEN Percentage >= .65 AND Percentage < .7 THEN 50 WHEN Percentage >= .7 AND Percentage < .75 THEN 75 WHEN Percentage >= .75 AND Percentage < .8 THEN 200 WHEN Percentage >= .8 AND Percentage < .85 THEN 500 WHEN Percentage >= .85 AND Percentage < .9 THEN 625 WHEN Percentage >= .9 AND Percentage < .95 THEN 750 WHEN Percentage >= .95 AND Percentage < 1 THEN 1000 END AS Amount, * FROM ( --Insert your query here )Tmp2 --OR IF SQL doesn't like the GroupBy/OrderBy statements in the Sub Select Declare @Tmp3 Table( Countreported float, Countnotreported float, [count] float, BMM float, BYYYY float, userid int, party int, percentage decimal ) INSERT INTO @Tmp3 --Insert your query here SELECT CASE WHEN Percentage >= .65 AND Percentage < .7 THEN 50 WHEN Percentage >= .7 AND Percentage < .75 THEN 75 WHEN Percentage >= .75 AND Percentage < .8 THEN 200 WHEN Percentage >= .8 AND Percentage < .85 THEN 500 WHEN Percentage >= .85 AND Percentage < .9 THEN 625 WHEN Percentage >= .9 AND Percentage < .95 THEN 750 WHEN Percentage >= .95 AND Percentage < 1 THEN 1000 END AS Amount, * FROM @Tmp3
