我有一些表有一些记录现在想用一些逻辑重复这个表内容。我有两个日期开始日期和终止日期,意味着记录从start_date开始到结束终止日期,它会正常工作,但问题是计算金额, 逻辑是金额计算公式
basesalary / 12 * ( SUTARate / 100 ) * ( x.num+1)
如果这个数量少于SUTAMaximumAmount
这个数量被使用,否则为0.还有一件事,如果金额将保留,年份完成,然后从明年重新开始计算.. x.num是临时表保持90到1的数字
表
BaseSalary| S_Date | T_Date | SUTARate| SUTAMaximumAmount |A_S_Percent
48000 | 7-1-2013 | 3-15-2015 | 1.1 | 300 | 5
我的结果是

我想要这样的结果

查询
SELECT dateadd(M, (x.num),d.StartDate) AS TheDate,
Round( case when ((convert(float,d.SUTARate)/100* convert(integer,d.BaseSalary) / 12)*(x.num+1)) <=CONVERT(money,d.SUTAMaximumAmount)

临时表
create TABLE #Table (
num int NOT NULL,
);
;WITH Nbrs ( n ) AS (
SELECT 0 UNION ALL
SELECT 1 + n FROM Nbrs WHERE n < 99 )
INSERT #Table(num)
SELECT n FROM Nbrs
OPTION ( MAXRECURSION 99 )
此表在上面的查询中用作x
答案 0 :(得分:0)
我创建了this SQLFiddle。
-- Numbers table is probably a good idea
WITH Nbrs ( num ) AS
(
SELECT 0 UNION ALL
SELECT 1 + num FROM Nbrs WHERE num < 99
)
-- All columns, except for 'num' come from myTbl
SELECT dateadd(M, (num),S_Date) AS TheDate,
Round(
CASE
WHEN (SUTARate / 100) * (BaseSalary / 12) <= SUTAMaximumAmount
THEN (SUTARate / 100) * (BaseSalary / 12)
ELSE 0
END
, 2) As Amount
-- This may be the number you were trying to multiply
,DatePart(Month, dateadd(M, (num),S_Date)) As PotentialMultiiplier
FROM Nbrs AS x, myTbl AS d
WHERE (num >= 0)
AND (num <= (DateDiff(M, S_Date, T_Date)) )
我不完全确定你的目标是什么,但你可能在数字表的正确轨道上。因为您要使用的结果不会随着时间的推移而发生太大变化(即,几乎每个月的金额都为44美元),因此很难确定查询的正确代码。因此,我建议您提供一组不同的数据,以便更好地进行结果检查。
如果您在提供的链接中使用SQL,您可以使用更好的代码重新发布,然后我们可以更好地解决您的问题。
