Question

我试图从表中找出不到10％的收入帐户。下面是表快照。基本上，我想在表格中添加Revenue mix列。

ACCOUTS REVENUE REVENUEMIX
ACCOUNT1    100     2%
ACCOUNT2    200     4%
ACCOUNT3    500     9%
ACCOUNT4    1000    19%
ACCOUNT5    1500    28%
ACCOUNT6    2000    38%
TOTAL 5300  100%

Answer 1

DECLARE @P INT;
SET @P = 10;

WITH CTE AS
(
    SELECT  ACCOUNTS,
            REVENUE,
            CAST(REVENUE AS DECIMAL(5,0))/(SUM(REVENUE) OVER())*100 REVENUEMIX
    FROM dbo.YourTable
)
SELECT *
FROM CTE
WHERE REVENUEMIX < @P;

Here is a sqlfiddle及其演示。我得到的样本数据的结果是：

╔══════════╦═════════╦═════════════╗
║ ACCOUNTS ║ REVENUE ║ REVENUEMIX  ║
╠══════════╬═════════╬═════════════╣
║ ACCOUNT1 ║     100 ║ 1.886792452 ║
║ ACCOUNT2 ║     200 ║ 3.773584905 ║
║ ACCOUNT3 ║     500 ║ 9.433962264 ║
╚══════════╩═════════╩═════════════╝

Answer 2

尝试REPLACE() and CAST()

FIDDLE DEMO

SELECT *
FROM tab_1 where cast(Replace(REVENUEMIX,'%','') as decimal(10,4))<10

如果我正确地阅读了问题，您是否希望将示例表中显示的RevenueMix列包含在仅包含Account and Revenue的表中？这样的事情应该有效：

create table #table (
    account nvarchar(10),
    revenue int
    )

insert #table values
('ACCOUNT1',    100    ),
('ACCOUNT2',    200    ),
('ACCOUNT3',    500    ),
('ACCOUNT4',    1000   ),
('ACCOUNT5',    1500   ),
('ACCOUNT6',    2000    )

declare @TotalRevenue int
declare @MinimumRevenueMix numeric(8,2) = 10.0
select @TotalRevenue = SUM(Revenue) from #table

select  a.account,
        a.revenue,
        convert(nvarchar(20), a.RevenueMix) + '%' RevenueMix
    from (
        select  account,
                revenue,
                convert(numeric(8,2), convert(float, revenue) / convert(float, @TotalRevenue)) * 100 RevenueMix
            from #table
        ) a
    where
        a.RevenueMix < @MinimumRevenueMix

drop table #table
