Question

我正在为报告使用动态数据透视表脚本。以下是我的剧本。

> dat2[1,2] <- 2   
> dat2[2,2] <-2; dat2[3,2]<-2; dat2[4,2]<-4
>  mod <-  lm( res ~ A+B, dat2) 
>  summary(mod)

Call:
lm(formula = res ~ A + B, data = dat2)

Residuals:
     Min       1Q   Median       3Q      Max 
-2.42819 -0.59241 -0.04483  0.62482  2.12461

将是我的isnull函数，因此将零替换为null。请指教!!

这是我的新版Print @SQL

   DECLARE @Columns VARCHAR(MAX)
set @Columns= ''

SELECT @Columns = @Columns + (QUOTENAME(RTRIM(LTRIM(cast(datename(month, [dates]) as char(15))))+',' + RTRIM(LTRIM(cast(year([dates]) as char(20))))) + ',') FROM efoxsfc.dbo.FTX_FA_Calender 
WHERE 1=1 
AND CAST(dates AS DATETIME) >= DATEADD(mm, -35 ,DATEADD(m, DATEDIFF(m, 0,GETDATE()), 0)) 
AND dates <= DATEADD(m, DATEDIFF(m, 0,GETDATE()), 0)

SET @Columns = LEFT(@Columns, LEN(@Columns) - 1)

DECLARE @SQL NVARCHAR(MAX) 
set @SQL= ''
SET @SQL =
'WITH BaseData AS
(
     select 
        vendor_code,
        RTRIM(LTRIM(cast(datename(month, [CLOSED_DATE]) as char(15))))+'','' + RTRIM(LTRIM(cast(year([CLOSED_DATE]) as char(20)))) as [CLOSED_DATE],
        count(vendor_code) as [No. of Case] 
   from #teamp t WITH (NOLOCK)
      where 
       [CLOSED_DATE] is not null
  group by 
       vendor_code, CLOSED_DATE
)   
SELECT * 
FROM BaseData
PIVOT
(
    sum([No. of Case])
    FOR CLOSED_DATE IN (' +  @Columns + ')
) AS PivotTable'

您需要声明另一个变量：

DECLARE @Columns2 VARCHAR(MAX) = ''

然后做主要的事情：

SELECT @Columns2 = @Columns2 + 'ISNULL(' + (QUOTENAME(RTRIM(LTRIM(cast(datename(month, [dates]) as char(15))))+',' + RTRIM(LTRIM(cast(year([dates]) as char(20))))) + ', 0) AS ' + (QUOTENAME(RTRIM(LTRIM(cast(datename(month, [dates]) as char(15))))+',' + RTRIM(LTRIM(cast(year([dates]) as char(20))))) + ',') FROM efoxsfc.dbo.FTX_FA_Calender 
WHERE 1=1 
AND CAST(dates AS DATETIME) >= DATEADD(mm, -35 ,DATEADD(m, DATEDIFF(m, 0,GETDATE()), 0)) 
AND dates <= DATEADD(m, DATEDIFF(m, 0,GETDATE()), 0)

SET @Columns2 = LEFT(@Columns2, LEN(@Columns2) - 1)

然后使用它：

...
SELECT ' + @Columns2 + '
FROM BaseData
PIVOT
...

在哪里使用isnull函数
