数据透视表中的子查询

Question

我正在使用动态数据透视查询来生成报告：

DECLARE @Columns VARCHAR(MAX)
DECLARE @Columns2 VARCHAR(MAX) 

SET @Columns = ''
SET @Columns2 = ''

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, -5 ,DATEADD(m, DATEDIFF(m, 0,GETDATE()), 0)) 
    AND dates <= DATEADD(m, DATEDIFF(m, 0,GETDATE()), 0)

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

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, -5 ,DATEADD(m, DATEDIFF(m, 0,GETDATE()), 0)) 
    AND dates <= DATEADD(m, DATEDIFF(m, 0,GETDATE()), 0)

SET @Columns2 = LEFT(@Columns2, LEN(@Columns2) - 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  vendor_code,' + @Columns2 + 'FROM BaseData
                PIVOT
                (
                    sum([No. of Case])
                    FOR CLOSED_DATE IN (' +  @Columns + ')
                ) AS PivotTable'

--Print @SQL
EXECUTE sp_executesql @SQL 

现在我想在我的报告中添加供应商名称和供应商代码。供应商名称来自不同的表格

 SELECT VendorName 
 FROM VENDOR_REQUIREMENT  
 WHERE vendorcode = 'ACEA'

请告诉我我必须在哪里使用我的选择来获取供应商名称！

请查找示例数据

提前致谢

Answer 1

只需加入 BaseData cte 中的 vendor_requirement 表，然后在需要的地方选择供应商名称。您还需要按执行 count() 的新字段进行分组

SET @SQL = 'WITH BaseData AS
                (
                   select 
                        t.vendor_code,
                        vr.vendorname,
                        RTRIM(LTRIM(cast(datename(month, [CLOSED_DATE]) as char(15))))+'','' + RTRIM(LTRIM(cast(year([CLOSED_DATE]) as char(20)))) as [CLOSED_DATE],
                        count(t.vendor_code) as [No. of Case] 
                   from #teamp t WITH (NOLOCK)
                   join (select distinct vendorcode, vendorname from  vendor_requirement) vr on t.vendor_code = vr.vendorcode
                   where 
                       [CLOSED_DATE] is not null
                   group by 
                       t.vendor_code, vr.vendorname, CLOSED_DATE
                )   
                SELECT  vendor_code,vendorname,' + @Columns2 + 'FROM BaseData
                PIVOT
                (
                    sum([No. of Case])
                    FOR CLOSED_DATE IN (' + @Columns + ')
                ) AS PivotTable'
                --Print @SQL
EXECUTE sp_executesql @SQL

不确定#team 表的来源。加入该表应该可以。

来自#teamp t WITH (NOLOCK) INNER JOIN VENDOR_REQUIREMENT V ON T.vendor_code=V.vendor_code
