双 WHILE 循环？

Question

大局是我需要提取一堆不同的人数据并按站点聚合。最终结果如下所示：

Site1
   Person1 general info
   Person1 sales info
   Person1 customer info
   Person1 vendor info
   Person2 general info
   Person2 sales info
   Person2 customer info
   Person2 vendor info
   Person3 general info
   .
   .
   .
Site2
   Person1 general info
   Person1 sales info
   Person1 customer info
   Person1 vendor info
   Person2 general info
   Person2 sales info
   Person2 customer info
   Person2 vendor info
   Person3 general info
   .
   .
   .
Site 4
   Person1 general info
  ...etc

每个站点可能有也可能没有相同的人。这些站点都在一个 table 中。 Person 信息的 4 个类别中的每一个都在单独的 table 中。所有人的一般信息在 table 1 中，包括站点编号。所有人的销售信息都在 table2 中，还包括每个人的站点编号。客户和供应商信息都在不同的 table 中，但仅引用员工的 personID（而非站点）。

此外，为了通过 bcp 输出我的结果，我从该查询中获取结果并将其放入临时文件 table，然后将每个结果附加到最终文本文件中。

我这里的代码使结果看起来像这样：

Site1
Person1 general info
Person1 sales info
Person1 customer info
Person1 vendor info
Site4
Person2 general info
Person2 sales info
Person2 customer info
Person2 vendor info
Site2
Person3 general info
...etc

这里是一个站点的代码，一个人：

DECLARE @salespersonid INT
DECLARE @siteNum VARCHAR(14)
DECLARE @count INT
DECLARE @rID INT
DECLARE @SQLCmd as VARCHAR(500)
DECLARE @fileName VARCHAR(50)

set @count = (select count(*) from tmp_salesSDrec)
set @rID = 1 --because siteid is sequential and unique in tmp_salesSDrec

WHILE @count > 0
BEGIN

set @siteNum = (select siteNumber from tmp_salesSDrec where rID = @rID)

set @salespersonid = (select salespersonid from tmp_sales01rec where rID = @rID)

--drop the tmp_salestemp table
IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[tmp_salestemp]') AND TYPE IN (N'U'))
DROP TABLE [dbo].[tmp_salestemp]

SELECT field1 into tmp_salestemp
FROM
(
     --SDrec
          SELECT CONCAT(recordID,',',CAST(LayoutVersion as VARCHAR(3)),',',submissionType,',',salesYear,',',siteType,',',',',',',',',',',','
                              ,CAST(siteCode as VARCHAR(6)),',',',',

                         extractDate,',',eor)
          as field1, 1 as sortOrder, recordID
          from tmp_salesSDrec
          where siteNumber = @siteNum
  UNION ALL
     --01rec
          SELECT CONCAT(recordID,',',',',CAST(siteATPCode as VARCHAR(6)),',',empNumber,',',stateNumber,',',',',',',',',firstName,',',',',lastName

                         partnerYouth,',',siteConsent,',',eor)
          as field1, 2 as sortOrder, recordID
          from tmp_sales01rec
          where salespersonid = @salespersonid and siteNumber = @siteNum
  UNION ALL
     --02rec
          select CONCAT(recordID,',',salesgrade,',',siteAttended,',',siteATPCode,',',',',salesYear,',',',',term,',',blockSales,',',workInProgress,',',
                         CAST(sectorID as VARCHAR(25)),',',sectorName,',',',',',',',',PrepInd,',',salesAtmpt,',',salesEarned,',',sectorsalesgrade,',',LOWER(area),',',eor)
          as field1, 3 as sortOrder, recordID
          from tmp_sales02rec
          where salespersonid = @salespersonid and siteNumber = @siteNum
    UNION ALL
     --03rec
          select CONCAT(recordID,',',custType,',',custDate,',',subcustName,',',custScore,',',eor)
          as field1, 4 as sortOrder, recordID
          from tmp_sales03rec
          where salespersonid = @salespersonid
    UNION ALL
     --04rec
          select CONCAT(recordID,',',vendorType,',',otherVendorType,',',vendorDate,',',vendorStatus,',',eor)
          as field1, 5 as sortOrder, recordID
          from tmp_sales04rec
          where salespersonid = @salespersonid
) sq
order by sortOrder, recordID;

SELECT @SQLCmd = 'bcp "select * from [sales].dbo.tmp_salestemp" queryout "c:\bcpTemp.csv" -w -t -T -S && type c:\bcpTemp.csv >> c:\sales_2015.csv' ;
EXEC master..xp_cmdshell @SQLCmd;

     set @rID = @rID + 1;

     set @count = @count - 1;



END

我在想我需要为每个 salespersonID 添加第二个 while 循环，然后为站点添加原始循环。

有没有人有任何建议或更好的方法来完成这个？

Answer 1

您应该能够在没有任何 while 循环的情况下编写此代码。使用基于纯集合的查询会快得多。将您的查询更改为如下所示，然后将其全部导出。

SELECT field1 into tmp_salestemp
FROM
(
     --SDrec
          SELECT CONCAT(recordID,',',CAST(LayoutVersion as VARCHAR(3)),',',submissionType,',',salesYear,',',siteType,',',',',',',',',',',','
                              ,CAST(siteCode as VARCHAR(6)),',',',',
                         TPSCode,',',physicalsiteName,',',siteAddr,',',siteCity,',',sicustate,',',siteZip,',',',',',',adminContFirstName,',',adminContLastName,',',
                         adminContPhone,',',adminContEmail,',',techContFirstName,',',techContLastName,',',techContPhone,',',techContEmail,',',CAST(numreports as VARCHAR(4))
                         ,',',CAST(ConversionFactor as VARCHAR(6)),',',',',calTypeCY,',',',',',',calTypeCY1,',',',',',',calTypeCY2,',',',',',',calTypeCY3,',',',',',',',',',',',',','
                              ,CAST(MatchingName as VARCHAR(2)),',',',',
                         extractDate,',',eor)
          as field1, 1 as sortOrder, recordID, tmp_salesSDrec.siteNumber, convert(int,null) salespersonid
          from tmp_salesSDrec
  UNION ALL
     --01rec
          SELECT CONCAT(recordID,',',',',CAST(siteATPCode as VARCHAR(6)),',',empNumber,',',stateNumber,',',',',',',',',firstName,',',',',lastName
                         ,',',address_1,',',',',city,',',[state],',',zip,',',',',CONVERT(VARCHAR(8),dob,112),',',gender,',',salesgrade,',',',',',',salesgraddate,',',',',',',salesrank,',',',',',',',',',',
                         partnerYouth,',',siteConsent,',',eor)
          as field1, 2 as sortOrder, recordID, tmp_salesSDrec.siteNumber, salespersonid
          from tmp_sales01rec 
          join tmp_salesSDrec 
          on tmp_sales01rec.siteNumber = tmp_salesSDrec.siteNumber
  UNION ALL
     --02rec
          select CONCAT(recordID,',',salesgrade,',',siteAttended,',',siteATPCode,',',',',salesYear,',',',',term,',',blockSales,',',workInProgress,',',
                         CAST(sectorID as VARCHAR(25)),',',sectorName,',',',',',',',',PrepInd,',',salesAtmpt,',',salesEarned,',',sectorsalesgrade,',',LOWER(area),',',eor)
          as field1, 3 as sortOrder, recordID, tmp_salesSDrec.siteNumber, salespersonid
          from tmp_sales01rec 
          join tmp_salesSDrec 
          on tmp_sales01rec.siteNumber = tmp_salesSDrec.siteNumber
    UNION ALL
     --03rec
          select CONCAT(recordID,',',custType,',',custDate,',',subcustName,',',custScore,',',eor)
          as field1, 4 as sortOrder, recordID, tmp_salesSDrec.siteNumber, salespersonid
          from tmp_sales01rec 
          join tmp_salesSDrec 
          on tmp_sales01rec.siteNumber = tmp_salesSDrec.siteNumber
    UNION ALL
     --04rec
          select CONCAT(recordID,',',vendorType,',',otherVendorType,',',vendorDate,',',vendorStatus,',',eor)
          as field1, 5 as sortOrder, recordID, tmp_salesSDrec.siteNumber, salespersonid
          from tmp_sales01rec 
          join tmp_salesSDrec 
          on tmp_sales01rec.siteNumber = tmp_salesSDrec.siteNumber
) sq
order by tmp_salesSDrec.siteNumber, salespersonid, sortOrder, recordID;

我没有你的任何数据，所以我无法测试它，所以它可能需要一些调整。

双 WHILE 循环？
