Question

如何使以下语句将第100行提取到第200行：

SELECT Offices.OfficeID, ContractsBooksCommodities.CommodityID
  FROM ((((Offices 
    INNER JOIN tbl_Sales ON Offices.CompanyID = tbl_Sales.CompanyID) 
    INNER JOIN ContractBooks ON tbl_Sales.CompanyID = ContractBooks.CompanyID)      
    INNER JOIN ContractsBooksAds ON ContractBooks.ContractNum = ContractsBooksAds.ContractNum) 
    INNER JOIN ContractsBooksBrands ON ContractsBooksAds.ContractNum = ContractsBooksBrands.ContractNum) 
    INNER JOIN ContractsBooksCommodities ON ContractsBooksBrands.ContractNum = ContractsBooksCommodities.ContractNum;

Answer 1

这可能很慢：

SELECT Top 101 Offices.OfficeID, ContractsBooksCommodities.CommodityID
  FROM ((((Offices 
    INNER JOIN tbl_Sales ON Offices.CompanyID = tbl_Sales.CompanyID) 
    INNER JOIN ContractBooks ON tbl_Sales.CompanyID = ContractBooks.CompanyID)      
    INNER JOIN ContractsBooksAds ON ContractBooks.ContractNum = ContractsBooksAds.ContractNum) 
    INNER JOIN ContractsBooksBrands ON ContractsBooksAds.ContractNum = ContractsBooksBrands.ContractNum) 
    INNER JOIN ContractsBooksCommodities ON ContractsBooksBrands.ContractNum = ContractsBooksCommodities.ContractNum
WHERE Offices.OfficeID NOT IN (SELECT Top 99 Offices.OfficeID
  FROM ((((Offices 
    INNER JOIN tbl_Sales ON Offices.CompanyID = tbl_Sales.CompanyID) 
    INNER JOIN ContractBooks ON tbl_Sales.CompanyID = ContractBooks.CompanyID)      
    INNER JOIN ContractsBooksAds ON ContractBooks.ContractNum = ContractsBooksAds.ContractNum) 
    INNER JOIN ContractsBooksBrands ON ContractsBooksAds.ContractNum = ContractsBooksBrands.ContractNum) 
    INNER JOIN ContractsBooksCommodities ON ContractsBooksBrands.ContractNum = ContractsBooksCommodities.ContractNum
ORDER BY Offices.OfficeID, ContractsBooksCommodities.CommodityID) 
ORDER BY Offices.OfficeID, ContractsBooksCommodities.CommodityID

我不知道哪些字段使您的排序唯一，但这就是您所需要的，因为MS Access将返回匹配。
