SQL Server 2008 分页复杂查询

Question

我在对以下查询进行分页时遇到问题。我已经尝试了示例here，但它给出了一些“光标”错误。

SELECT Countries.CountryID, Countries.Name as CountryName, Customers.FName, Customers.LName, Customers.EMail, LTRIM(Organizations.OrgName) AS OrgName, Organizations.URL, Addresses.City, Addresses.State, Countries.Name,Addresses.Zip 
FROM (((Customers INNER JOIN CustomerMembershipXRef ON Customers.CustomerID = CustomerMembershipXRef.CustomerID) INNER JOIN Organizations ON Customers.OrgID = Organizations.OrgID) INNER JOIN (Countries INNER JOIN Addresses ON Countries.CountryID = Addresses.CountryID) ON Customers.CustomerID = Addresses.EntityID) INNER JOIN Memberships ON (Organizations.OrgID = Memberships.OrgID) AND (CustomerMembershipXRef.MembershipID = Memberships.MembershipID)
WHERE (Memberships.ExpireDate > GETDATE()) AND (Addresses.EntityTypeID=200) AND (Customers.RecordStatus='A') AND (Memberships.RecordStatus='A') AND(Organizations.OrgTypeID=46 OR Organizations.OrgTypeID=55) AND (Addresses.State = 'MI ')
ORDER BY Customers.LName ASC, Organizations.OrgName, Addresses.City, Addresses.State

我需要让它每页显示 50...这个查询。

SELECT CountryID, CountryName, FName, LName, EMail, OrgName, OrgURL, City, State, CountryName,Zip
FROM (SELECT Countries.CountryID as CountryID, Countries.Name as CountryName, Customers.FName as FName, Customers.LName as LName, Customers.EMail as EMail, LTRIM(Organizations.OrgName) AS OrgName, Organizations.URL as OrgURL, Addresses.City as City, Addresses.State as State, Countries.Name as CountryName, Addresses.Zip as Zip, ROW_NUMBER() OVER (ORDER BY Customers.LName ASC, Organizations.OrgName, Addresses.City, Addresses.State) AS RowNum
FROM (((Customers INNER JOIN CustomerMembershipXRef ON Customers.CustomerID = CustomerMembershipXRef.CustomerID) INNER JOIN Organizations ON Customers.OrgID = Organizations.OrgID) INNER JOIN (Countries INNER JOIN Addresses ON Countries.CountryID = Addresses.CountryID) ON Customers.CustomerID = Addresses.EntityID) INNER JOIN Memberships ON (Organizations.OrgID = Memberships.OrgID) AND (CustomerMembershipXRef.MembershipID = Memberships.MembershipID)))
AS PaginatedTable
WHERE (PaginatedTable.RowNum BETWEEN 15 AND 33) AND ((Memberships.ExpireDate > GETDATE()) AND (Addresses.EntityTypeID=200) AND (Customers.RecordStatus='A') AND (Memberships.RecordStatus='A') AND(Organizations.OrgTypeID=46 OR Organizations.OrgTypeID=55) AND (Addresses.State = 'MI '))

错误是“直接执行 SQL；没有游标。”

Answer 1

我发现括号和列定义的放置以及 orderby 存在一些问题......这是工作查询

SELECT CountryID,ExpireDate,EntityTypeID,MRecordStatus,CRecordStatus,OrgTypeID,CountryName,FName,LName,EMail,OrgName,OrgURL,City,State,CountryName,Zip
FROM (
    SELECT Countries.CountryID as CountryID, Countries.Name as CountryName, Customers.FName as FName, Customers.LName as LName, Customers.EMail as EMail, LTRIM(Organizations.OrgName) AS OrgName, Organizations.URL as OrgURL, Addresses.City as City, Memberships.ExpireDate as ExpireDate, Addresses.EntityTypeID as EntityTypeID, Memberships.RecordStatus as MRecordStatus, Organizations.OrgTypeID as OrgTypeID, Customers.RecordStatus as CRecordStatus, Addresses.State as State, Addresses.Zip as Zip, ROW_NUMBER() OVER (ORDER BY LName ASC) AS RowNum
    FROM((((Customers INNER JOIN CustomerMembershipXRef ON Customers.CustomerID = CustomerMembershipXRef.CustomerID) INNER JOIN Organizations ON Customers.OrgID = Organizations.OrgID) INNER JOIN (Countries INNER JOIN Addresses ON Countries.CountryID = Addresses.CountryID) ON Customers.CustomerID = Addresses.EntityID) INNER JOIN Memberships ON (Organizations.OrgID = Memberships.OrgID) AND (CustomerMembershipXRef.MembershipID = Memberships.MembershipID))
    WHERE ExpireDate > GETDATE() AND EntityTypeID=200 AND Customers.RecordStatus='A' AND Memberships.RecordStatus='A' AND (OrgTypeID=46 OR OrgTypeID=55) AND State = 'MI  '
)
AS PaginatedTable
WHERE PaginatedTable.RowNum BETWEEN 150 AND 200

Answer 2

在 SQL 2012 及更高版本中，有很好的 OFFSET 和 FETCH 子句作为 ORDER BY 子句的一部分。

http://technet.microsoft.com/en-us/library/gg699618(v=sql.110).aspx

但是，由于您使用的是 SQL 2008，因此一种解决方案是使用 ROW_NUMBER()。

下面，我正在从冒险作品数据库中的产品表中分页记录。

这可以转化为存储过程并由前端应用程序调用。

TSQL：

-- PAGE CNT & ITEM CNT
DECLARE @PAGECNT INT = 5;
DECLARE @ITEMCNT INT = 50;

-- USE COMMON TABLE EXPRESSION
;WITH CTE_PRODUCT AS
(
SELECT 
    ROW_NUMBER() OVER (ORDER BY NAME) as RID,
    *
FROM 
    [AdventureWorks2012].[Production].[Product] P
)
SELECT * 
FROM CTE_PRODUCT
WHERE RID >= @PAGECNT * @ITEMCNT AND RID < (@PAGECNT+1) * @ITEMCNT;

输出：

嗨，b747fp，

你测试你的答案了吗？？

我使用公用表表达式 (CTE) 的原因是由于处理 QUERY 的逻辑方式，别名不可用于 WHERE 子句。

见下文，您的解决方案不起作用！
