SQL SERVER 2000中的TOP分页

CREATE PROCEDURE [Zhzuo_GetItemsPage]
    @PageIndex INT, /*@PageIndex从计数,0为第一页*/
    @PageSize INT, /*页面大小*/
    @RecordCount INT OUT, /*总记录数*/
    @PageCount INT OUT /*页数*/

AS

/*获取记录数*/
SELECT @RecordCount = COUNT(*) FROM Production.Product
/*计算页面数据*/
SET @PageCount = CEILING(@RecordCount * 1.0 / @PageSize)
/*TOP记录数*/
DECLARE @TOPCOUNT INT
SET @TOPCOUNT = @RecordCount - @PageSize * @PageIndex

DECLARE @SQLSTR NVARCHAR(1000)

IF @PageIndex = 0 OR @PageCount <= 1
BEGIN
    SET @SQLSTR =N'SELECT TOP '+STR(@PageSize)+
    'ProductID,Name FROM Production.Product ORDER BY ProductID DESC'
END
ELSE
BEGIN
    IF @PageIndex = @PageCount - 1
    BEGIN
       SET @SQLSTR =N'SELECT * FROM ( SELECT TOP ' + STR(@TOPCOUNT) +
       'ProductID,Name FROM Production.Product ORDER BY ProductID ASC) T ORDER BY ProductID DESC'
    END
    ELSE
    BEGIN
       SET @SQLSTR =N' SELECT TOP '+STR(@PageSize)+'* FROM (SELECT TOP ' + STR(@TOPCOUNT) +
       'ProductID,Name FROM Production.Product ORDER BY ProductID ASC) T ORDER BY ProductID DESC'
    END
END

/*执行*/
EXEC (@SQLSTR)

以上存储过程对页数进行判断，如果是第一页或最后一页，进行特殊处理。其他情况使用2次TOP翻转。其中排序条件为ProductID倒序。最后通过EXECUTE执行SQL字符串拼串。
