CREATE PROC usp_getPage

@PageCount INT=5
AS
SELECT * FROM (SELECT ROW_NUMBER() OVER(ORDER BY classid) AS id,* FROM dbo.Class) AS temp WHERE id BETWEEN
@PageCount*(@PageIndex-1)+1 AND @PageCount*@PageIndex
SET @totalCount=CEILING((SELECT COUNT(*) FROM dbo.Class)*1.0/@PageCount)

PRINT @count
主要是 ROW_NUMBER() OVER()函数可以从1开始给select到的数据集标号
然后,ceiling()函数可以获取与相应值相近的最大整数,如:ceiling(2.1)=3
