在一般的小数据分页是我们就用简单的分页功能就可以了,但如果上百万级数据分页了,那么我就不得不考虑到高效mssql存储过程分页代码哦。
declare @TotalCount int
declare @TotalPageCount int
exec P_viewPage_A 'type1','*','id','','id asc',1,0,4,3,@TotalCount output,@TotalPageCount output

select * from type1


Create PROC P_viewPage_A

@TableName VARCHAR(200), --表名
@FieldList VARCHAR(2000), --显示列名,如果是全部字段则为*
@PrimaryKey VARCHAR(100), --单一主键或唯一值键
@Where VARCHAR(2000), --查询条件 不含'where'字符,如id>10 and len(userid)>9
@Order VARCHAR(1000), --排序 不含'order by'字符,如id asc,userid desc,必须指定asc或desc
--注意当@SortType=3时生效,记住一定要在最后加上主键,否则会让你比较郁闷
@SortType INT, --排序规则 1:正序asc 2:倒序desc 3:多列排序方法
@RecorderCount INT, --记录总数 0:会返回总记录
@PageSize INT, --每页输出的记录数
@PageIndex INT, --当前页数 111cn.net
@TotalCount INT OUTPUT, --记返回总记录
@TotalPageCount INT OUTPUT --返回总页数
AS
SET NOCOUNT ON
IF ISNULL(@TotalCount,'') = '' SET @TotalCount = 0
SET @Order = RTRIM(LTRIM(@Order))
SET @PrimaryKey = RTRIM(LTRIM(@PrimaryKey))
SET @FieldList = REPLACE(RTRIM(LTRIM(@FieldList)),' ','')
WHILE CHARINDEX(', ',@Order) > 0 OR CHARINDEX(' ,',@Order) > 0
BEGIN
SET @Order = REPLACE(@Order,', ',',')
SET @Order = REPLACE(@Order,' ,',',')
END
IF ISNULL(@TableName,'') = '' OR ISNULL(@FieldList,'') = ''
OR ISNULL(@PrimaryKey,'') = ''
OR @SortType 3
OR @RecorderCount BEGIN
PRINT('ERR_00')
RETURN
