sql server分页存储过程

利用表变量实现分页

一、

 CREATE PROCEDURE [dbo].[GetRecordFromPage] 
    @SelectList            VARCHAR(2000),    --欲选择字段列表
    @TableSource        VARCHAR(100),    --表名或视图表 
    @SearchCondition    VARCHAR(2000),    --查询条件
    @OrderExpression    VARCHAR(1000),    --排序表达式
    @PageIndex            INT = 1,        --页号,从0开始
    @PageSize            INT = 10        --页尺寸
AS 
BEGIN
    IF @SelectList IS NULL OR LTRIM(RTRIM(@SelectList)) = ''
    BEGIN
        SET @SelectList = '*'
    END
    PRINT @SelectList
    
    SET @SearchCondition = ISNULL(@SearchCondition,'')
    SET @SearchCondition = LTRIM(RTRIM(@SearchCondition))
    IF @SearchCondition <> ''
    BEGIN
        IF UPPER(SUBSTRING(@SearchCondition,1,5)) <> 'WHERE'
        BEGIN
            SET @SearchCondition = 'WHERE ' + @SearchCondition
        END
    END
    PRINT @SearchCondition

    SET @OrderExpression = ISNULL(@OrderExpression,'')
    SET @OrderExpression = LTRIM(RTRIM(@OrderExpression))
    IF @OrderExpression <> ''
    BEGIN
        IF UPPER(SUBSTRING(@OrderExpression,1,5)) <> 'WHERE'
        BEGIN
            SET @OrderExpression = 'ORDER BY ' + @OrderExpression
        END
    END
    PRINT @OrderExpression

    IF @PageIndex IS NULL OR @PageIndex < 1
    BEGIN
        SET @PageIndex = 1
    END
    PRINT @PageIndex
    IF @PageSize IS NULL OR @PageSize < 1
    BEGIN
        SET @PageSize = 10
    END
    PRINT  @PageSize

    DECLARE @SqlQuery VARCHAR(4000)

    SET @SqlQuery='SELECT '+@SelectList+',RowNumber 
    FROM 
        (SELECT ' + @SelectList + ',ROW_NUMBER() OVER( '+ @OrderExpression +') AS RowNumber 
          FROM '+@TableSource+' '+ @SearchCondition +') AS RowNumberTableSource 
    WHERE RowNumber BETWEEN ' + CAST(((@PageIndex - 1)* @PageSize+1) AS VARCHAR) 
    + ' AND ' + 
    CAST((@PageIndex * @PageSize) AS VARCHAR) 
    PRINT @SqlQuery
    SET NOCOUNT ON
    EXECUTE(@SqlQuery)
    SET NOCOUNT OFF
 
    RETURN @@RowCount
END

 CREATE PROCEDURE [dbo].[GetRecordFromPage] 
    @SelectList            VARCHAR(2000),    --欲选择字段列表
    @TableSource        VARCHAR(100),    --表名或视图表 
    @SearchCondition    VARCHAR(2000),    --查询条件

    SET @SearchCondition = LTRIM(RTRIM(@SearchCondition))
    IF @SearchCondition <> ''
    BEGIN

        END
    END
    PRINT @OrderExpression

    IF @PageIndex IS NULL OR @PageIndex < 1
    BEGIN
        SET @PageIndex = 1

    PRINT @PageIndex
    IF @PageSize IS NULL OR @PageSize < 1
    BEGIN
        SET @PageSize = 10
    END
    PRINT  @PageSize

    DECLARE @SqlQuery VARCHAR(4000)

    SET @SqlQuery='SELECT '+@SelectList+',RowNumber 
    FROM 
        (SELECT ' + @SelectList + ',ROW_NUMBER() OVER( '+ @OrderExpression +') AS RowNumber

    + ' AND ' + 
    CAST((@PageIndex * @PageSize) AS VARCHAR) 
    PRINT @SqlQuery
    SET NOCOUNT ON
    EXECUTE(@SqlQuery)
    SET NOCOUNT OFF
 
    RETURN @@RowCount
END

 三、

从数据表中取出第n条到第m条的记录的方法

从publish 表中取出第 n 条到第 m 条的记录：

SELECT TOP m-n+1 *

FROM publish

WHERE (id NOT IN

　　　　(SELECT TOP n-1 id

　　　　 FROM publish))

id 为publish 表的关键字

 ------------------------

分页方案：

select top 页大小 *

from table1

where id>

(select max (id) from

(select top ((页码-1)*页大小) id from table1 order by id) as T

)

order by id

全部的sql语句： 

--获取指定页的数据：
CREATE PROCEDURE pagination3
@tblName varchar(255), -- 表名
@strGetFields varchar(1000) = ''*'', -- 需要返回的列 
@fldName varchar(255)='''', -- 排序的字段名
@PageSize int = 10, -- 页尺寸
@PageIndex int = 1, -- 页码
@doCount bit = 0, -- 返回记录总数, 非 0 值则返回
@OrderType bit = 0, -- 设置排序类型, 非 0 值则降序
@strWhere varchar(1500) = '''' -- 查询条件 (注意: 不要加 where)
AS

declare @strSQL varchar(5000) -- 主语句
declare @strTmp varchar(110) -- 临时变量
declare @strOrder varchar(400) -- 排序类型

if @doCount != 0
begin
if @strWhere !=''''
set @strSQL = "select count(*) as Total from [" + @tblName + "] where "+@strWhere
else
set @strSQL = "select count(*) as Total from [" + @tblName + "]"
end
--以上代码的意思是如果@doCount传递过来的不是0，就执行总数统计。以下的所有代码都是@doCount为0的情况：
else
begin
if @OrderType != 0
begin
set @strTmp = "<(select min"
set @strOrder = " order by [" + @fldName +"] desc"
--如果@OrderType不是0，就执行降序，这句很重要！
end
else
begin
set @strTmp = ">(select max"
set @strOrder = " order by [" + @fldName +"] asc"
end

if @PageIndex = 1
begin
if @strWhere != '''' 

set @strSQL = "select top " + str(@PageSize) +" "+@strGetFields+ "
　　　　　　　　from [" + @tblName + "] where " + @strWhere + " " + @strOrder
else

set @strSQL = "select top " + str(@PageSize) +" "+@strGetFields+ " 
　　　　　　　　from ["+ @tblName + "] "+ @strOrder
--如果是第一页就执行以上代码，这样会加快执行速度
end
else
begin
--以下代码赋予了@strSQL以真正执行的SQL代码 
　
set @strSQL = "select top " + str(@PageSize) +" "+@strGetFields+ " from ["
+ @tblName + "] where [" + @fldName + "]" + @strTmp + "(["+ @fldName + "]) 
　　　　　　from (select top " + str((@PageIndex-1)*@PageSize) + " ["+ @fldName + "] 
　　　　　　from [" + @tblName + "]" + @strOrder + ") as tblTmp)"+ @strOrder

if @strWhere != ''''
set @strSQL = "select top " + str(@PageSize) +" "+@strGetFields+ " from ["
+ @tblName + "] where [" + @fldName + "]" + @strTmp + "(["
+ @fldName + "]) from (select top " + str((@PageIndex-1)*@PageSize) + " ["
+ @fldName + "] from [" + @tblName + "] where " + @strWhere + " "
+ @strOrder + ") as tblTmp) and " + @strWhere + " " + @strOrder
end 

end 

exec (@strSQL)
