sql server分页存储过程

 

sql server分页存储过程

利用表变量实现分页

一、

CREATEPROCEDURE[dbo].[GetRecordFromPage]
@SelectListVARCHAR(2000), --欲选择字段列表
@TableSourceVARCHAR(100), --表名或视图表 
@SearchConditionVARCHAR(2000), --查询条件
@OrderExpressionVARCHAR(1000), --排序表达式
@PageIndexINT=1, --页号,从0开始
@PageSizeINT=10--页尺寸
AS
BEGINIF
@SelectList ISNULL OR LTRIM(RTRIM(@SelectList)) =''
BEGIN 
SET @SelectList='*'
END 
PRINT@SelectList
SET @SearchCondition = ISNULL (@SearchCondition,'') 
SET @SearchCondition = LTRIM(RTRIM(@SearchCondition)) 
IF@SearchCondition<>''
BEGINIF
UPPER(SUBSTRING(@SearchCondition,1,5)) <> 'WHERE' 
BEGIN
SET @SearchCondition='WHERE '+@SearchCondition
END ENDPRINT@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 ISNULL OR @PageIndex<1
BEGIN
SET @PageIndex=1
END
PRINT @PageIndex
IF @PageSize ISNULL 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) ASVARCHAR)      +' AND '+CAST((@PageIndex*@PageSize) ASVARCHAR)      
PRINT @SqlQuery
SET NOCOUNT ONEXECUTE(@SqlQuery)     SET NOCOUNT OFFRETURN @@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：CREATEPROCEDURE 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(4000) -- 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= "selectcount(*) 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= "<(selectmin" set@strOrder= " orderby[" + @fldName +"]desc" --如果@OrderType不是0，就执行降序，这句很重要！
end 
else
begin
set @strTmp= ">(selectmax" set@strOrder= " orderby[" + @fldName +"]asc" 
end
if @PageIndex=1
begin if @strWhere!='''' 
set @strSQL= "select top " +str(@PageSize) +" "+@strGetFields+ " 　　　　　　　　
from[" + @tblName + "] where " +@strWhere+ " " +@strOrder else
set @strSQL= "selecttop " +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 = "selecttop " +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 (selecttop " +str((@PageIndex-1)*@PageSize) + " [" + @fldName + "] from [" + @tblName + "] where " +@strWhere+ " " +@strOrder+ ") as tblTmp) and " +@strWhere+ " " +@strOrder
end 
end 
exec (@strSQL)
