今天遇到要分页处理批量数据，要自己编写存储过程，在网上看上如下作者写得很好，故借鉴，结合自身要求并改之，
引用地址：http://51cndo.blog.51cto.com/491222/102320
内容如下：
参数：分页大小，第几页，需要得到的字段 ，需要查询的表 ， 查询条件，排序的字段名，排序的类型，主键名称
/*通用分页存储过程*/
USE HotelManagementSystem
GO
IF EXISTS(SELECT * FROM sys.objects WHERE NAME='cndoup_GetPageOfRecords')
DROP PROCEDURE cndoup_GetPageOfRecords
GO
--创建存储过程
CREATE PROCEDURE cndoup_GetPageOfRecords
@pageSize int = 20, --分页大小
@currentPage int , --第几页
@columns varchar(1000) = '*', --需要得到的字段
@tableName varchar(100), --需要查询的表
@condition varchar(1000) = '', --查询条件, 不用加where关键字
@ascColumn varchar(100) = '', --排序的字段名 (即 order by column asc/desc)
@bitOrderType bit = 0, --排序的类型 (0为升序,1为降序)
@pkColumn varchar(50) = '' --主键名称
AS
BEGIN --存储过程开始
DECLARE @strTemp varchar(300)
DECLARE @strSql varchar(5000) --该存储过程最后执行的语句
DECLARE @strOrderType varchar(1000) --排序类型语句 (order by column asc或者order by column desc)
BEGIN
IF @bitOrderType = 1 --降序
BEGIN
SET @strOrderType = ' ORDER BY '+@ascColumn+' DESC'
SET @strTemp = '<(SELECT min'
END
ELSE --升序
BEGIN
SET @strOrderType = ' ORDER BY '+@ascColumn+' ASC'
SET @strTemp = '>(SELECT max'
END
IF @currentPage = 1 --第一页
BEGIN
IF @condition != ''
SET @strSql = 'SELECT TOP '+STR(@pageSize)+' '+@columns+' FROM '+@tableName+
' WHERE '+@condition+@strOrderType
ELSE
SET @strSql = 'SELECT TOP '+STR(@pageSize)+' '+@columns+' FROM '+@tableName+@strOrderType
END
ELSE -- 其他页
BEGIN
IF @condition !=''
SET @strSql = 'SELECT TOP '+STR(@pageSize)+' '+@columns+' FROM '+@tableName+
' WHERE '+@condition+' AND '+@pkColumn+@strTemp+'('+@pkColumn+')'+' FROM (SELECT TOP '+STR((@currentPage-1)*@pageSize)+
' '+@pkColumn+' FROM '+@tableName'where'+@condition+@strOrderType+') AS TabTemp)'+@strOrderType
ELSE
SET @strSql = 'SELECT TOP '+STR(@pageSize)+' '+@columns+' FROM '+@tableName+
' WHERE '+@pkColumn+@strTemp+'('+@pkColumn+')'+' FROM (SELECT TOP '+STR((@currentPage-1)*@pageSize)+' '+@pkColumn+
' FROM '+@tableName+@strOrderType+') AS TabTemp)'+@strOrderType
END
END
EXEC (@strSql)
END
--存储过程结束
结合自身实际，借鉴上位作者编码的存储过程如下：
******************************************************************
CREATE PROCEDURE [dbo].[UP_GetRecordByPage]
@tblName varchar(255), -- 表名
@fldName varchar(255), -- 主键字段名
@PageSize int = 10, -- 页尺寸
@PageIndex int = 1, -- 页码
@IsReCount 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(1000) = '' -- 查询条件 (注意: 不要加 where)
AS
declare @strSQL varchar(6000) -- 主语句
declare @strTmp varchar(300) -- 临时变量
declare @strOrder varchar(400) -- 排序类型
if @OrderType != 0
begin
set @strTmp = '<(select min'
set @strOrder = ' order by [' + @fldName +'] desc'
end
else
begin
set @strTmp = '>(select max'
set @strOrder = ' order by [' + @fldName +'] asc'
end
set @strSQL = 'select top ' + str(@PageSize) + ' * 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) + ' * from ['
+ @tblName + '] where [' + @fldName + ']' + @strTmp + '(['
+ @fldName + ']) from (select top ' + str((@PageIndex-1)*@PageSize) + ' ['
+ @fldName + '] from [' + @tblName + '] where ' + @strWhere + ' '
+ @strOrder + ') as tblTmp) and ' + @strWhere + ' ' + @strOrder
if @PageIndex = 1
begin
set @strTmp =''
if @strWhere != ''
set @strTmp = ' where ' + @strWhere
set @strSQL = 'select top ' + str(@PageSize) + ' * from ['
+ @tblName + ']' + @strTmp + ' ' + @strOrder
end
if @IsReCount != 0
begin
set @strSQL = 'select count(*) as Total from [' + @tblName + ']'
if @strWhere != ''
set @strSQL = 'select count(*) as Total from [' + @tblName + ']'+' where ' + @strWhere
end
exec (@strSQL)
调用：
public DataSet GetList(int PageSize, int PageIndex, string strWhere)
{
SqlParameter[] parameters = {
new SqlParameter("@tblName", SqlDbType.VarChar, 255),
new SqlParameter("@fldName", SqlDbType.VarChar, 255),
new SqlParameter("@PageSize", SqlDbType.Int),
new SqlParameter("@PageIndex", SqlDbType.Int),
new SqlParameter("@IsReCount", SqlDbType.Bit),
new SqlParameter("@OrderType", SqlDbType.Bit),
new SqlParameter("@strWhere", SqlDbType.VarChar,1000),
};
parameters[0].Value = "Product";
parameters[1].Value = "ProductID";
parameters[2].Value = PageSize;
parameters[3].Value = PageIndex;
parameters[4].Value = 0;
parameters[5].Value = 0;
parameters[6].Value = strWhere;
return DbHelperSQL.RunProcedure("UP_GetRecordByPage", parameters, "ds");
}
