SQL Server 2000 通用单表或视图查询存储过程及C#调用示例

create proc Common
@pagesize int, --页大小
@pageindex int,--第几页
@Tbname varchar(50),--表名
@TFields varchar(500),--要查询的字段
@order varchar(20),--显示顺序
@id varchar(20), --列标识名一般为ID号
@whereCondition varchar(500), --执行查询的条件不带 where 关键字,
@total int output,
@PageCount int output
as
begin
declare @sqlstr nvarchar(2000)
declare @MaxOrMin char(3)
declare @OpChar char(2)

if len(@order)=3
begin
set @MaxOrMin = 'max'
set @OpChar = '>='
end
if len(@order)=4
begin
set @MaxOrMin = 'min'
set @OpChar = '<='
end

set @sqlstr='select @a = count('+@id+') from '+@Tbname+' where '+@whereCondition
exec sp_executesql @sqlstr,N'@a int output',@total output

if @total % @pagesize = 0
begin
set @PageCount = @total / @pagesize
end
else
begin
set @PageCount = (@total / @pagesize)+1
end
set @sqlstr='select top '+cast(@pagesize as nvarchar)+' '+@TFields+
' from '+@Tbname+'
where '+@id+' '+@OpChar+'
(
select '+@MaxOrMin+' ('+@id+')
from
(
select top '+cast(((@pageindex-1)*@pagesize+1) as nvarchar)+' '+@id+' from '+@Tbname+' where '+@whereCondition+' order by '+@id+' '+@order+'
)as tblTmp
) and '+@whereCondition+' order by '+@id+' '+@order
exec sp_executesql @sqlstr
end

将下面的方法写到C#数据库操作类中将返回一个dataset，将上面的存储过程建在SQLserver2000数据库中,以下示例是asp.net中的调用

//分回一个数据集并利用分页 同时可以得到记录总数及页总数用于列表页显示 一个连接一个command对象,另外还有sqldataadapter,dataset
public static DataSet getCurrentDataSet(string ggSelectColumns, string ggtableName, string ggwhere, int ggcurpage, int ggpagesize, string ggxuName, string ggorder, out int ggpagecount, out int ggRecordCount)
{//可以作为一个类方法取得当前数据集

//接收传入参数列表
int pagesize = ggpagesize; //接收页大小
int curpage = ggcurpage; //当前第几页

string where = ggwhere; //查询的where条件
string xuName = ggxuName; //排序字段一般为数据表中记录编号
string orderName = ggorder; //用来排序的列名 一般为表记录编号,或时间
string SelectColumns = ggSelectColumns; //要选择的列
string tableName = ggtableName; //要查询的表名

//内部使用变量
//int pagecount; //符合条件分页数
//int dblRecordCount; //符合条件记录数

//Response.Write("<br>" + sqlstr + "<br>");

// 打开数据库取得数据到当前记录集
