sqlserver 存储过程分页，并支持条件排序，需要的朋友可以参考下。
cs页面调用代码：代码如下:
public int TotalPage = 0;
public int PageCurrent = 1;
public int PageSize = 25;
public int RowsCount = 0;
string userid, username;
public DataTable dt = new DataTable();
public string path, userwelcome;
public string opt,cid;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
if (Request.Params["page"] == null || Request.Params["page"].ToString().Equals(""))
PageCurrent = 1;
else
PageCurrent=int.Parse(Request.Params["page"].ToString());
this.getPage(out TotalPage, out RowsCount, PageSize, PageCurrent);
}
}
//调用存储过程的函数
private void getPage(out int totalPage, out int rowsCount, int pageSize, int currentPage)
{
SqlParameter[] parameters = {
new SqlParameter("@TotalPage", SqlDbType.Int,4),
new SqlParameter("@RowsCount", SqlDbType.Int,4),
new SqlParameter("@PageSize", SqlDbType.Int,4),
new SqlParameter("@CurrentPage", SqlDbType.Int,4),
new SqlParameter("@SelectFields", SqlDbType.NVarChar,700),
new SqlParameter("@IdField",SqlDbType.NVarChar,50),
new SqlParameter("@OrderField", SqlDbType.NVarChar,200),
new SqlParameter("@OrderType", SqlDbType.NVarChar,2),
new SqlParameter("@TableName", SqlDbType.NVarChar,300),
new SqlParameter("@strWhere", SqlDbType.NVarChar,300),
};
parameters[0].Direction = ParameterDirection.Output;
parameters[1].Direction = ParameterDirection.Output;
parameters[2].Value = pageSize;
parameters[3].Value = currentPage;
parameters[4].Value = "a.RLId,a.companyName,a.webSite,a.isRL,a.ordernum,a.isrl,a.userid";
parameters[5].Value = "a.RLId";
parameters[6].Value = " a.isrl asc , a.orderNum ";
parameters[7].Value = "1";
parameters[8].Value = "qiYeRenling a";
parameters[9].Value = "1=1";//
DataSet ds = Wm23Abc.DBUtility.DbHelperSQL.RunProcedure("getRecordByPage", parameters, "dt");
dt = ds.Tables[0];
totalPage = int.Parse(parameters[0].Value.ToString());
rowsCount = int.Parse(parameters[1].Value.ToString());
}
.aspx页面代码：
| 公司名称 | 公司网址 | 认领状态 |
| <%= dt.Rows[i]["companyName"].ToString() %>排序值：<%= dt.Rows[i]["ordernum"].ToString() %> | <%= dt.Rows[i]["webSite"].ToString() %> 是否认领：<%=dt.Rows [i]["userid"].ToString () %> | <%= dt.Rows[i]["isRL"].ToString().Equals("0") ? "认领该企业" : "该企业已被认领"%> |
第 <%=PageCurrent %> 页 共 <%=RowsCount %> 条 共 <%=TotalPage%> 页
<% if (PageCurrent != 1)
{
%>
首 页
上一页
<%
}
if (PageCurrent != TotalPage)
{
%>
下一页
末 页
<%
}
%>
存储过程代码：
代码如下:
CREATE proc [dbo].[getRecordByPage]
@TotalPage int output,--总页数
@RowsCount int output,--总条数
@PageSize int,--每页多少数据
@CurrentPage int,--当前页数
@SelectFields nvarchar(1000),--select 语句但是不包含select
@IdField nvarchar(50),--主键列
@OrderField nvarchar(50),--排序字段,如果是多个字段，除最后一个字段外，后面都要加排序条件（asc/desc），不包含order by,最后一个排序字段不用加排序条件
@OrderType nvarchar(4),--1升序，0降序
@TableName nvarchar(200),--表名
@strWhere nvarchar(300)--条件
As
Begin
declare @RecordCount float
declare @PageNum int --分页依据数
Declare @Compare nvarchar(50)--比较字段区分min或者max
Declare @Compare1 nvarchar(2) --大于号“>” 或者小于号"<“
Declare @OrderSql nvarchar(10)--排序字段
declare @Sql nvarchar(4000)
Declare @TemSql nvarchar(1000)
Declare @nRd int
declare @afterRows int
declare @tempTableName nvarchar(10)
if(@OrderType='1')
Begin
set @OrderSql=' asc'
End
Else
Begin
set @OrderSql= ' desc'
End
if(isnull(@strWhere, '')<>'')

--print(@Sql)
exec sp_executeSql @Sql
End
else if(@CurrentPage=@TotalPage)
begin
set @afterRows=@RowsCount-(@CurrentPage-1)*@PageSize
set RowCount @afterRows
if(@OrderType='1')
begin
set @OrderField=REPLACE(@OrderField,'asc','lai512343975')//这里用变量将asc和desc互换，哈哈，太神了
set @OrderField=REPLACE(@OrderField,'desc','asc')
set @OrderField=REPLACE(@OrderField,'lai512343975','desc')
set @Sql='select ' @SelectFields ' from ' @TableName ' where ' @strWhere ' order by ' @OrderField ' desc' ',' @IdField ' asc'
end
else
begin

set @OrderField=REPLACE(@OrderField,'asc','desc')
set @OrderField=REPLACE(@OrderField,'lai512343975','asc')
set @Sql='select ' @SelectFields ' from ' @TableName ' where ' @strWhere ' order by ' @OrderField ' asc ' ',' @IdField ' asc'
print(@Sql)
end
--print(@Sql)
exec sp_executeSql @Sql
end
else
Begin
set @nRd=@PageSize* (@CurrentPage-1)
print(@nRd)
set RowCount @PageSize
set @Sql='select ' @SelectFields ' from ' @TableName ' where ' @strWhere ' and ' @IdField ' not in (select top ' cast(@nRd as nvarchar(10)) ' ' @IdField ' from ' @TableName ' where ' @strWhere ' order by ' @OrderField ' ' @OrderSql ',' @IdField ' asc) ' ' order by ' @OrderField ' ' @OrderSql ',' @IdField ' asc'
exec sp_executeSql @Sql
--Print(@sql)
End
end
