sqlserver 存儲(chǔ)過程分頁(按多條件排序)

sqlserver 存儲(chǔ)過程分頁，并支持條件排序，需要的朋友可以參考下。

cs頁面調(diào)用代碼：
代碼如下:
　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);
}
}

//調(diào)用存儲(chǔ)過程的函數(shù)

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頁面代碼：

{
%>

}
%>

存儲(chǔ)過程代碼：
代碼如下:
CREATE proc [dbo].[getRecordByPage]
@TotalPage int output,–總頁數(shù)
@RowsCount int output,–總條數(shù)
@PageSize int,–每頁多少數(shù)據(jù)
@CurrentPage int,–當(dāng)前頁數(shù)
@SelectFields nvarchar(1000),–select 語句但是不包含select
@IdField nvarchar(50),–主鍵列
@OrderField nvarchar(50),–排序字段,如果是多個(gè)字段，除最后一個(gè)字段外，后面都要加排序條件（asc/desc），不包含order by,最后一個(gè)排序字段不用加排序條件
@OrderType nvarchar(4),–1升序，0降序
@TableName nvarchar(200),–表名
@strWhere nvarchar(300)–條件
