sqlserver 存储过程分页代码并说明了用vc#调用上面的存储过程

代码如下:


declare @TotalCount int 
declare @TotalPageCount int 
exec P_viewPage_A 'type1','*','id','','id asc',1,0,4,3,@TotalCount output,@TotalPageCount output 

select * from type1 


Create PROC P_viewPage_A

如何用vc#调用上面的存储过程 

 

复制代码代码如下:


private void fyDB() 

DataTable dt = new DataTable(); 
string con = System.Configuration.ConfigurationSettings.AppSettings["connectionstring"]; 
SqlConnection conn = new SqlConnection(con); 
SqlCommand comm = new SqlCommand("P_viewPage_A", conn); //建立SqlCommand对象

comm.Parameters.Add("@TotalPageCount", SqlDbType.Int); 
comm.Parameters["@TotalCount"].Direction = ParameterDirection.Output; //设置参数的输出类型 
comm.Parameters["@TotalPageCount"].Direction = ParameterDirection.Output; //设置参数的输出类型 
comm.Parameters["@TableName"].Value = "type1";//表名

int id1; 
if (Request.QueryString["id"] == null) 
id1 = 1; 
else 
id1 = Convert.ToInt32(Request.QueryString["id"]); 
comm.Parameters["@PageIndex"].Value = id1;//当前页数 
conn.Open(); 
// SqlDataReader asr = comm.ExecuteReader(); 
//int dtr = (int)comm.ExecuteScalar(); 
SqlDataReader sdr = comm.ExecuteReader(); 
int i=0; 
//while (sdr.Read()) 
//{ 
// dt.Rows[i][0] = sdr.GetValue(0);

GridView1.DataSource = dt; 
GridView1.DataBind(); 
// dt.Rows[0][0]; 
sdr.Close(); 
// Response.Write(dtr); 
Response.Write(comm.Parameters["@TotalCount"].Value + "<br>"); 
Response.Write(comm.Parameters["@TotalPageCount"].Value + "<br>"); 
// if((Int32)comm.Parameters["RETURN_VALUE"].Value==0) 
conn.Close(); 
//string conStr = System.Configuration.ConfigurationSettings.AppSettings["connectionstring"]; 
//SqlConnection connection = new SqlConnection(conStr); 
//DataSet dataSet = new DataSet(); 
//connection.Open(); 
//SqlDataAdapter sqlDA = new SqlDataAdapter(); 
//sqlDA.SelectCommand = BuildQueryCommand(connection, "P_viewPage_A", parameters); 
//sqlDA.Fill(dataSet, tableName); 
//connection.Close(); 
//return dataSet;
