调用存储过程

1、通过表格查找数据
SqlConnection con = new SqlConnection(sqlCon);
con.Open();
string strID = "select ID from Vehicle where cph='" + cph + "'";
SqlCommand com = new SqlCommand(strID, con);
SqlDataReader dr = com.ExecuteReader();
while (dr.Read())
{
　　vehID = dr["id"].ToString();
}
con.Close();

2、通过调用存储过程查找string格式的数据

方法一：

int IsAdmin = 0;
SqlConnection Conn = new SqlConnection(sqlCon);
Conn.Open();
SqlCommand comm = new SqlCommand("SelectCustomByUser", Conn);
comm.CommandType = CommandType.StoredProcedure;
comm.Parameters.Add("@UserId", SqlDbType.VarChar, 20);
comm.Parameters["@UserId"].Value = UserID;
//com.Parameters.Add("@IsAdmin", SqlDbType.VarChar, 20);//参数可多个
//com.Parameters["@IsAdmin"].Value = IsAdmin;
SqlDataReader dr = comm.ExecuteReader();
if (dr.HasRows)
{
　　while (dr.Read())
　　{
　　　　IsAdmin = int.Parse(dr["id"].ToString());
　　}
}
Conn.Close();

方法二：

string connString = "server=.;uid=User;pwd=******;database=Gis_Server";
SqlConnection sqlconn = new SqlConnection(connString);
SqlCommand cmd = new SqlCommand();
cmd.Connection = sqlconn;
cmd.CommandText = "SelectLastRecByVehID";
cmd.CommandType = CommandType.StoredProcedure;
var sqlParmas = new SqlParameter[]{ new SqlParameter("@VehID",vehID) };
cmd.Parameters.Add(sqlParmas[0]);
sqlconn.Open();
SqlDataReader dr =cmd.ExecuteReader();
string strLastVol = "0" ;
if (dr.HasRows)
{
　　while (dr.Read())
　　{
　　　　strLastVol = dr["VolValue"].ToString();
　　　　break ;
　　}
}
int nCurVol = Convert.ToInt32(strLastVol)

3、通过调用存储过程查出DataSet格式的数据

SqlConnection Conn = new SqlConnection(sqlCon);
Conn.Open();
SqlCommand comm = new SqlCommand("SelectCustomByUser", Conn);
comm.CommandType = CommandType.StoredProcedure;
comm.Parameters.Add("@UserID", SqlDbType.VarChar, 20);
comm.Parameters["@UserID"].Value = UserID;
DataSet ds = new DataSet();
try
{
　　SqlDataAdapter ada = new SqlDataAdapter(comm);
　　ada.Fill(ds);
　　Conn.Close();
　　return ds;
}
catch (Exception ex)
{
　　Console.WriteLine(ex.Message);
}

4、通过存储过程添加数据

string strConn = "Data Source=.;Initial Catalog=Gis_Server;User ID=sa;Password=******";
SqlConnection con = new SqlConnection(strConn);
con.Open();
SqlCommand cmd = new SqlCommand("SaveRFIDData", con);cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@DevIDe", SqlDbType.VarChar, 20);
cmd.Parameters["@DevIDe"].Value = temp.DevId;
cmd.Parameters.Add("@RFID", SqlDbType.VarChar, 20);
cmd.Parameters["@RFID"].Value = temp.RFID;
try
{
　　cmd.ExecuteNonQuery();
　　con.Close();
}
catch (Exception ex)
{
　　MessageBox.Show(ex.Message);
}
