　　今天没事简单的练习了下存储过程，感觉总是做些前端的事情把数据库的事情都忘得差不多了！

　　今天是个简单的案例！电话号码的归属地查询的一个小的demo!

　　废话不多说现上项目！

————————————————————————————C#代码———————————————————————————————————————————————

private void Button_Click(object sender, RoutedEventArgs e)
{
string num = txtNum.Text.Trim();
if (num.Length < 7)
{
MessageBox.Show("你输入的电话号码位数太少！","系统提示",MessageBoxButton.OK,MessageBoxImage.Information);
txtNum.Focus();
return;
}
else 
{
string nums = num.Substring(0, 1);

if (nums == "1")
{
List<PhoneMsg> list = new List<PhoneMsg>();

num = num.Substring(0, 7);
SqlParameter[] parms = new SqlParameter[2];
parms[0] = new SqlParameter("@NumPiece", num);
parms[1] = new SqlParameter("@Count",SqlDbType.Int);
parms[1].Direction = ParameterDirection.Output;

DataTable table = SqlHelper.ExecuteQuery("Get_tbPhone_pro",parms);

PhoneMsg pm = new PhoneMsg();
pm.Id = Convert.ToInt32(table.Rows[0]["Id"]);
pm.NumPiece = table.Rows[0]["NumPiece"].ToString();
pm.NumAddress = table.Rows[0]["NumAddress"].ToString();
pm.NumClass = table.Rows[0]["NumClass"].ToString();
pm.NumCode = table.Rows[0]["NumCode"].ToString();

list.Add(pm);
dgMsg.DataContext = list;
MessageBox.Show("查询完成！");
MessageBox.Show("条目数：" + parms[1].Value.ToString());
}
else 
{
MessageBox.Show("电话号码必须得以数字-： 1 开头！", "系统提示", MessageBoxButton.OK, MessageBoxImage.Error);
txtNum.Focus();
return;
}
}


}

——————————————————————————————————存储过程代码————————---————————————————————————————

create procedure Get_tbPhone_pro
(
@NumPiece NVARCHAR(20),
@Count int output
)
as
begin
select @Count= COUNT(*) from tb_Phone
select * from tb_Phone where NumPiece = @NumPiece 
end

drop procedure Get_tbPhone_pro

declare @cc int
execute Get_tbPhone_pro @NumPiece='1352636',@Count=@cc output
select	@cc

———————————————————————————————————————————————————————————————————————————————重点是输出参数是怎么带入和输出的！之前以为是这样

int count = 0;
if (nums == "1")
{
List<PhoneMsg> list = new List<PhoneMsg>();

num = num.Substring(0, 7);
SqlParameter[] parms = new SqlParameter[2];
parms[0] = new SqlParameter("@NumPiece", num);
parms[1] = new SqlParameter("@Count",count);

parms[1].Direction = ParameterDirection.Output;

DataTable table = SqlHelper.ExecuteQuery("Get_tbPhone_pro",parms);

然后把count打印出来就是输出参数，但是尝试多次无效，就是不明白什么道理，后台原来是要这样子！

parms[1] = new SqlParameter("@Count",SqlDbType.Int);

MessageBox.Show("条目数：" + parms[1].Value.ToString());

本文的数据库用的是sql server自带数据Northwind   
   
1.只返回单一记录集的存储过程  
  
SqlConnection sqlconn = new SqlConnection(conn);  
SqlCommand cmd = new SqlCommand();  
// 设置sql连接  
cmd.Connection = sqlconn;  
// 如果执行语句  
cmd.CommandText = "Categoriestest1";  
// 指定执行语句为存储过程  
cmd.CommandType = CommandType.StoredProcedure;  
  
SqlDataAdapter dp = new SqlDataAdapter(cmd);  
DataSet ds = new DataSet();  
// 填充dataset  
dp.Fill(ds);  
// 以下是显示效果  
GridView1.DataSource = ds;  
GridView1.DataBind();  
  
   
  
存储过程Categoriestest1

SqlCommand cmd = new SqlCommand();  
  
cmd.Connection = sqlconn;  
cmd.CommandText = "Categoriestest2";  
cmd.CommandType = CommandType.StoredProcedure;  
sqlconn.Open();  
// 执行并显示影响行数  
Label1.Text = cmd.ExecuteNonQuery().ToString();  
sqlconn.Close();  
  
  
存储过程Categoriestest2

         // 创建参数  
        IDataParameter[] parameters = {  
                 new SqlParameter("rval", SqlDbType.Int,4)  
             };  
         // 将参数类型设置为 返回值类型  
        parameters[0].Direction = ParameterDirection.ReturnValue;  
         // 添加参数  
        cmd.Parameters.Add(parameters[0]);  
  
         sqlconn.Open();  
         // 执行存储过程并返回影响的行数  
        Label1.Text = cmd.ExecuteNonQuery().ToString();  
         sqlconn.Close();  
         // 显示影响的行数和返回值  
        Label1.Text += "-" + parameters[0].Value.ToString() ;  
  
  
存储过程Categoriestest3  
  
CREATE PROCEDURE Categoriestest3

                 new SqlParameter("@CategoryName", SqlDbType.NVarChar,15) ,  
             };  
         // 设置参数类型  
        parameters[0].Direction = ParameterDirection.Output;  // 设置为输出参数  
        parameters[1].Value = "testCategoryName";  
         // 添加参数  
        cmd.Parameters.Add(parameters[0]);  
         cmd.Parameters.Add(parameters[1]);  
  
         sqlconn.Open();  
         // 执行存储过程并返回影响的行数  
        Label1.Text = cmd.ExecuteNonQuery().ToString();  
         sqlconn.Close();  
         // 显示影响的行数和输出参数

 values (@CategoryName,'test1',null)  
set  @id = @@IDENTITY  
 GO  
  
   
  
5. 同时具有返回值、输入参数、输出参数的存储过程  
  
 SqlConnection sqlconn = new SqlConnection(conn);  
         SqlCommand cmd = new SqlCommand();  
         cmd.Connection = sqlconn;

         cmd.CommandType = CommandType.StoredProcedure;  
         // 创建参数  
        IDataParameter[] parameters = {  
                 new SqlParameter("@Id", SqlDbType.Int,4) ,  
                 new SqlParameter("@CategoryName", SqlDbType.NVarChar,15) ,

        parameters[2].Direction = ParameterDirection.ReturnValue;  // 设置为返回值  
        // 添加参数  
        cmd.Parameters.Add(parameters[0]);  
         cmd.Parameters.Add(parameters[1]);  
         cmd.Parameters.Add(parameters[2]);  
  
         sqlconn.Open();  
         // 执行存储过程并返回影响的行数  
        Label1.Text = cmd.ExecuteNonQuery().ToString();  
         sqlconn.Close();  
         // 显示影响的行数，输出参数和返回值  
        Label1.Text += "-" + parameters[0].Value.ToString() + "-" + parameters[2].Value.ToString();  
  
 存储过程Categoriestest5  
  
CREATE PROCEDURE Categoriestest5

set  @id = @@IDENTITY  
return @@rowcount  
 GO  
  
   
 6. 同时返回参数和记录集的存储过程  
    SqlConnection sqlconn = new SqlConnection(conn);  
    SqlCommand cmd = new SqlCommand();  
    cmd.Connection = sqlconn;  
    cmd.CommandText = "Categoriestest6";  
    cmd.CommandType = CommandType.StoredProcedure;

                 new SqlParameter("@CategoryName", SqlDbType.NVarChar,15) ,  
                 new SqlParameter("rval", SqlDbType.Int,4)                   // 返回值  
            };
