本文的數據庫用的是sql server自帶數據Northwind

連接字符串：

string conn = ConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ConnectionString;

confige文件：

<connectionStrings>

<add name="NorthwindConnectionString" connectionString="Data Source=.;Initial Catalog=Northwind;Integrated Security=True"

</connectionStrings>

1. 只返回單一記錄集的存儲過程

SqlConnection sqlconn = new SqlConnection(conn);

SqlCommand cmd = new SqlCommand();

// 設置sql連接

cmd.Connection = sqlconn;

// 如果執行語句

cmd.CommandText = "Categoriestest1";

// 指定執行語句為存儲過程

cmd.CommandType = CommandType.StoredProcedure;

SqlDataAdapter dp = new SqlDataAdapter(cmd);

DataSet ds = new DataSet();

// 填充dataset

dp.Fill(ds);

// 以下是顯示效果

GridView1.DataSource = ds;

GridView1.DataBind();

存儲過程Categoriestest1

CREATE PROCEDURE Categoriestest1

AS

select *

from Categories

GO

2. 沒有輸入輸出的存儲過程

SqlConnection sqlconn = new SqlConnection(conn);

SqlCommand cmd = new SqlCommand();

cmd.Connection = sqlconn;

cmd.CommandText = "Categoriestest2";

cmd.CommandType = CommandType.StoredProcedure;

sqlconn.Open();

// 執行并顯示影響行數

Label1.Text = cmd.ExecuteNonQuery().ToString();

sqlconn.Close();

存儲過程Categoriestest2

CREATE PROCEDURE Categoriestest2 AS

insert into dbo.Categories

(CategoryName,[Description],[Picture])

values ('test1','test1',null)

GO

3. 有返回值的存儲過程

SqlConnection sqlconn = new SqlConnection(conn);

SqlCommand cmd = new SqlCommand();

cmd.Connection = sqlconn;

cmd.CommandText = "Categoriestest3";

cmd.CommandType = CommandType.StoredProcedure;

// 創建參數

IDataParameter[] parameters = {

new SqlParameter("rval", SqlDbType.Int,4)

};

// 將參數類型設置為 返回值類型

parameters[0].Direction = ParameterDirection.ReturnValue;

// 添加參數

cmd.Parameters.Add(parameters[0]);

sqlconn.Open();

// 執行存儲過程并返回影響的行數

Label1.Text = cmd.ExecuteNonQuery().ToString();

sqlconn.Close();

// 顯示影響的行數和返回值

Label1.Text += "-" + parameters[0].Value.ToString() ;

存儲過程Categoriestest3

CREATE PROCEDURE Categoriestest3

AS

insert into dbo.Categories

(CategoryName,[Description],[Picture])

values ('test1','test1',null)

return @@rowcount

GO

4. 有輸入參數和輸出參數的存儲過程

SqlConnection sqlconn = new SqlConnection(conn);

SqlCommand cmd = new SqlCommand();

cmd.Connection = sqlconn;

cmd.CommandText = "Categoriestest4";

cmd.CommandType = CommandType.StoredProcedure;

// 創建參數

IDataParameter[] parameters = {

new SqlParameter("@Id", SqlDbType.Int,4) ,

new SqlParameter("@CategoryName", SqlDbType.NVarChar,15) ,

};

// 設置參數類型

parameters[0].Direction = ParameterDirection.Output; // 設置為輸出參數

parameters[1].Value = "testCategoryName";

// 添加參數

cmd.Parameters.Add(parameters[0]);

cmd.Parameters.Add(parameters[1]);

sqlconn.Open();

// 執行存儲過程并返回影響的行數

Label1.Text = cmd.ExecuteNonQuery().ToString();

sqlconn.Close();

// 顯示影響的行數和輸出參數

Label1.Text += "-" + parameters[0].Value.ToString() ;

存儲過程Categoriestest4

CREATE PROCEDURE Categoriestest4

@id int output,

@CategoryName nvarchar(15)

AS

insert into dbo.Categories

(CategoryName,[Description],[Picture])

values (@CategoryName,'test1',null)

set @id = @@IDENTITY

GO

5. 同時具有返回值、輸入參數、輸出參數的存儲過程

SqlConnection sqlconn = new SqlConnection(conn);

SqlCommand cmd = new SqlCommand();

cmd.Connection = sqlconn;

cmd.CommandText = "Categoriestest5";

cmd.CommandType = CommandType.StoredProcedure;

// 創建參數

IDataParameter[] parameters = {

new SqlParameter("@Id", SqlDbType.Int,4) ,

new SqlParameter("@CategoryName", SqlDbType.NVarChar,15) ,

new SqlParameter("rval", SqlDbType.Int,4)

};

// 設置參數類型

parameters[0].Direction = ParameterDirection.Output; // 設置為輸出參數

parameters[1].Value = "testCategoryName"; // 給輸入參數賦值

parameters[2].Direction = ParameterDirection.ReturnValue; // 設置為返回值

// 添加參數

cmd.Parameters.Add(parameters[0]);

cmd.Parameters.Add(parameters[1]);

cmd.Parameters.Add(parameters[2]);

sqlconn.Open();

// 執行存儲過程并返回影響的行數

Label1.Text = cmd.ExecuteNonQuery().ToString();

sqlconn.Close();

// 顯示影響的行數，輸出參數和返回值

Label1.Text += "-" + parameters[0].Value.ToString() + "-" + parameters[2].Value.ToString();

存儲過程Categoriestest5

CREATE PROCEDURE Categoriestest5

@id int output,

@CategoryName nvarchar(15)

AS

insert into dbo.Categories

(CategoryName,[Description],[Picture])

values (@CategoryName,'test1',null)

set @id = @@IDENTITY

return @@rowcount

GO

6. 同時返回參數和記錄集的存儲過程

SqlConnection sqlconn = new SqlConnection(conn);

SqlCommand cmd = new SqlCommand();

cmd.Connection = sqlconn;

cmd.CommandText = "Categoriestest6";

cmd.CommandType = CommandType.StoredProcedure;

// 創建參數

IDataParameter[] parameters = {

new SqlParameter("@Id", SqlDbType.Int,4) ,

new SqlParameter("@CategoryName", SqlDbType.NVarChar,15) ,

new SqlParameter("rval", SqlDbType.Int,4) // 返回值

};

// 設置參數類型

parameters[0].Direction = ParameterDirection.Output; // 設置為輸出參數

parameters[1].Value = "testCategoryName"; // 給輸入參數賦值

parameters[2].Direction = ParameterDirection.ReturnValue; // 設置為返回值

// 添加參數

cmd.Parameters.Add(parameters[0]);

cmd.Parameters.Add(parameters[1]);

cmd.Parameters.Add(parameters[2]);

SqlDataAdapter dp = new SqlDataAdapter(cmd);

DataSet ds = new DataSet();

// 填充dataset

dp.Fill(ds);

// 顯示結果集

GridView1.DataSource = ds.Tables[0];

GridView1.DataBind();

Label1.Text = "";

// 顯示輸出參數和返回值

Label1.Text += parameters[0].Value.ToString() + "-" + parameters[2].Value.ToString();
