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" providerName="System.Data.SqlClient"/>
</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();
// 執行並顯示影響行數
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();
// 執行存儲過程並返回影響的行數
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();
// 執行存儲過程並返回影響的行數
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();
// 執行存儲過程並返回影響的行數
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();
存儲過程Categoriestest6
