CREATE PROC P_TEST
@Name VARCHAR(20),
@Rowcount INT OUTPUT
AS
BEGIN
SELECT * FROM T_Customer WHERE NAME=@Name
SET @Rowcount=@@ROWCOUNT
END
GO
----------------------------------------------------------------------------------------
--存儲過程調用如下:
----------------------------------------------------------------------------------------
DECLARE @i INT
EXEC P_TEST 'A',@i OUTPUT
SELECT @i
--結果
/*
Name Address Tel
---------- ---------- --------------------
A Address Telphone
（所影響的行數為 1 行）
-----------
1
（所影響的行數為 1 行）
*/

--DotNet 部分(C#)
--WebConfig 文件:
----------------------------------------------------------------------------------------
......
</system.web>
<!-- 數據庫連接字符串
-->
<appSettings>
<add key="ConnectString" value="server=(local);User ID=sa;Password=;database=Test" />
</appSettings>
</configuration>
----------------------------------------------------------------------------------------
--C#代碼:(用到兩個測試控件,DataGrid1(用於顯示綁定結果集合),Lable(用於顯示存儲過程返回單值)
----------------------------------------------------------------------------------------
//添加數據庫引用
using System.Data.SqlClient;
......
private void Page_Load(object sender, System.EventArgs e)
{
// 在此處放置用戶代碼以初始化頁面
String DBConnStr;
DataSet MyDataSet=new DataSet();
System.Data.SqlClient.SqlDataAdapter DataAdapter=new System.Data.SqlClient.SqlDataAdapter();
DBConnStr=System.Configuration.ConfigurationSettings.AppSettings["ConnectString"];
System.Data.SqlClient.SqlConnection myConnection = new System.Data.SqlClient.SqlConnection(DBConnStr);
if (myConnection.State!=ConnectionState.Open)
{
myConnection.Open();
}
System.Data.SqlClient.SqlCommand myCommand = new System.Data.SqlClient.SqlCommand("P_Test",myConnection);
myCommand.CommandType=CommandType.StoredProcedure;
//添加輸入查詢參數、賦予值
myCommand.Parameters.Add("@Name",SqlDbType.VarChar);
myCommand.Parameters["@Name"].Value ="A";
//添加輸出參數
myCommand.Parameters.Add("@Rowcount",SqlDbType.Int);
myCommand.Parameters["@Rowcount"].Direction=ParameterDirection.Output;
myCommand.ExecuteNonQuery();
DataAdapter.SelectCommand = myCommand;
if (MyDataSet!=null)
{
DataAdapter.Fill(MyDataSet,"table");
}
DataGrid1.DataSource=MyDataSet;
DataGrid1.DataBind();
//得到存儲過程輸出參數
Label1.Text=myCommand.Parameters["@Rowcount"].Value.ToString();
if (myConnection.State == ConnectionState.Open)
{
myConnection.Close();
}
}
----------------------------------------------------------------------------------------
運行以上代碼即可(返回記錄集合和存儲過程返回值)
