高手发表下, 在C#怎么调用上面的存储过程;或者有更好的方法 Thanks
------解决方案--------------------
- C# code
CREATE PROC P_TEST@Name VARCHAR(20),@Rowcount INT OUTPUTASBEGIN SELECT * FROM T_Customer WHERE [email protected] SET @Rowcount=@@ROWCOUNTENDGO------------------------------------------------------存储过程调用如下:----------------------------------------------------DECLARE @i INTEXEC P_TEST 'A',@i OUTPUTSELECT @i--结果/*Name Address Tel ---------- ---------- -------------------- A Address Telphone （所影响的行数为 1 行） ----------- 1（所影响的行数为 1 行）*/------------------------------------------------------DotNet 部分(C#)--WebConfig 文件:----------------------------------------------------...... </system.web> <!-- 数据库连接字符串 --> <appSettings> <add key="ConnectString" value="server=(local);User ID=sa;Password=;database=Test" /></appSettings> </configuration>------------------------------------------------------C#代码:(用到两个测试控件,DataGrid1(用于显示绑定结果集合),Lable(用于显示存储过程返回单值)----------------------------------------------------//添加数据库引用using System.Data.SqlClient;...... private void Page_Load(object sender, System.EventArgs e) { // 在此处放置用户代码以初始化页面 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; //添加输入查询参数、赋予值 myCommand.Parameters.Add("@Name",SqlDbType.VarChar); myCommand.Parameters["@Name"].Value ="A"; //添加输出参数 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(); //得到存储过程输出参数 Label1.Text=myCommand.Parameters["@Rowcount"].Value.ToString(); if (myConnection.State == ConnectionState.Open) { myConnection.Close(); } }----------------------------------------------------运行以上代码即可(返回记录集合和存储过程返回值)
