如何用oracle数据库中的C＃填充数据集

我正在尝试填充oracle数据集== NULL;

我正在使用带有C＃的.net框架2.0

Answer 1

这是一个system.data.oracleclient示例http://msdn.microsoft.com/en-us/library/system.data.oracleclient.oracledataadapter%28v=vs.71%29.aspx （此示例为1.1但将起作用与2.0相同）

OracleConnection conn = new OracleConnection("Data Source=Oracle8i;Integrated Security=yes"); Conn.Open; OracleCommand cmd = conn.CreateCommand(); cmd.CommandText = "sp_pkg.getdata"; cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.Add(new OracleParameter("a1", OracleType.Cursor)).Direction = ParameterDirection.Output; cmd.Parameters.Add(new OracleParameter("a2", OracleType.Cursor)).Direction = ParameterDirection.Output; DataSet ds = new DataSet(); OracleDataAdapter adapter = new OracleDataAdapter(cmd); adapter.Fill(ds); 

这是一个ODP（推荐）示例： http ： //www.oracle.com/technology/sample_code/tech/windows/odpnet/DSPopulate/ViewProducts.cs.html

 //Instantiate OracleDataAdapter to create DataSet productsAdapter = new OracleDataAdapter(); //Fetch Product Details productsAdapter.SelectCommand = new OracleCommand("SELECT " + "Product_ID , " + "Product_Name , " + "Product_Desc , " + "Category, " + "Price " + "FROM Products",conn); //Instantiate DataSet object productsDataSet = new DataSet("productsDataSet"); //Fill the DataSet with data from 'Products' database table productsAdapter.Fill(productsDataSet, "Products"); //setting 'productsDataSet' as the datasouce and 'Products' table //as the table to which the 'productsDataGrid' is Bound. productsDataGrid.SetDataBinding(productsDataSet,"Products");
