如何用oracle数据库中的C＃填充数据集

Question

我想填充oracle数据集== NULL;

我使用它与.NET框架2.0用C＃

Answer 1

这里是一个例子System.Data.OracleClient的 http://msdn.microsoft.com/en-us/library/system.data.oracleclient.oracledataadapter%28v=vs.71%29.aspx（本例中为1.1，但是将工作相同的同2.0）

（片断从链路）

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); 

这里是ODP（推荐）例如： 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");
