OracleClientFactory Class

An OracleClientFactory object allows applications to instantiate ODP.NET classes in a generic way.

Supported Only in ADO.NET 2.0-Compliant ODP.NET

Class Inheritance

System.Object

  System.Data.Common.DbProviderFactory

    Oracle.DataAccess.Client.OracleClientFactory

Declaration

// C#
public sealed class OracleClientFactory : DbProviderFactory

Thread Safety

All public static methods are thread-safe, although instance methods do not guarantee thread safety.

Example

// C#
 
using System;
using System.Data;
using System.Data.Common;
using Oracle.DataAccess.Client;
 
class FactorySample
{
  static void Main()
  {
    string constr = "user id=scott;password=tiger;data source=oracle";
 
    DbProviderFactory factory =
            DbProviderFactories.GetFactory("Oracle.DataAccess.Client");
 
    DbConnection conn = factory.CreateConnection();
 
    try
    {
      conn.ConnectionString = constr;
      conn.Open();
 
      DbCommand cmd = factory.CreateCommand();
      cmd.Connection = conn;
      cmd.CommandText = "select * from emp";
 
      DbDataReader reader = cmd.ExecuteReader();
      while (reader.Read())
        Console.WriteLine(reader["EMPNO"] + " : " + reader["ENAME"]);
    }
    catch (Exception ex)
    {
      Console.WriteLine(ex.Message);
      Console.WriteLine(ex.StackTrace);
    }
  }
}
