下面的示例创建一个 OracleConnection 和一个 OracleTransaction 。它还演示了如何使用 ** BeginTransaction ** 、 Commit 和 Rollback 方法。
**public void RunOracleTransaction(string myConnString)
{
OracleConnection myConnection = new OracleConnection(myConnString);
myConnection.Open(); **
**OracleCommand myCommand = myConnection.CreateCommand();
OracleTransaction myTrans; **
**// Start a local transaction
myTrans = myConnection.BeginTransaction(IsolationLevel.ReadCommitted);
// Assign transaction object for a pending local transaction
myCommand.Transaction = myTrans; **
**try
{
myCommand.CommandText = "INSERT INTO Dept (DeptNo, Dname, Loc) values (50, 'TECHNOLOGY', 'DENVER')";
myCommand.ExecuteNonQuery();
myCommand.CommandType ** **= CommandType.StoredProcedure；
myCommand.CommandText="prc_test"; ** **
myCommand.ExecuteNonQuery();
myTrans.Commit();
Console.WriteLine("Both records are written to database.");
}
catch(Exception e)
{
myTrans.Rollback();
Console.WriteLine(e.ToString());
Console.WriteLine("Neither record was written to database.");
}
finally
{
myConnection.Close();
}
}
