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(); }}
