在数据库中开始一个事务。

下面的示例创建一个 OracleConnection 和一个 OracleTransaction。它演示了如何使用 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();
}
}
