同时向几个表插入数据，SQL语句是
INSERT INTO aaa...
INSERT INTO bbb...
...
try
{
//接受影响行数
com.ExecuteNonQuery();
//提交事务
tran.Commit();
}
catch (Exception ex)
{
//出现异常 即回滚事务 防止出现脏数据
tran.Rollback();
Response.Write(ex.Message);
break;
}
如果第一句，INSERT INTO aaa...成功了，第二句INSERT INTO bbb...出现异常，tran.Rollback();能让第一句insert 插入的数据也消失吗？

- C# code
public void ExecuteTransaction(string connectionString){ using (OleDbConnection connection = new OleDbConnection(connectionString)) { OleDbCommand command = new OleDbCommand(); OleDbTransaction transaction = null; // Set the Connection to the new OleDbConnection. command.Connection = connection; // Open the connection and execute the transaction. try { connection.Open(); // Start a local transaction transaction = connection.BeginTransaction(); // Assign transaction object for a pending local transaction. command.Connection = connection; command.Transaction = transaction; // Execute the commands. command.CommandText = "Insert into Region (RegionID, RegionDescription) VALUES (100, 'Description')"; command.ExecuteNonQuery(); command.CommandText = "Insert into Region (RegionID, RegionDescription) VALUES (101, 'Description')"; command.ExecuteNonQuery(); // Commit the transaction. transaction.Commit(); Console.WriteLine("Both records are written to database."); } catch (Exception ex) { Console.WriteLine(ex.Message); try { // Attempt to roll back the transaction. transaction.Rollback(); } catch { // Do nothing here; transaction is not active. } } // The connection is automatically closed when the // code exits the using block. }}

也可以使用存储过程.
------解决方案--------------------------------------------------------
可以的，只要在同一个事务下任何操作失败都会使所有操作回滚
------解决方案--------------------------------------------------------

当然可以，都写在一个事务里
- C# code
SqlTransaction trans = new SqlTransaction();SqlCommand cmd = new SqlCommand("insert into aaa...", conn); cmd.Transaction = trans;

可以的

不能回滚它叫事务干嘛
你可以了解一些内部机制就知道它是怎么具体实现了
------解决方案--------------------------------------------------------
嗯，写在同一个事务里， 如果有一条失败，就全部回滚了， 这个用存储过程来操作比较好些
