SqlTransaction

大家好，又见面了，我是你们的朋友全栈君。

public void RunSqlTransaction(string myConnString) { SqlConnection myConnection = new SqlConnection(myConnString); myConnection.Open();

SqlCommand myCommand = myConnection.CreateCommand(); SqlTransaction myTrans;

// Start a local transaction myTrans = myConnection.BeginTransaction(); // Must assign both transaction object and connection // to Command object for a pending local transaction myCommand.Connection = myConnection; myCommand.Transaction = myTrans;

try { myCommand.CommandText = “Insert into Region (RegionID, RegionDescription) VALUES (100, ‘Description’)”; myCommand.ExecuteNonQuery(); myCommand.CommandText = “Insert into Region (RegionID, RegionDescription) VALUES (101, ‘Description’)”; myCommand.ExecuteNonQuery(); myTrans.Commit(); Console.WriteLine(“Both records are written to database.”); } catch(Exception e) { try { myTrans.Rollback(); } catch (SqlException ex) { if (myTrans.Connection != null) { Console.WriteLine(“An exception of type ” + ex.GetType() + ” was encountered while attempting to roll back the transaction.”); } } Console.WriteLine(“An exception of type ” + e.GetType() + ” was encountered while inserting the data.”); Console.WriteLine(“Neither record was written to database.”); } finally { myConnection.Close(); } }
