C#中数据库事务、存储过程基本用法

SQL 事务

 public bool UpdateQsRegisterSql(List<string> ids, int newQueueId, string newQueueName)
        {
            using (SqlConnection con = new SqlConnection(DBHelper.Instance.ConStr))
            {
                SqlTransaction tran = null;
                try
                {
                    con.Open();
                    SqlCommand cmd = con.CreateCommand();
                    tran = con.BeginTransaction(IsolationLevel.ReadCommitted);
                    cmd.Transaction = tran;

                    foreach (string item in ids)
                    {
                        cmd.CommandText = @"update qs_register set queueid='" + newQueueId
                            + "',queuename='" + newQueueName + "' where id='" + item + "'";
                        cmd.ExecuteNonQuery();
                    }

                    tran.Commit();
                    return true;
                }
                catch (Exception ex)
                {
                    tran.Rollback();
                    return false;
                }
            }
        }

Oracle事务

  public bool UpdateQsRegisterOrcl(List<string> ids, int newQueueId, string newQueueName)
        {
            using (OleDbConnection con = new OleDbConnection(DBHelper.Instance.ConStr))
            {
                OleDbTransaction tran = null;
                try
                {
                    con.Open();
                    OleDbCommand cmd = con.CreateCommand();
                    tran = con.BeginTransaction(IsolationLevel.ReadCommitted);
                    cmd.Transaction = tran;

                    foreach (string item in ids)
                    {
                        cmd.CommandText = @"update qs_register set queueid='" + newQueueId
                            + "',queuename='" + newQueueName + "' where id='" + item + "'";
                        cmd.ExecuteNonQuery();
                    }

                    tran.Commit();
                    return true;
                }
                catch (Exception ex)
                {
                    tran.Rollback();
                    return false;
                }
            }
        }
