本文实例讲述了C#处理Access中事务的方法。分享给大家供大家参考。具体如下:
Access不能像SQL server一样直接执行多条语句,但是把多条语句绑成事务还是可以一起执行的. 所谓事务,就是把多件事情当做一件事情来处理。也就是大家同在一条船上! 由一个事务来完成多个表的同步操作,要么都执行成功,要么都不成功.下面举个例子,用C#实现Access数据库事务的处理方法: 向一个表提交数据,同时更新另一个表中的数据

注:Access的事务不支持自动锁定(经试验已经证实),因此Access最好用于本机的程序,b/s中做好不要用,除非你不用事务处理~~!
希望本文所述对大家的C#程序设计有所帮助。
