摘　　要：触发器是数据库应用程序中比较高级的应用,灵活使用触发器可以大大增强应用程序的健壮性和可恢复性。同时触发器还能够使开发人员轻松地实现一些复杂的功能,增加程序开发效率。通过实例介绍了触发器在考勤管理信息系统中灵活实现交叉制表。Trigger is a more advanced application in database-programming, and flexibly using the triggers can greatly strengthen the stalwart and recoverability. At the same time trigger can also help developers achieve some complicated functions easily, and then increase the efficiency of program-developing. This paper introduces that trigger carry out crosstabulation flexibly in the Attendance Management Information System by examples.
