本程序是在vagrant的升级程序上增加了SQL数据库的更新升级功能系统中采用了ACCES来存储数据更新的指令

从而达到逐步执行SQL代码的功能，因为在SQL中要创建表、存储过程、视图等对象时，需要删除原有老的对象，但是SQ

-This procedure is in the vagrant escalation procedures increased by SQL database upgrade function to update the system used to store data ACCES updated instructions to achieve the progressive implementation of the functions of SQL code, because in SQL to create tables, stored procedures, views, etc. object, need to delete the original object of the old, but SQL does not support these directives will be stored together resulting error is therefore ACCES to store data
