概述
一般来说SDE的试用许可我会建议用户在没有到期之前进行续期，也就是更新许可。否则的话，如果SDE试用许可到期了，除了PostgresSQL数据库之外，我们只能通过SQL语句的方式来进行更新。在到期之前我们可以通过【更新企业级地理数据库许可】工具进行操作：
过期了，只能通过SQL进行许可的更新操作。这是由于SDE的许可信息是存储在SDE空间库里的server_config(根据数据库的不同表名可能有所不同，如SQLSerer的表名为sde_server_config)表中一行中，可以通过
select * from server_config
来查看SDE许可的信息。
在更新许可之前，需要先从ArcGIS Server的许可文件(*.ecp)中找到以arcsdeserver打头的一行，并将其拷贝下来，格式类似：
