sqlite> 1.5. 修改数据表global中数据值
## 修改global表中wifi_on的值，where_id表示在数据表中排行第几个，value为修改值
sqlite> update global set value=2 where _id=14;
sqlite> select * from global;
14|wifi_on|2 ## 说明已经修改过来了1.6. 在数据表中插入一个新的数据
## 由上面1.4已知道数据表global中共有47个数据，那接下来新增加的数据说是做为第48个
## 新添加connectivity_change_delay的数据，设定值为0
sqlite> insert into global values(48,'connectivity_change_delay',0);
sqlite> select * from global;
48|connectivity_change_delay'|0
## 以上可以查看到，说明已经添加进来了，接下来重启系统就可以生效了2. Android数据库settings命令设置
可以直接通过settings命令进行操作
