Android使用命令行操作数据库 _数据库

仰天大笑出门去，我辈岂是蓬蒿人。这篇文章主要讲述Android使用命令行操作数据库相关的知识，希望能为你提供帮助。
【Android使用命令行操作数据库】所有的应用程序本地文件都存放在/data/data/目录下

C:\Users\nicole> adb shell * daemon not running. starting it now on port 5039 * * daemon started successfully *N555J:/ $ su（$只是普通用户，su命令切换到超级用户#）N555J:/ # cd data/dataN555J:/data/data # ls

查看Media数据库

N555J:/data/data # cd com.android.providers.mediaN555J:/data/data/com.android.providers.media # ls cache code_cache databases files shared_prefs

查看数据库所有表的建表语句(每个SQLite数据库中都还有一个隐藏的sqlite_master表)

sqlite> select * from sqlite_master; type = table name = android_metadata tbl_name = android_metadata rootpage = 3 sql = CREATE TABLE android_metadata (locale TEXT)type = table name = thumbnails tbl_name = thumbnails rootpage = 6 sql = CREATE TABLE thumbnails (_id INTEGER PRIMARY KEY,_data TEXT,image_id INTEGER,kind INTEGER,width INTEGER,height INTEGER)type = index name = image_id_index tbl_name = thumbnails rootpage = 7 sql = CREATE INDEX image_id_index on thumbnails(image_id)type = table name = artists tbl_name = artists rootpage = 10 sql = CREATE TABLE artists (artist_id INTEGER PRIMARY KEY,artist_key TEXT NOT NULL UNIQUE,artist TEXT NOT NULL)
