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  *
* daemon started successfully *

N555J:/ $ su    （$只是普通用户，su命令切换到超级用户#）

N555J:/ # cd data/data

N555J:/data/data # ls

查看Media数据库

N555J:/data/data # cd com.android.providers.media

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

N555J:/data/data/com.android.providers.media/databases # ls
external.db     external.db-wal internal.db-shm
external.db-shm internal.db     internal.db-wal

查看某个数据库所有表

N555J:/data/data/com.android.providers.media/databases # sqlite3 external.db

查询表中的数据

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 =
     sql = CREATE TABLE android_metadata (locale TEXT)

    type = table
    name = thumbnails
tbl_name = thumbnails
rootpage =
     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 =
     sql = CREATE INDEX image_id_index on thumbnails(image_id)

    type = table
    name = artists
tbl_name = artists
rootpage =
     sql = CREATE TABLE artists (artist_id INTEGER PRIMARY KEY,artist_key TEXT NOT NULL UNIQUE,artist TEXT NOT NULL)
