This class includes methods like create, insert, delete and update for data CRUD. Public static final String SQL_CREATE_BOOK_ENTRY_TABLE = "CREATE TABLE " + TABLE_NAME + " (" +īookEntry.Let’s start with the implementation:We will be developing an app where a user can store a string, and it will display on the TextView on screen.Let’s first create our main screenĪndroid provides us with the SQLiteOpenHelper class which helps us to interact with the SQLite Database. Public static final String COL_DESCRIPTION = "book_description" Public static final String COL_NO_PAGES = "book_pages" Public static final String COL_BOOKNAME = "book_name" SQL_CREATE_BOOK_ENTRY_TABLE public static final String TABLE_NAME = "books" In version 1 of the application, we defined a variable named TABLE_NAME and.The following example illustrates the second option that was taken.

This looks okay right? This upgrade could leave dangling tables (and might fail if you use “DROP TABLE”) if you change the name of the table in one upgrade to another and you call the same lines of code later on. If you are having pre built data base than copy it in asset folder and create an new class as DataBaseHelper which implements SQLiteOpenHelper Than use following code. You might have the following in your upgrade section of your app: db.execSQL(drop + Books.TABLE_BOOKS) It’s worth noting that this solution will not work well for changing of table names.

When using your own SQLite database in Android, most people take for granted future releases of the application they are working on. Looking at the Android Developer documentation can also lead you down a rickety path. ![]() The post explains quite well the drawbacks of some of the solutions that I also went through, but their final solution can also leave you in trouble. Ill Update My Answer becoz now a days Android Studio update in Android Studio 3.1 or up to other like now 3. You can use a very simple Android Studio's feature Database Inspector.Where you can inspect, query, and modify your app’s databases using the new Database Inspector. See the Notepad sample application in the SDK for an example. The easiest way to see realtime Database are: For Android Studio 4.1 Canary 6 and higher. After reading this blog post (and a few others) on how to use the onUpgrade() method for your Android SQLite Database, I thought I should share my experience about how to correctly upgrade your database. It will also be beneficial to highlight why the final solution listed in that blog post would also fail at some point for some scenarios. Studio preview Jetpack & Compose libraries Wear.
