In this video we use the SQLiteDatabase class' execSQL method to create our database tables. Learn how it is used in this video.
- [Instructor] Now that we've prepared a constant string…that holds our create statement,…we can go back over to our…DatabaseSQLiteOpenHelper class.…Let's do that now.…Here, on line 20, we're going to pass a string…into execute sql method.…This is going to correspond to our create statement string.…It was inside of our RecipeContract class…and we called it Create_Recipe_Entry_Table.…
Then we would want to do the same thing…for our recipe step table.…I'm going to grab the recipe step creation statement…from the gist that I've created for this course.…You can also copy it from the exercise files.…And this is going to go inside of our RecipeContract class.…Go back there and let's add it right underneath…the create statement that we created…for the recipe entry table.…
Right here on line 18.…Let's just briefly review what we have here.…Starting on line 19,…we begin our create table statement…just like we did with the recipe entry table…except for this time we pass in the table name…associated with the recipe step entry.…
To begin, Annyce Davis reviews using the de facto data persistence solution available on Android: SQLite. She takes you through basic SQLite concepts—such as how to create a database wrapper and insert data into a table—as well as a few more advanced topics. Next, she covers working with Cupboard, an open-source project dedicated to simplifying your SQLite interactions. To wrap up, she dives into working with Realm, an object database solution designed with mobile devices in mind. Throughout the course, Annyce discusses establishing relationships between database tables, creating and running queries, as well as performing data migrations.
