Step 1: Database SchemaΒΆ

First we want to create the database schema. Only a single table is needed for this application and we only want to support SQLite so creating the database schema is quite easy. Just put the following contents into a file named schema.sql in the just created flaskr folder:

drop table if exists entries;
create table entries (
  id integer primary key autoincrement,
  title text not null,
  text text not null

This schema consists of a single table called entries and each row in this table has an id, a title and a text. The id is an automatically incrementing integer and a primary key, the other two are strings that must not be null.
