How to Create a Table in SQLite

Basic Example

This example shows how to create a users table:

CREATE TABLE users (
    id INTEGER PRIMARY KEY,
    email TEXT
);

The resulting table has two columns:

• id (which is the table’s primary key)
• email

How to Create Non-Nullable Columns

You can create non-nullable columns by adding a NOT NULL constraint:

CREATE TABLE users (
   id INTEGER PRIMARY KEY NOT NULL,
   email TEXT NOT NULL
);

How to Create Columns With Default Values

CREATE TABLE users (
   id INTEGER PRIMARY KEY NOT NULL,
   email TEXT NOT NULL,
   credits_used INTEGER DEFAULT 0,
   subscribed_to_newsletter BOOLEAN NOT NULL DEFAULT 0
);

Here the following columns specify default values:

• credits_used with default value 0
• subscribed_to_newsletter with default value 0 (SQLite does not have a separate Boolean storage class. Instead, Boolean values are stored as integers 0 (false) and 1 (true)). This column is furthermore defined to be non-nullable.
