How to Create a Table in PostgreSQL
Here's an example of creating a
users table in PostgreSQL:
create table users ( id serial primary key, -- Auto incrementing IDs name character varying, -- String column without specifying a length preferences jsonb, -- JSON columns are great for storing unstructured data created_at timestamp without time zone -- Always store time in UTC );
create table users ( id serial primary key, name character varying not null, active boolean default true );
You can also create temporary tables that will stick around for the duration of your session. This is helpful to break down your analysis into smaller pieces.
-- Create a temporary table called `scratch_users` with just an `id` column create temporary table scratch_users (id integer); -- Or create a temporary table based on the output of a select create temp table active_users as select * from users where active is true;
