# Explore The Database Schema
The first thing I like to do when connecting to a database is get a quick lay
of the land. What are the tables and what do they look like?
I can list all tables with the `.tables` dot-command.
```sql
sqlite> .tables
ingredient_amounts ingredients recipes
```
I can then look at the `create table` statement for specific tables to see what
their schema looks like:
```sql
sqlite> .schema recipes
CREATE TABLE recipes (
id integer primary key,
name varchar not null,
description text not null,
instructions text not null
);
```
The `.schema` dot-command can also be used without any argument and it will
display the schema for all tables of all connected databases.
Run `.help` from the `sqlite3` prompt for more dot-command options.
