# 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.
