Viewing Schema

Schema inspection helps you answer key questions fast: What columns exist? Which names are exact? What constraints are defined?

In SQLite CLI, .schema is the fastest entry point.

Core Concepts

Command	Use case
.schema	Show CREATE statements for all objects
.schema users	Show definition for one object

Code Examples

-- Show schema for everything in current database.
.schema

Expected output
One or more CREATE ... statements (or nothing in empty DB).

-- Show schema for a specific object name.
.schema users

Expected output
CREATE TABLE users (...) if it exists; otherwise no match output.

SQLite-Specific Nuances

SQLite Nuance

SQLite stores schema definitions as SQL text internally.

That is why .schema can print CREATE statements directly.

Common Pitfalls / Best Practices

Pitfall

Guessing column names before checking schema.

A small typo can produce confusing query errors.

Best Practice

Before writing a query on unfamiliar data, run .schema table_name first.

Quick Challenge

In any database with at least one table, run .schema and identify one exact column name you could query later.

View Solution

Example pattern:

.schema

Expected result
You can read exact object and column names directly from CREATE statements.
