How Can I View Detailed SQLite Table Information Like MySQL's DESCRIBE Command?

Examining Table Details in SQLite

When working with a relational database, examining the details of its tables is often crucial. In MySQL, the DESCRIBE [table] command provides comprehensive information about a given table. However, SQLite users may wonder if there's an equivalent command.

SQLite Table Inspection

Unlike MySQL, SQLite does not have an exact equivalent to the DESCRIBE command. However, the PRAGMA table_info [table] command can provide some basic information about the table structure. However, it lacks details such as field types or constraints.

Detailed Schema Retrieval

To obtain more comprehensive information about a SQLite table, the SQLite command line utility provides a viable option. The .schema TABLENAME command outputs the SQL statements used to create the table, including its columns, datatypes, constraints, and indexes.

Example:

sqlite> .schema users
CREATE TABLE users (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    name TEXT NOT NULL,
    email TEXT UNIQUE,
    created_at DATETIME NOT NULL
);
Copy after login

This command displays the full schema of the "users" table, including its column names, datatypes, constraints, and the AUTOINCREMENT property for the "id" column.
