How to list all tables

The SHOW TABLES command can be used to obtain a list of all tables:


To view the schema of an individual table, use the DESCRIBE command.

DESCRIBE nation;

The DESCRIBE command can also be used without a parameter to view all tables together with their columns and column types.


Below is an example of DESCRIBE without any parameters on the TPC-H dataset.

The SQL-standard information_schema views are also defined.

DuckDB also defines sqlite_master, and many Postgres system catalog tables for compatibility with SQLite and Postgres respectively.
