Harlequin

Harlequin is a SQL IDE that runs in the terminal. It has a data catalog,
a query editor with autocomplete and a results viewer. DuckDB and SQLite
work out of the box; the Postgres and MySQL adapters are included too.

Examples

harlequin ./my-data.duckdb

harlequin -a sqlite ./my-data.db

harlequin -a postgres "postgres://user:password@localhost:5432/mydb"

File access

Harlequin can use database files in your home directory. To also use USB
drives and other removable media (/media, /mnt), run:

sudo snap connect harlequin:removable-media
