This page lists all database commands that are supported by BaseX. Database commands can be either run from the Command Line, the Language Bindings, JAX-RX, the input field in the GUI, or in many other ways.

If the GUI is used, all commands that are triggered by the GUI itself will show up in the Info View. A short version exists for some command arguments. For example, you may replace the DATABASE keyword with DB.
