Commands

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 client/server environment is used, some permissions may be needed to execute a specific command.

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.
