Description
The DROP DATABASE command removes the specified database and all its tables. The number of files deleted from the database is returned. An error occurs if the database does not exist unless the IF EXISTS clause is specified.
Databases in Recital are implemented as directories containing files that correspond to the tables and associated files in the database. Operating System file protection can be applied individually to the files for added security. The directories are sub-directories of the Recital data directory. The environment variable DB_DATADIR points to the current Recital data directory and can be queried using the GETENV() function. Files from other directories can be added to the database using the ADD TABLE command or via the database catalog and SET AUTOCATALOG functionality.
Example
DROP DATABASE temp
Products
Recital Server, Recital
