Description

The REINDEX DATABASE command rebuilds the indexes for each table in the active database.

Databases in Lianja 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 Lianja data directory. The environment variable DB_DATADIR points to the current Lianja 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. Databases are opened using the OPEN DATABASE command.

If the <database name> is specified, the REINDEX DATABASE command will operate on the specified database's catalog file: the catalog's index tags will be rebuilt. If the question mark, '?', is included instead of the <database name>, the 'SELECT A FILE' dialog will be displayed, allowing the user to select the database. The dialog defaults to the DB_DATADIR directory.


Example

open database southwind
reindex database
close databases
reindex database southwind
