Description

The REBUILD DATABASE command rebuilds the catalog for the active or specified database. This packs the catalog file and rebuilds its index tags. All valid programs, tables and known associated indexes from the database's directory are added into the catalog.

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 / symbol 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. Databases are opened using the SQL OPEN DATABASE command.

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. This is only applicable for Recital Terminal Developer: for Recital Database and Mirage Servers, the <database name> must be specified.

Example

VFP/SQL> rebuild database
VFP/SQL>close databases
