Description
The DBC_CLOSEDATA database event is triggered by the closure of a database. The associated code is run before the database is actually closed. Databases are closed using the CLOSE DATABASES command.
| Event | Description |
|---|---|
| <expC> | The database name |
| <expL1> | Specifies whether the ALL keyword was included on the CLOSE DATABASES, .T. or not, .F. |
| <expL2> | If the dbc_closedata procedure returns .F., the database is not closed, if .T., the close operation continues |
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.
Programs associated with database events should reside in the DB_DATADIR sub-directory for the relevant database.
Example
procedure dbc_closedata lparameters cName, lAll close procedures return
