- CH 13 − SUBSET DATABASES
- ========================
- Subset databases are fully-working Powerbase databases with exactly the same
- structure as the main database but containing only a selection from its
- records.
-
- Creating a subset is extremely simple. Choose Export subset from the main
- menu and you will see a window strongly resembling the one used to export
- CSV files. It features our old friend the Query panel into which you type a
- search formula which determines the records to be exported as a subset.
-
- It is then only necessary to enter a suitable filename and drag the database
- icon to a filer window. The default pathname creates the new database as
- !Subset in PrintJobs and you can accept this default by just clicking on
- Export or typing Return.
-
- On opening the new database you will find that it functions exactly like the
- original but contains only the selected records. It is made just large
- enough to contain the selected records so you will need to increase its
- length (see 10.5) if you intend to add any further records.
