After you create a database, you can associate tables with a database by creating them in the database or adding existing ones. Tables can belong only to one database at a time; therefore you can associate any table that is not currently part of another database. If you want to associate a table that belongs to another database, you must remove that table before you can add it to a different database. You can also use data from another database table without removing it. For more information, see How to: Use Tables from Other Databases.

Note:
To associate free tables with a database, you must explicitly add them. Modifying their structure does not associate free tables with a database, even if a database is open when you modify the structure.

When you add a table to a database, Visual FoxPro modifies the header record in the table file to document the path and file name for the database that now contains the table. This path and file name information is called a back link because it links the table back to the owning database.

To create database tables, see How to: Create Database Tables.

To associate a table with a database in a project
