SUMMARY

Linked (attached) tables, such as Microsoft Access, Paradox, Btrieve, FoxPro, or dBASE tables, are different from native Microsoft Access tables in four ways:

  • In the Database window, the icons for linked tables contain black arrows.
  • If you try to open a linked table in Design view, you receive the following message.

    In Microsoft Access 7.0 and 97:

    Table 'xxxxx' is a linked table. Some properties can't be modified. Do you want to open it anyway?

    In Microsoft Access 1.x and 2.0:

    Table 'xxxxx' is an attached table. Some properties can't be modified. Open it anyway?"

  • When you delete a linked table, its contents are not deleted. Only the table entry is deleted.
  • You can define relationships between linked tables and native Microsoft Access tables, or between linked non-Microsoft Access tables and native Microsoft Access tables, but you cannot enforce such relationships.

    You can create relationships between a linked Microsoft Access table and a native Microsoft Access table.
