Using TTable

TTable encapsulates the full structure of and data in an underlying database table. It implements all of the basic functionality introduced by TDataSet, as well as all of the special features typical of table type datasets.

Because TTable is a BDE-enabled dataset, it must be associated with a database and a session. Once the dataset is associated with a database and session, you can bind it to a particular database table by setting the TableName property and, if you are using a Paradox, dBASE, FoxPro, or comma-delimited ASCII text table, the TableType property.

Note: The table must be closed when you change its association to a database, session, or database table, or when you set the TableType property. However, before you close the table to change these properties, first post or discard any pending changes. If cached updates are enabled, call the ApplyUpdates method to write the posted changes to the database.

TTable components are unique in the support they offer for local database tables (Paradox, dBASE, FoxPro, and comma-delimited ASCII text tables). The following topics describe the special properties and methods that implement this support:

In addition, TTable components can take advantage of the BDE's support for batch operations (table level operations to append, update, delete, or copy entire groups of records). This support is described in Importing data from another table.
