EiffelStore Examples -------------------- Usage: book_insert This example illustrates how Eiffel users may access their selected DB to insert or modify objects in existing tables. An Eiffel object, say ``a book'', described by class BOOK, is inserted into a repository (instance of class REPOSITORY) defined with `db_book' access key for instance. The repository name should match an external RDB table named `db_book'. In example, session terminates on inexisting RDB table. Class DB_CHANGE encapsulates features supporting insertion statements. SQL insert statements insert new objects into existing repositories (i.e existing RDM tables). Class DB_CONTROL provides facilities to manage the session, control the DB status, and query the results.
