- Simple classes for using SQLite's exec and get_table.
-
- TSQLiteDatabase wraps the calls to open and close an SQLite database.
- It also wraps SQLite_exec for queries that do not return a result set
-
- TSQLiteTable wraps sqlite_get_table.
- It allows accessing fields by name as well as index and can step through a
- result set with the Next procedure.
