BorlandUser 您好..請參考以下文章

BorlandUser 你好 Delphi HELP中已說明的相當清楚? TSession provides global management of a group of database connections in an application. Unit DBTables Description Use TSession to manage a group of database connections within an application. There are three uses for TSession: standard, multiple net files for Paradox, and multi-threaded database applications. The library automatically creates a globally accessible default TSession component named Session for all database applications. The default session component handles standard database connections. An application can control the default session by accessing its properties, events, and methods at runtime. Database applications that must simultaneously access Paradox tables located in different network locations can establish multiple sessions, one for each network location. Finally, database applications that must establish multiple, concurrent connections to the same database, such as performing two queries against the same data at once, are multi-threaded applications. Multi-threaded applications must create and maintain one additional session component for each simultaneous connection to a single database server. Note: Applications that maintain multiple sessions can manage them through the TSessionList component. A default session list component, called Sessions?ote the plural which distinguishes it from the default session component, Session?s automatically created for all database applications. Note: TSession implements the IDBSession interface, which allows the global PasswordDialog function to supply passwords to the component.
