No. The only way to do that would be to construct a 'server wrapper' around sqlite and have applications (clients) connect to that server. It has been done before, for example, there is an ODBC wrapper. http://www.sqlite.org/cvstrac/wiki >3. Can multiple threads or applications access simultaneously > the same in-memory sqlite database? Not without the server mechanism. The performance gain of a :memory: database is limited, one of the reasons is that most operating systems will cache the database file in memory anyway. In general: when you really need a DB server, don't use SQLite. http://www.sqlite.org/whentouse.html >Thank you.
