Re: [sqlite] Suggestion for syntax enhancement for virtual tables
If only the xDisconnect method is called on a virtual table create in the temp database at disconnect time, is that the only time xDisconnect will be called? The documentation at sqlite.org doesn't seem to say. Jay Krebich's Using SQLite says xDisconnect is "Called when a database containing a virtual table instance is detached or closed. Called once for each table instance." But looking at the SQLite code and comments, I'm not sure this is true. Is it? If so, it would be easy enough when writing a Virtual Table Module to note that it is being created in the temp database, and do any required cleanup in xDisconnect instead of xDestroy for that instance. But if xDisconnect can be called at other times, cleanup could be premature.

Re: [sqlite] Suggestion for syntax enhancement for virtual tables
Temporary virtual tables sounds like an interesting concept. Does the xDestroy() function get called on such a beast (as opposed to xDisconnect() when the connection is closed)? Should that function delete the backing store (even if a non-temporary virtual table is still connected)? -Ursprüngliche Nachricht- Von: Baruch Burstein [mailto:bmburst...@gmail.com] Gesendet: Donnerstag, 01.
