The documentation says that the function sqlite3_update_hook() is called
whenever a row is updated, deleted or inserted for a rowid table. But I
don't find this function to be invoked in my program. When will this
function be invoked??
And I am

No. It says that this function is called to register a callback
function that is called for these updates.

Thanks Dennis for your reply.
I would like to avoid triggers for performance reasons.
I haven't found an official solution so I am implementing my own
sqlite3_update_notify API that is executed before the operation takes
place.

When i call sqlite3_update_hook() from App "A" and point it to my
callback, i am only notified when app "A" updates the database.
When app "B" (another instance of the same app as "A") updates the
database, app "A"'s callback is never called, and vice versa.
I thought the whole point of
Hello,
I'm trying to use the update hook functionality. I have lookup (aka
join) tables that provide many-to-many relationships between rows in
other tables. The problem is when I get the delete notification for the
join tables the rowid is not useful in that context. I really need to
know the
Make the hook queue a GUI update transaction and execute those
transactions following the COMMIT. Discard the list of GUI update
transactions on a ROLLBACK.

when a database change is detected. But during testing, I encountered
some problems with this approach together with transactions.

Cameron,
Then you should be able to execute the following SQL query in your
sqlite3_update_hook handler
The rowid of the table's record in the sqlite_master table would be
great, but really any unique integer that I can later use to get the
table's name would be fine.
