QUESTION
I am using the set_update_hook()
function in the karellen-sqlite Python module to automatically send database changes to a function. Basically, it works like this:
ANSWER
Answered 2017-Aug-11 at 11:33That mechanism is a wrapper around the sqlite3_update_hook() C API function:
The first argument to the callback is a copy of the third argument to
sqlite3_update_hook()
. The second callback argument is one ofSQLITE_INSERT
,SQLITE_DELETE
, orSQLITE_UPDATE
, depending on the operation that caused the callback to be invoked. The third and fourth arguments to the callback contain pointers to the database and table name containing the affected row. The final callback parameter is the rowid of the row. In the case of an update, this is the rowid after the update takes place.
So you get just enough information to identify the row.
