I don't know method to set triggers on begin and commit transaction events.
For example:
CREATE TABLE groups
(
id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,
save_date REAL,
update_date REAL,
delete_date REAL NOT NULL DEFAULT '',
name TEXT COLLATE russian UNIQUE NOT NULL DEFAULT ''
);
create trigger groups_insert after insert on groups begin
SELECT notify_insert('groups', NEW.rowid, NEW.id, NEW.save_date,
NEW.update_date, NEW.delete_date, NEW.name);
update groups set save_date = coalesce(save_date,
julianday('now')),update_date = julianday('now') where rowid=NEW.rowid;
end;
create trigger groups_update_after after update on groups begin
update groups set update_date = julianday('now') where rowid=OLD.rowid;
SELECT notify_update('groups', NEW.rowid, NEW.id, NEW.save_date,
NEW.update_date, NEW.delete_date, NEW.name);
end;
In my log I get lines as:
DATABASE NOTIFY UPDATE table=groups rowid=1003646
1003646 2454528.5 2454704.97969 {group_name}
...
(and I'm saving log records to another SQLite database).
Best regards, Alexey.
