在 Node.js 上监听 Firebird 事件

Question

I created the following event in Firebird 2.5

CREATE TRIGGER neworc FOR ORC AFTER INSERT POSITION 0
AS
BEGIN
  POST_EVENT 'new_orc';
END

I would like to know if there is a way for me to listen for this event in my node application. I installed the node-firebird package and created the code below, but it didn't work.

Firebird.attach(options, function(err, db) {
    if (err)
        throw err;

    db.on('new_orc', function(result) {
        console.log(result);
    });
});

The documentation of node-firebird does not mention Firebird events. The on function only seems to be for node-firebird specific connection events ( "attach, detach, row, result, transaction, commit, rollback, error, etc." ), and not for Firebird events.

In other words, it looks like you cannot listen for Firebird events using node-firebird.

The drivers of https://github.com/asfernandes/node-firebird-drivers seem to support events (eg see this test ), but this library is severely underdocumented.
