Solution 1

you can't get the result of a trigger, it's executed inside the DB, without you calling it, so there's no where for it to come back to you. A trigger is useless here, it's a dumb thing to do. A trigger should act after an insert to perform a DB operation. If you're wanting to get this data, do a stored proc and call it, or do your insert in a proc that also calls this, so you can get the data back and show it.
