Subject: SQL Select help needed
It seems I am missing something obvious, however I can't figure out what.
I have two tables, 1-to-many related. Parent table contains car information,
child table contains the registration numbers, with their date, as they
change.
Parent table fields:
Id, Serial, Model
Child table fields:
Id, CarId, RegNumber, RegDate
How the heck the SQL that returns a list of the cars with their most recent
registration number looks like? I just can't figure it.
