Hello !
I have two tables with identical schema. I want to copy all data from
Table A to Table B, but table B might already have some of table A:s
data (each record is identified using record_numbers). I would suspect
this can be accomlished using a 2 stage query, first performing a join
of some kind and then the copying. But I have little to no clue on how
to make it happen.
Any ideas ?
Thanks a lot !
