Re: [PROGRAMMERING] [SQL] group by hjælp



Ja, man skal ind i noget self join, hvor pris bliver
udvælgelseskriteriet. Et eksempel:
select a.bogtitel, a.salgsted, a.pris from bog a, bog b where a.pris <
b.pris group by bogtitel;

Hmmm, det har jeg svært ved at se skulle virke. Måske virker det hvis der max er to priser for hver bog?

Men ellers...?
