Re: [PROGRAMMERING] Den tomme mængde i SQL.





select * from table where id in (join(",",@ids));

Hvilket netop ikke giver mig det forventede tomme resultatsæt i
situationen hvor @ids er tomt, men virker fint i alle andre tilfælde.

Kan du ikke lade @ids altid indeholde et id, du ved ikke forekommer i tabellen? Måske et negativt tal?
Måske et lousy hack, men det vil virke...
