Subject: Re: Vandræðagangur með lið 3 Author: No name [ Next Thread | Previous Thread | Next Message | Previous Message ] Date Posted: 21:35:06 05/Nov/2007 In reply to: 's message, "Vandræðagangur með lið 3" on 17:28:29 02/Nov/2007 Ég lenti í þessu við lausn síðasta reikniverkefnis. Ég mæli með að þú chekkir á : http://www.redhat.com/docs/manuals/database/RHDB-7.1.3-Manual/prog/plpgsql-description.html Þar stendur þetta um Reccords : " Records name RECORD; Record variables are similar to rowtype variables, but they have no predefined structure. They take on the actual row structure of the row they are assigned during a SELECT or FOR command. The substructure of a record variable can change each time it is assigned to. A consequence of this is that until a record variable is first assigned to, it has no substructure, and any attempt to access a field in it will draw a runtime error. Note that RECORD is not a true datatype, only a placeholder. Thus, for example, one cannot declare a function returning RECORD.
