I use Delphi 6
I have several questions:
1.
Are first column indexs in the table (when is opened in DatabaseDesktop)(or maybe they are only row number)?If not, what are indexs?What is the first first column else. See squared part in the upload files .
2.
is this code posssible and how to create table which have:
create table ponudi(
S# number referneces snabduvaci(s#),
on delete set null
on update cascade
pr# number(5),
v# number(2),
kolicina_nar varchar,
datum-nar date,
check(kolicina_nar in('london','paris','rim')),
constraint foreign key(pr#,v#)
references prizvodi (proizv#,vid#)
