Hi all!
Sorry for the dumb question, but am I right in the following suggestion:
I have the following table:
create table tab_1 (
field_1 integer not null,
field_2 integer not null,
primary key (field_1, field_2));
Does it mean that this key requires unique COMBINATION of field_1 and
field_2? For example, at first I add:
insert into tab_1 values ('2', '3');
insert into tab_1 values ('3', '4');
Then I'd like to add the following:
insert into tab_1 values ('3', '2');
Here field_1 is NOT unique, but combination of field_1 and field_2 IS
unique. Will I get an error in this case?
Thanx for the answers!
