Hi, I've a problem creating a table. My Sql
instruction is:
CREATE TABLE questiontypes (
id integer NOT NULL,
flags integer,
label text,
UNIQUE (id,flags)
);
Is it ok?? I must have 'flags' like to NULL... but
'id' is NOT NULL...
Now if I insert a row:
INSERT INTO questiontypes (id,flags,label) values
(2,null,'a');
and re-insert it... I can!!!! Now there are two
identical row, and UNIQUE??
I think postgres must occur an error? Is it Ok?
(The same problem is with:
INSERT INTO questiontypes (id,label) values (2,'a');
Is it ok?)
Thanks you, Mauro
