Description

Empty strings are allowed in composite primary keys, but not single-column primary keys.

Example:

create table bla (
pk text primary key,
val text
);

insert into bla (pk, val) values ('', '');

throws: Key may not be empty.

create table bla2 (
pk text,
pk2 text,
val text,
primary key ((pk, pk2))
);

insert into bla2 (pk, pk2, val) values ('', '', '');

succeeds
