Hello,
The following SQL works as I expect -
sqlite> CREATE TABLE edges(parent int, child int, primary key(parent,
child));
sqlite> insert into edges select null, 1;
sqlite> select * from edges;
parent child
1
sqlite>
but if I remove the superfluous rowid column from the table definition -
sqlite> drop table edges;
sqlite> CREATE TABLE edges(parent int, child int, primary key(parent,
child)) without rowid;
sqlite> insert into edges select null, 1;
Error: NOT NULL constraint failed: edges.parent
sqlite>
Why do I get this error?
