This is the line that create the violation:
sprintf(s, "insert into a values(%d, 'The name field for %d', %d)",
NROWS+i, i, NROWS+i+VIOLATION);
if VIOLATION is 0 then you are inserting a record with id = NROWS+i and aid =
NROWS+i. Since the referential constraint is that aid references id in the
same table, it is satisfied by the record itself, thus the constraint is not
violated.

lot about anticipated traffic volume.
