Huh? Did you remember to commit between deleting and defining the
primary key? Deleting is DML and defining keys are DDL, and they
should never be mixed.

I cannot think of any other reason for this to fail (I think Claudios
document should be old enough for IB 5.6 - I think he wrote it around
the time IB 6.0 appeared), so if it is any other reason I cannot help
you (though Ann and a lot of others probably can).
