Re: Doubt more info

Dave,

One typo in the code below:  'con.getMetaData()' should be
'con1.getMetaData()'.

The results I get when running against 7.2.1 with 7.2 driver is:

null null people id null null users people_id 0 3 3 people people_pkey 7
null null policy id null null users policy_id 1 3 3 policy policy_pkey 7

thanks,
--Barry
