Hello experts,

I have two tables that have similar demographic info, but are without any primary keys or identifiers.  I have a need to find all of the records in the person table, that do not exist on the subscriber table.  They have similar columns, but are named a little different - same datatypes though.  Here is my script, and I'm having trouble with the syntax, as I am not sure which column to join on.  I need to make sure that lastname, firstname, and date_of_birth are the three pieces of data that dont match in the other table:

select n.subscriber_firstname, n.subscriber_lastname, n.subscriber_date_of_birth, n.SUBSCRIBER_SSN
from NGC_SUBSCRIBER n
left join person p
on n.SUBSCRIBER_SSN = p.ssn
where n.SUBSCRIBER_LASTNAME <> p.last_name
and n.SUBSCRIBER_FIRSTNAME <> p.first_name
and n.SUBSCRIBER_DATE_OF_BIRTH <> p.date_of_birth
and p.last_name is null

Thoughts?

Thanks!

You say you want the data from the persons table that doen't exist in the subscriber table
but your query

select n.subscriber_firstname, n.subscriber_lastname, n.subscriber_date_of_birth, n.SUBSCRIBER_SSN
from NGC_SUBSCRIBER n
left join person p
on n.SUBSCRIBER_SSN = p.ssn
where n.SUBSCRIBER_LASTNAME <> p.last_name
and n.SUBSCRIBER_FIRSTNAME <> p.first_name
and n.SUBSCRIBER_DATE_OF_BIRTH <> p.date_of_birth
and p.last_name is null


is returning the subscriber data, should it not be the p.last_name, p.first_name, p.date_of_birth?
