I have loaded over 29,000 customer records into a database. I'm trying
to apply a referential foreign key that validates the country code and
the province code in another table. It won't work because somewhere in
that 29,000 records there is a province code or country code that
doesn't match. Is there a way to use a select statement to find out
which customer records has the invalid data? Here is the partial table
layout:
cust province
-------- -------
country ===> country
province ===> code
Thanks in advance...
