I have a table country with a lookup table to country_type.
table country
country_id (pk), col2, col3, country_type_id (fk) integer
lookup table
country_type country_type_id (pk), type_name varchar
My lookup
table has 50 country types, but only 20 are 'in use' in the
current db (with the rest possibly used later as the db expands). On the webpage I am
creating (I am using a php generator) I can set it up to add a filter by country type based on the
country type_name varchar - so one can view the country types by name rather than the id integer - but all 50 types are listed.
I only want the
20 that currently 'in use' (not sure if this is the best way to describe it) and therefore relevant to searches/filters (i.e. I don't want
to see a "There are no records to display" message).
What WHERE condition can I use to achieve this?
