Question

I have a query that I would like to exlude US States from. I am trying to find all data related to countries other than the US. I have the abbreviations for all the US States and can either link the table to the query and exlude them somehow or write a statement in the query to exlude them. But, I don’t know how to do either. I thought I could do Not “‘AK’, ‘IA’, ‘KY’, ‘WA'” but that isn’t working. Any suggestions?

Can you do something like this:

SELECT * from table1 as t1
LEFT JOIN StatesTable as st
ON t1.State = st.State
WHERE st.id is null

You can also use NOT IN but i think that is a performance no-no. Example:

SELECT * FROM table1 where State NOT IN
   (SELECT State from StatesTable)
