Select rows which are not present in other table

Question

I\'ve got two postgresql tables:

table name     column names
-----------    ------------------------
login_log             


        

Answer 1

A.) The command is NOT EXISTS, you're missing the 'S'.

B.) Use NOT IN instead

SELECT ip 
  FROM login_log 
  WHERE ip NOT IN (
    SELECT ip
    FROM ip_location
  )
;
