Question

The base zip code used in this query is the lat/lng for 90210 which has an average agi (for 2008) of over $400k. I don’t expect it to show up in this output because of the BETWEEN range of 100000 and 200000.

SELECT 
  zip, city, state, avg_agi, 
  ( 3959 
      * acos( 
              cos( radians(34.088808) ) 
            * cos( radians( lat ) ) 
            * cos( radians( lng ) - radians(-118.40612) ) 
            + sin( radians(34.088808) ) 
            * sin( radians( lat ) ) 
        ) 
  ) AS distance 
FROM 
  zip_codes, avgagi 
where 
      zip=zipcode 
  and avg_agi BETWEEN 100000 and 200000 
HAVING 
  distance < 5 ORDER BY distance LIMIT 0 , 10000;

However, for my application I need it to include the base zip code in the output. It was suggested I use a WHERE with OR for zip=”90210″, however I’m having a very difficult time figuring out how to make that work. When I try to incorporate that suggestion it spins for the longest time and never comes back.

How can I modify the above MySQL query to have it include the zip code of 90210, regardless of the BETWEEN ranges. Thanks!

Probably easier to use a UNION statement:

SELECT 
  zip, city, state, avg_agi, 0 AS distance 
FROM 
  zip_codes, avgagi 
where 
      zip=zipcode 
UNION
SELECT 
  zip, city, state, avg_agi, 
  ( 3959 
      * acos( 
              cos( radians(34.088808) ) 
            * cos( radians( lat ) ) 
            * cos( radians( lng ) - radians(-118.40612) ) 
            + sin( radians(34.088808) ) 
            * sin( radians( lat ) ) 
        ) 
  ) AS distance 
FROM 
  zip_codes, avgagi 
where 
      zip=zipcode 
  and avg_agi BETWEEN 100000 and 200000 
HAVING 
  distance < 5 ORDER BY distance LIMIT 0 , 10000;

otherwise try this:

SELECT 
      zip, city, state, avg_agi, 
      ( 3959 
          * acos( 
                  cos( radians(34.088808) ) 
                * cos( radians( lat ) ) 
                * cos( radians( lng ) - radians(-118.40612) ) 
                + sin( radians(34.088808) ) 
                * sin( radians( lat ) ) 
            ) 
      ) AS distance 
    FROM 
      zip_codes, avgagi 
    where 
          zip=zipcode 
    AND(zip = 90210
    OR avg_agi BETWEEN 100000 and 200000 )
    HAVING 
      distance < 5 ORDER BY distance LIMIT 0 , 10000;
