Question

I am trying to get the zip codes that are within a certain latitude and longitude and then using the zip codes returned pull all posts within the given area. The numbers for latitude and longitude are variables but for testing purposes they are hard numbers.
Can someone guide me in the right direction to make this work?

Query #1 – works selects post

SELECT user_id, session, zip, price, city, state, post_id, category, shortDesc,  fpi 
FROM post ORDER BY post.post_id DESC;

Query #2 – works selects zip codes in area

SELECT count(value) as duplicate, value 
from (SELECT DISTINCT zipcode as value from zip 
  WHERE latitude BETWEEN 27.747 AND 28.147 
  UNION all 
   SELECT DISTINCT zipcode FROM zip 
   WHERE longitude BETWEEN -82.657 AND -82.257) 
as tbl group by value having count(value) > 1;

Query as subquery

Tried: Failed

SELECT user_id, session, zip, price, city, state, post_id, category, shortDesc,  fpi 
FROM post 
WHERE zip = (
  SELECT count(value) as duplicate ,value 
  from (SELECT DISTINCT zipcode as value from zip 
    WHERE latitude BETWEEN 27.747 AND 28.147 
    UNION all SELECT DISTINCT zipcode FROM zip 
     WHERE longitude BETWEEN -82.657 AND -82.257) 
  as tbl group by value having count(value) > 1) 
ORDER BY post.post_id DESC;

error #1241 – Operand should contain 1 column(s)

Next Try: FAILED

SELECT user_id, session, zip, price, city, state, post_id, category, shortDesc,  fpi 
FROM post WHERE zip = (select distinct zipcode from zip 
  where latitude between 27.747 AND 28.147) 
  IN ( select distinct zipcode from zip 
    where longitude between -82.657 AND -82.257);

1242 – Sub query returns more than 1 row

Next Try: FAILED

SELECT user_id, session, zip, price, city, state, post_id, category, shortDesc,  fpi 
FROM post 
WHERE zip = ANY (
  select distinct zipcode from zip 
  where latitude between 27.747 AND 28.147) 
IN ( select distinct zipcode from zip 
     where longitude between -82.657 AND -82.257);

I’m not sure what you want

try this

select user_id, session, zip, price, city, state, post_id, category, shortDesc,  fpi 
FROM post WHERE zip in
(SELECT DISTINCT zipcode from zip where 
(latitude BETWEEN 27.747 AND 28.147) AND (longitude BETWEEN -82.657 AND -82.257))
