Empty string

Databases
1

I have the following query to create a multi level drop down menu for events (region, county, city):


SELECT
  	P.province_eng  
	, CO.county_eng
	, C.city_eng
  FROM events E
	LEFT
  	JOIN provinces P 
    	ON E.province_id = P.province_id   
	LEFT
  	JOIN counties CO 
    	ON E.county_id = CO.county_id  
	LEFT
  	JOIN cities C 
    	ON E.city_id = C.city_id

  GROUP BY 
  			province_eng
      ,	county_eng
      , city_eng
  ORDER BY
  			province_eng
      ,	county_eng
      , city_eng

But I get an empty string for city_eng? This is one of my test inserts in the table events:


INSERT INTO `events` 
(`event_id`, `province_id`, `county_id`, `city_id`, `event_name_eng`, `event_name_gr`, `event_venue_eng`, `event_venue_gr`, `event_date`, `end_date`, `event_text_eng`, `event_text_gr`, `event_telephone`, `event_email`, `isPending`) 
VALUES
(13, 1, 3, 13, 'Test Name', NULL, 'Test Venu', NULL, '2011-01-03', NULL, 'Test', NULL, '26756 6543', 'yourmail@yourmail.com', 1);

As you can see there is a city_id present in the inser, but somehow It keeps giving me a empty string.

My guess is that id (13) isn’t present in the cities table

Hi Guido, unfortunately it is! That was my first of thought as well!

Really? Did you try that query in PHPMyAdmin (or whatever program you use to manage your database?
