wemustdesign Posted July 20, 2011 Share Posted July 20, 2011 I have 3 tables for my website, Locations, Attractions and Location_Attractions (stores which attractions can be found at the different locations) I am Locations id name 1 Las Vegas Attractions id name 1 Casino 2 Hotel Location_Attractions location_id attraction_id 1 1 1 2 trying to get my head round how I perform a query to show which locations a certain attraction can be found at. For example on the Casino page I am going to list oll of the locations this can be found at. So I know I need to query Location_Attractions to find all of the locations that have the correct attraction_id (eg 1 for Casino). I then need to link this to the Locations table to retrieve the details about the locations (such as name, address). Any idea how I would do this, would I use a JOIN?

AyKay47 Posted July 20, 2011 Share Posted July 20, 2011 since the number of fields are the same in each table, you can actually use a Union here Link to comment https://forums.phpfreaks.com/topic/242477-query-question/#findComment-1245357 Share on other sites More sharing options...
DavidAM Posted July 20, 2011 Share Posted July 20, 2011 This is no place for a UNION. This requires a 3-table JOIN, which AbraCadaver posted for you in your original topic: http://www.phpfreaks.com/forums/index.php?topic=339140.msg1598717#msg1598717 Link to comment https://forums.phpfreaks.com/topic/242477-query-question/#findComment-1245358 Share on other sites More sharing options...
AyKay47 Posted July 20, 2011 Share Posted July 20, 2011 it depends on how the OP wants the data displayed, perhaps I am misunderstanding the goal here Link to comment https://forums.phpfreaks.com/topic/242477-query-question/#findComment-1245359 Share on other sites More sharing options...
