I have a table named LOCATIONS mapped to an entity named Location.

The SQL that works for me is as follows:

select ZipCode,sqrt( square(:latitudeValue - Latitude) + square(:longitudeValue - Longitude)) as distance from LOCATIONS order by distance

which, when I limit the returned list to single value, gives me the record I need.

What's the HQL equivalent? I'm just used to referencing entity properties...

just as an aside, it may be easier on the database (but check first) if you omit the sqrt in the SQL/HQL and apply it to the code afterwards.

Sorry, I posted a possible HQL in your other thread.

You can always also just stick with the SQL.

I like the HQL version though. Check your other thread.

Thanks

Mark

Thanks Mark. I'll close this one to prevent duplication.
