Question

Why is the following SQL query returning an error?

SELECT COUNT (DISTINCT rm.id) 
FROM ts_room rm
   LEFT JOIN ts_roomfacilities rf
      ON rm.id = rf.room_id
   LEFT JOIN ts_facilities f
      ON f.id = rf.facilities_id
   LEFT JOIN ts_building b
      ON rm.building_id=b.id;

It seems logical at first glance!

Here is my SQLFiddle – http://sqlfiddle.com/#!2/a59fc/20

Answer 1

Don’t put a space between COUNT and the first parenthesis. See it works now:

By the way, the error message you received at first tells you EXACTLY where your syntax error is.
