Question

I wonder whether someone may be able to help me please.

I’m using the query below to correctly retrieve Google marker data from a MySQL database.

SELECT l.locationid, f.locationid, l.locationname, l.osgb36lat, l.osgb36lon, count(f.locationid) as totalfinds 
  FROM detectinglocations as l 
  LEFT JOIN finds AS f ON l.locationid=f.locationid 
  GROUP BY l.locationid

I’m now trying to add to this by adding a where clause, to be more specific where userid='$userid'.

I’ve tried adding this extra clause in various positions within the query, and I’m sure that this is perhaps just a beginners mistake, but I just can’t get the query to work.

I just wondered whether someone could perhaps look at this and let me know where I’m going wrong.

Thanks and kind regards

Try adding the where clause right before GROUP BY.
