No, different SQL. I think I had to use raw to get the queryfield display template to work. I tried the "[cb:userfield..." just now and it displays nothing.
The first query field is
SELECT reward_date, points, reward_for FROM `#__user_points_history` WHERE `user_id` = '[user_id]';
and DISPLAY output is template pointing to my file under "table" ( a nicely formatted HTML table )
2nd query field is
SELECT star_date, stars, star_for FROM `#__user_stars_history` WHERE `user_id` = '[user_id]';
and DISPLAY output is template pointing to my file under "table2"
The nicely formatted HTML table has a heading with user-friendly column headings which are different between table and table2. That's how I can tell it is using the wrong one.
