COUNT GROUP BY with active record

Question

I have a table with the following info   id     user id     points -------------------------- 1      12          48 2      15          36 3      18          22 4      12          28 5      15          59 6      12          31  etc    What I want is a top 10  array  with most entries per user id  order high to low   So using the table above I need the following array in return    12    3 rows 15    2 rows 18    1 row etc    How can I do this with CodeIgniter using the active record query method  Can this be done with COUNT and GROUP BY user id

I think you should count the results with FOUND ROWS   and SQL CALC FOUND ROWS  You ll need two queries  select  group by  etc  You ll add a plus select  SQL CALC FOUND ROWS user id  After this query run a query  SELECT FOUND ROWS    This will return the desired number

Although it is a late answer  I would say this will help you      query    this- gt db               - gt select  user id  count user id  AS num of time                 - gt group by  user id                 - gt order by  num of time    desc                 - gt get  tablename   10   print r  query- gt result

I believe you ll want something like this     this- gt db- gt select  user id  COUNT user id  as total      this- gt db- gt group by  user id       this- gt db- gt order by  total    desc       this- gt db- gt get  tablename   10     This will produce a result like      USER ID    TOTAL         12         3           15         2           18         1        UPDATE  As some pointed out in the comments the original query was summing the user ids rather than counting them  I ve updated the active record query to correct this
