Following on from my query here How to write custom report SQL

(CiviCRM 4.7 on WordPress)

I built the SQL I needed as step 1, which works fine in mysql / phpmyadmin.

I have used civix, to generate a module and to clone the 'empty' report from 101 and register the report - so far so go, if I want a report that says 'hello'.

Next step slot in my SQL and test .... and within civi it gives sysntax errors.

Debug shows that it is inserting SQL_CALC_FOUND_ROWS all over the SQL, where as I need it only on the final select.

Although my requirement is simple my SQL is complex, and I can't achieve it in one SELECT statement ( maybe possible by a SQL wizard ), as it requires contact relationships in two directions and a 'pivot' of contributions, it builds 3 temporary table and joins them up in a final select.

My main question is 'can CiviReport only handle a single select?' and the second question is is there something I can do, or should I just resort to coding outside CiviReport structures?

Thanks so far for the help given, it has been fantastic.

Eaxmple issue

CREATE TEMPORARY TABLE tmpcontrhist AS
   SELECT SQL_CALC_FOUND_ROWS house_id,
     YEAR(contr.receive_date) memb_year,
        contr.total_amount memb_amount
FROM
   tmpareareps,
   civicrm_contribution contr
WHERE
   house_id = contr.contact_id;


Database Error Code: You have an error in your SQL syntax; check the manual      that corresponds to your MySQL server version for the right syntax to use near    'CREATE TEMPORARY TABLE tmpcontrhist AS SELECT SQL_CALC_FOUND_ROWS house_id, ' at line 21, 1064

In the CRM/Report folder: grep -r -i "TEMPORARY" *

This gives you some existing reports that use temp tables which you can look at to get some ideas.

Form/Activity.php Form/Contribute/Detail.php etc...

  • Gosh, this is far harder than slotting in a bit of SQL and away you go! Need to learn a whole new framework for a one off. Not sure if it is etiquette but any one want to quote to code this up - I can provide working SQL, or if this isn't the right place - apologies - and advise :) – Alan Fuller Sep 22 '16 at 16:03
  • Take a look at "custom search" instead. You don't have all the widgets but you can just plug in your sql. wiki.civicrm.org/confluence/display/CRMDOC/… – Demerit Sep 22 '16 at 16:11
  • Thanks, an easier starting point. By the way any reason why in the example I looked at the buildtemptables was called in the from function rather than select - answering my own question maybe select deals with columns, and in the case in looking at the temp table logic requires stuff that isn't available that early. – Alan Fuller Sep 22 '16 at 16:22

Maybe I have a limited MySQL knowledge, but I think you need to join the two tables? So I would do something like

FROM tmpareareps tmp JOIN civicrm_contribution_recur recur ON tmp.house_id = recur.contact_id
  • 1
    The SQL join fine. I could use JOIN or just use the WHERE, it has the same impact, the issue is CiviCRM ADD the SQL_CALC_FOUND to the SELECT which is invalid in the CREATE TEMPORARY TABLE AS.. The code I provide to Civi does not have SQL_CALC_FOUND in it. – Alan Fuller Sep 22 '16 at 12:04
