One of our customers wants to view transition for a certain page, using also segment based on events.

As we know, there is a limitation that when segment is based on events, there are no reports for other kinds of actions. To bypass it, customer defined a goal by "send an event", after that he created a segment on "Visit converted for specific Goal ID".

Problem is that if he wants to open the transition for a certain page (using segment as above), he got the following error message: _SQLSTATE[23000]: Integrity constraint vilation: 1052 Column 'idactionurl' in field list is ambigous.


Seems that wrong SELECT was generated, using segments and transitions as described above. Customer is using Piwik 2.15.0.

I can reproduce it. This is the query that is eg failing (possibly also other queries in transitions API)


                    WHEN counter = 6 THEN 'Others'
                    ELSE `name`
                END AS `name`
                    WHEN counter = 6 THEN 'Others'
                    ELSE `url_prefix`
                END AS `url_prefix`

                , `type`, sum(`3`) AS `3`
            FROM ( 
                `name`, `url_prefix`,

                WHEN `type` = 1 AND <a class='mention' href='https://github.com/counter1'>@counter1</a> = 6 THEN 6
                WHEN `type` = 1 THEN <a class='mention' href='https://github.com/counter1'>@counter1</a>:=<a class='mention' href='https://github.com/counter1'>@counter1</a>+1
                WHEN `type` = 8 AND <a class='mention' href='https://github.com/counter8'>@counter8</a> = 6 THEN 6

                if ( idaction_url IS NULL, idaction_name, idaction_url ),

                piwik_log_link_visit_action AS log_link_visit_action

                AND log_link_visit_action.idsite IN (?) AND log_link_visit_action.idaction_url_ref = 1525 AND (log_link_visit_action.idaction_url IS NULL OR log_link_visit_action.idaction_url != 1525) )
                ( log_conversion.idgoal = ? )
            GROUP BY
                if ( idaction_url IS NULL, idaction_name, idaction_url )
            ORDER BY
                `3` DESC ) actualQuery
         ) AS withCounter
            GROUP BY counter, `type`

We can possibly fix the error by prefixing idaction_url. Not sure if it will break anything.
