When debugging CiviCRM pages, is there a native way to emit the SQL statements being run, eg on a Search page? I'm looking for something easier than finding the code for the page and putting in a debug_var kind of statement. I'd prefer to not have to rely on a Drupal module like cTools, since we work with other CMSes frequently these days.
If you want to see everything, you can enable MySQL logging as follows (don't do this on production!):
From the mysql console (or within an application like MySQL Workbench), run:
SET global general_log = 1; SET global log_output = 'table';
Look at all queries run within the last 15 seconds
select * from mysql.general_log where command_type = 'Query' and event_time > now() - interval 15 second;
Try to find queries on the civicrm_contact table
select * from mysql.general_log where argument like '%civicrm_contact%' and argument not like '%general_log%' order by event_time desc;
Clear the log
truncate table mysql.general_log;
Turn off logging
SET global general_log = 0;
in your civicrm.settings.php file, this might work based on a quick glance at the code.
The output will appear onscreen and in the CiviCRM log file (eg
If your page happens to be a report, you can install the Extended Reports extension which will display the full sql query being run.
