/** /**
* SQL Query being used: * Define the database query that is used to generate the stats table.
* This uses 1 of 2 possible queries, depending on $wgSpecialGadgetUsageActiveUsers.
*
* The simple query is essentially:
* SELECT up_property, SUM(up_value)
* FROM user_properties
* WHERE up_property LIKE 'gadget-%'
* GROUP BY up_property;
*
* The more expensive query is:
* SELECT up_property, SUM(up_value), count(qcc_title) * SELECT up_property, SUM(up_value), count(qcc_title)
* FROM user_properties * FROM user_properties
* LEFT JOIN user ON up_user = user_id * LEFT JOIN user ON up_user = user_id
