	Subclasses return an array of fields to order by here.

◆ getGroupName()

SpecialGadgetUsage::getGroupName ( )

◆ getQueryInfo()

SpecialGadgetUsage::getQueryInfo ( )

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) FROM user_properties LEFT JOIN user ON up_user = user_id LEFT JOIN querycachetwo ON user_name = qcc_title AND qcc_type = 'activeusers' AND up_value = 1 WHERE up_property LIKE 'gadget-' GROUP BY up_property;

Returns: array

◆ isExpensive()

SpecialGadgetUsage::isExpensive ( )

Is this query expensive (for some definition of expensive)? Then we don't let it run in miser mode.

$wgDisableQueryPages causes all query pages to be declared expensive. Some query pages are always expensive.

Returns: bool
