2 calls to views_query_views_alter()
views_handler_relationship_groupwise_max::left_query in handlers/views_handler_relationship_groupwise_max.inc
Generate a subquery given the user options, as set in the options. These are passed in rather than picked up from the object because we generate the subquery when the options are saved, rather than when the view is run. This saves considerable time.
_views_query_tag_alter_condition in ./views.module
Replaces the substitutions recursive foreach condition.
