Template:Query no qualifier

Template documentation

Partial query to get values of statements of some given property that has no qualifier at all, or to filter item if they have such a statement.

Variable naming

The statement is named by default by the pattern ?<item>_<property>_statement and the value ?<item>_<property>_value.

Usage

• {{query no qualifier|item=?class|property=number|value=?number_of_instances}}
  

 ?class p:P1114 ?class_number_statement .
?class_number_statement ps:P1114 ?number_of_instances .
FILTER NOT EXISTS {
   ?class_number_statement ?classnumberpq_pred [] . # a triple involving our statement ...     
   [] wikibase:qualifier ?classnumberpq_pred .                                                        # ... with a predicate ?pq_pred that is a qualifier

}

In context:

select ?class ?number_of_instances {
 # get all the classes with an unqualified "number" statement, the cardinality of the class
  ?class p:P1114 ?class_number_statement .
 ?class_number_statement ps:P1114 ?number_of_instances .
 FILTER NOT EXISTS {
    ?class_number_statement ?classnumberpq_pred [] . # a triple involving our statement ...     
    [] wikibase:qualifier ?classnumberpq_pred .                                                        # ... with a predicate ?pq_pred that is a qualifier
}
}
