APEX Dictionary - Who uses a column in filters?

I just had the requirement to find out if some users have filters defined on a certain column of an interactive report.
First try was looking at the saved reports view in the application builder, but that didn't help.
And again the APEX Dictionary Views to the rescue.
Following query can be used to check if a column is used in a column filter or highlight.

SELECT r.created_by
     , condition_type
     , cond.condition_name
     , condition_column_name
     , cond.condition_operator
     , cond.condition_expression
     , cond.condition_expression2
     , cond.condition_display
  FROM apex_application_page_ir_cond cond JOIN
       apex_application_page_ir_rpt r
         ON r.application_id = cond.application_id
        AND r.page_id = cond.page_id
        AND r.report_id = cond.report_id
 WHERE cond.application_id = :application_id
   AND cond.page_id = :page_id
   AND cond.condition_column_name = :column_name
;

Note: It will not find column usage in a row filter.

May the APEX Dictionary be with you!
