関数はselect句（xxpay_util_element.get_run_result）から呼び出すように問合せをリライトする方法はありますが繰り返されてきているところwhere句は繰り返されず、一度だけ呼び出されます。

Answer 1

あなたがサブクエリとしてこのSQLを作成しようとすると、親クエリのWHERE句を追加することができます

Select * from (
    select 
     xxpay_util_element.get_run_result as get_run_result_1, --only fetch values here 
      ....... 
    from ..... 

) 
where get_run_result_1 ......... --add where clause here
