Google专利中的优先权申请与要求优先权的申请有什么区别？

Question

我想在“要求优先权的申请”中按申请号计算正向引用次数。下面可以通过使用优先应用程序中的应用程序来实现目的。谁可以帮我纠正它？

SELECT 
  c.publication_number AS Pub, 
  COUNT(DISTINCT REGEXP_EXTRACT(p.publication_number, r'(.+-.+)-')) AS CitedByCount
FROM `patents-public-data.patents.publications` AS p, 
UNNEST(citation) AS c 
WHERE c.publication_number IN (
  SELECT publication_number 
  FROM `patents-public-data.patents.publications`
  WHERE application_number IN ('CN-201510747352-A') 
)
GROUP BY c.publication_number
