Google bigquery 此BigQuery搜索错误的原因是什么？

下面是错误消息：语法错误：表值函数调用的每个子查询参数必须用括号括起来。若要修复此问题，请替换并选择。。。选择。。。在[3:1]

中，所讨论的查询是用BigQuery遗留SQL编写的，因此请确保在遗留模式下运行它。第二，下面的版本有一些小的修正，在REGEXP\u REPLACE中错误地使用了双引号而不是撇号

   SELECT a.name, b.name, COUNT(*) as count
   FROM (FLATTEN(
   SELECT GKGRECORDID, UNIQUE(REGEXP_REPLACE(SPLIT(V2Persons,';'), r',.*', ")) name
   FROM [gdelt-bq:gdeltv2.gkg]
   WHERE DATE>20150302000000 and DATE < 20150304000000 and V2Persons like '%Tsipras%'
   ,name)) a
   JOIN EACH (
   SELECT GKGRECORDID, UNIQUE(REGEXP_REPLACE(SPLIT(V2Persons,';'), r',.*', ")) name
   FROM [gdelt-bq:gdeltv2.gkg]
   WHERE DATE>20150302000000 and DATE < 20150304000000 and V2Persons like 
   '%Tsipras%'
   ) b
   ON a.GKGRECORDID=b.GKGRECORDID
   WHERE a.name<b.name
   GROUP EACH BY 1,2
   ORDER BY 3 DESC
   LIMIT 250
