Answer 1

你错过了一个逗号并将你移到了小组前的哪个地方

Select 
    count(*) ,  
    a.entity_id
FROM pcspro.bas2016_process_and_verify a,
    pcspro.bas2016_mailout_return b,
    pcspro.bas2016_universe c
WHERE a.entity_id = b.entity_id
    AND b.entity_id = c.entity_id
    --AND c.entity_id = a.entity_id --no need
AND STATUS IS NOT NULL AND ENTITY_REPORTED_STATUS = 'W' 
GROUP BY a.entity_id

Answer 2

您应该在ANSI SQL中重写您的查询：

Select count(*),
       entity_id
FROM pcspro.bas2016_process_and_verify a
   INNER JOIN pcspro.bas2016_mailout_return b
      USING(entity_id)
   INNER JOIN pcspro.bas2016_universe c
      USING(entity_id)
WHERE STATUS IS NOT NULL
  AND ENTITY_REPORTED_STATUS = 'W'
GROUP BY entity_id;
