PostgreSQL在按created\u搜索时结果不正确

需要括号:

WHERE (sr.created_at >= '2005-07-01T08:00:00+00:00' AND 
       sr.created_at <= '2005-08-02T07:59:59+00:00'
      ) AND
      (4 IS NULL OR sr.client_id = 4) AND 
      (NULL IS NULL OR f.id = NULL)

虽然没有必要,但我将使用带有tz的显式时间戳编写tis,并将逻辑简化为:

WHERE (sr.created_at >= '2005-07-01T08:00:00+00:00'::timestamptz AND 
       sr.created_at < '2005-08-02T08:00:00+00:00'::timestamptz
      ) AND
      (4 IS NULL OR sr.client_id = 4) AND 
      (NULL IS NULL OR f.id = NULL)

有多个AND和一个OR使where子句起作用,

SELECT
  COUNT(sr.id) AS total,
  COUNT(sr.id) FILTER (where (raw #>> '{survey, declined}' IS NULL) OR (raw #>> '{survey, declined}' = 'false')) AS completed,
  COUNT(sr.id) FILTER (WHERE (raw #>> '{survey, declined}' = 'true')) AS denied
FROM survey_results sr
LEFT JOIN clients c ON c.id = sr.client_id
LEFT JOIN facilities f ON f.client_id = c.id
WHERE
    (sr.created_at >= '2005-07-01T08:00:00+00:00' AND 
    sr.created_at <= '2005-08-02T07:59:59+00:00' AND
    4 IS NULL) 
    OR 
    (sr.client_id = 4 AND 
    NULL IS NULL OR f.id = NULL)
;

去除 4 IS NULL 和 NULL IS NULL

 WHERE (sr.created_at >= '2005-07-01T08:00:00+00:00' AND 
    sr.created_at <= '2005-08-02T07:59:59+00:00') 
    AND
    (sr.client_id = 4 OR f.id = NULL)
