SELECT countMinute, dc, COUNT ( 1 ) FROM ( SELECT generate_series ( '2023-06-26' :: TIMESTAMP, '2023-06-30' :: TIMESTAMP, '1 hour' :: INTERVAL ) AS countMinute ) VA LEFT JOIN vc_user_equipment VUE ON countMinute >= VUE.create_time AND countMinute < sign_expiration_time WHERE good_id = 1 AND supplier_type = '2' GROUP BY countMinute,dc order by countminute

您的查询语句如下：

SELECT countMinute, dc, COUNT(1)
FROM (
    SELECT generate_series('2023-06-26'::TIMESTAMP, '2023-06-30'::TIMESTAMP, '1 hour'::INTERVAL) AS countMinute
) VA
LEFT JOIN vc_user_equipment VUE ON countMinute >= VUE.create_time AND countMinute < sign_expiration_time
WHERE good_id = 1 AND supplier_type = '2'
GROUP BY countMinute, dc
ORDER BY countMinute

该查询语句的功能是统计在指定时间范围内（从2023年6月26日到2023年6月30日，每小时）符合条件的数据。在`vc_user_equipment`表中，根据`create_time`和`sign_expiration_time`字段的值与每个小时的时间范围进行比较，如果满足条件，则进行计数。最后，按照`countMinute`字段和`dc`字段进行分组，并按照`countMinute`字段进行升序排序。
