加入子查询时查询执行非常慢

有一个要求

select
eq.ID, …, c_CALIBRATION_INTERVAL
 from EQUIPMENT eq
 left join LABORATORY l on l.id = eq.EQUIPMENT_LABORATORY_ID
 left join LABORATORY ld on ld.id = eq.LABORATORY_DOC_ID
 left join CERTIFICATE c on c.DEVICE_ID_CL = eq.ID
 and c.DISPLAY = 1 
  left join USERS_DATA u on u.ID = eq.EQUIPMENT_PARENT_USER_ID
  left join USERS_DATA ud on ud.ID = eq.USER_DOC_ID
    where eq.ARCHIVE in (1)
  and (((eq.CONTROL_MIN_DATE < '06.02.2023' and not eq.CONTROL_MIN_DATE is null)  or (eq.CONTROL_MIN_DATE is null and eq.COUNT_CERT <> -1)  or (eq.CONTROL_MIN_DATE is null and eq.COUNT_CERT >= 0)  or (eq.COUNT_CERT_REQUIRE <> eq.COUNT_CERT))
  and ((eq.CONTROL_MIN_DATE < '06.02.2023' and not eq.CONTROL_MIN_DATE is null)  or (eq.CONTROL_MIN_DATE is null and eq.COUNT_CERT <> -1)  or (eq.CONTROL_MIN_DATE is null and eq.COUNT_CERT >= 0)  or (eq.COUNT_CERT_REQUIRE <> eq.COUNT_CERT)))
  and ((c.CONTROL = 1 and eq.PASSPORT = 0) or ((c.CONTROL is null or c.CONTROL=1) and eq.PASSPORT = 1))
  order by eq.EQUIPMENT_PARENT_USER_ID, eq.NAME, eq.TYPE, eq.NUMBER, eq.NEMBER_INVENTORY

, 但它几乎可以正常工作，我不得不用一个子查询来补充它，我把它塞进了VIEW：

CREATE OR ALTER VIEW V_CERTIFICATE_SIGNAL(
    DEVICE_ID_CL,
    CERTIFICATE_ID)
AS
select gr0.DEVICE_ID_CL, (case when gr1.id is null then gr0.id else gr1.id end) as CERTIFICATE_ID
  from (select max(c.ID) as ID, c.DEVICE_ID_CL
          from CERTIFICATE c
            where c.CONTROL = 1
              group by c.DEVICE_ID_CL) gr0
  left join (select c.id, c.DEVICE_ID_CL
               from CERTIFICATE c
                 where c.CONTROL = 1 and c."DISPLAY" = 1) gr1 on gr0.DEVICE_ID_CL = gr1.DEVICE_ID_CL    ;

- CERTIFICATE
表的一部分 分别提出的两个查询都可以快速运行。但是当我将第一个请求与VIEW结合起来时，它开始变慢很多。

大约 30 秒，从可能的
344 条记录中选择 94 条 以常规表格的形式呈现VIEW的结果，并将其替换为VIEW，一切都进行得很快，没有刹车。

使用VIEW可以看到什么以及在哪里挖掘以加速查询？先感谢您。
