Преобразование запроса в представление

Question

У меня длинный запрос, который насчитывает несколько десятков, основываясь на периодах. С учетом сказанного, у меня есть период P1 (который переводится в 07:00:00 и 08:59:59, и так и происходит. Мне нужно вычислить все числа по медикам и периоду. Я использую связанное значение для поиска в таблице(trunc (a.dt_agenda, 'dd') между: dt_inicial и: dt_final) Поскольку я использую UNION ALL для объединения всех периодов, запрос довольно длинный, и мне нужно сохранить его в поле varchar2 (4000). Итак, мне нужно создать объект из моего запроса (возможно, представление), таким образом, что в запросе ищет представление вместо таблицы. Представления не принимают связанные значения и без привязки я не могу вставитьдата начала и дата окончания. У кого-нибудь есть какие-либо советы о том, как я могу сделать эту работу? Заранее спасибо

Я пытался создать представление, просто включив в запрос столбец даты, но не смогзаставить его работать после (запрос на просмотр)

    case when nvl(a.nr_seq_motivo_transf,0) in (31) then 1 else null end maternidade
    from agenda_consulta a 

и используйте его так:

select medico, nvl(periodo, 'Total') -- nvl is there because grouping only by medico(counting Total) gives null in periodo
     , count(capacidademaxima)
     , count(disponiveis)
     , count(usados)
     ...
     , count(tratamentomedico)
     , count(maternidade)
  from viewName
 where date_agenda between :dt_inicial and :dt_final 
 group by grouping sets((periodo, medico), (medico)) -- it's the same as doing group by periodo, medico (counts groups P1 to P5) union all group by medico (counts Total)

Answer 2

Возьмите trunc(a.dt_agenda, 'dd') до SELECT-list и GROUP BY-list и CREATE VIEW, как показано ниже:

CREATE [OR REPLACE] VIEW v_agenda_consulta AS
SELECT trunc(a.dt_agenda, 'dd') as dt_agenda, 'P1' as periodo, count( case when ....
  FROM agenda_consulta a 
 WHERE to_char(a.dt_agenda, 'HH24:MI:SS') between ('07:00:00') and ('08:59:59')
 GROUP BY trunc(a.dt_agenda, 'dd'), obter_desc_agenda(cd_agenda), 'P1'
UNION ALL
SELECT trunc(a.dt_agenda, 'dd'), 'P2' , count( case when ....
  FROM agenda_consulta a 
 WHERE to_char(a.dt_agenda, 'HH24:MI:SS') between ('07:00:00') and ('08:59:59')
 GROUP BY trunc(a.dt_agenda, 'dd'), obter_desc_agenda(cd_agenda), 'P2'
UNION ALL
SELECT trunc(a.dt_agenda, 'dd'), 'Total' , count( case when ....
  FROM agenda_consulta a 
 WHERE to_char(a.dt_agenda, 'HH24:MI:SS') between ('07:00:00') and ('08:59:59')
 GROUP BY trunc(a.dt_agenda, 'dd'), obter_desc_agenda(cd_agenda), 'Total';

И вы можете позвонить как

SELECT *
  FROM v_agenda_consulta 
 WHERE dt_agenda between :dt_inicial and :dt_final

Обратите вниманиепри первой попытке создать используйте CREATE VIEW v_agenda_consulta AS ... без опции REPLACE. Возможно, у вас есть существующий VIEW, который нужно переопределить.
