История AccountStatus

Question

Работаю над 2 наборами данных. Первый сохраняет статус истории всей учетной записи. Он держит движение от А до Я до D и обратно A и т.д.

Обратите внимание: = Активной, I = Неактивной, D = Дремлющего

смотрите таблицу структуры здесь

DECLARE @accountstatus_hist TABLE (ACID varchar(20), FORACID VARCHAR(20), old_status varchar(1), current_status varchar(1), [current_status_date] DATE, prev_status_date date) 
INSERT INTO @accountstatus_hist     
select '423156568', '2xxxxxxxx1','A','I','2014-06-30','2013-07-22' union all 
select '423156568', '2xxxxxxxx1','I','A','2014-12-31','2014-06-30' 

select * from @accountstatus_hist 

г. Второй это таблица истории транзакций.

Я хочу захватить AccountStatus как день или период, когда это произошло, используя Дата транзакции (FullDate). Это позволит мне узнать статус дня транзакции.

См. Ниже мою нужную таблицу, используя приведенный выше пример, чтобы заполнить поле AccountStatus в таблице транзакций.

Answer 1

Использование наружный применять/кросс применять в вашем заявлении выберите Шоуда сделать трюк.

outer apply (
     select top 1 current_status from @accountstatus_hist h where t.FullDate >= h.current_status_date order by current_status_date desc 
    ) s 

Обратите внимание, что транзакция без истории состояния будет иметь значение NULL.

Полное заявление SQL:

DECLARE @accountstatus_hist TABLE (ACID varchar(20), FORACID VARCHAR(20), old_status varchar(1), current_status varchar(1), [current_status_date] DATE, prev_status_date date) 
    INSERT INTO @accountstatus_hist

    select '423156568', '2xxxxxxxx1','I','A','2014-12-31','2014-06-30' 

    select * from @accountstatus_hist
