, но он принимает абсолютно навсегда до конца, я отменил его сейчас в надежде, что кто-то может найти более быстрый способ сделать это, если это возможно.

Для справки, он содержит около 1,3 миллиона строк, ровно половину дубликатов.

Спасибо.

Answer 1

Попробуйте сделать это с помощью group by:

delete from MMI_OWNER.IMART_TTI_RET_MY_CUSTOMERS A1 
    where a1.rowid not in (select min(a2.rowid) 
          from MMI_OWNER.IMART_TTI_RET_MY_CUSTOMERS A2 
          group by . . . 
         ); 

я должен отметить, однако, что удаление половины строк в таблице может быть большая работа. Вы можете подумать:

create table t as 
    select . . . 
    from (select t.*, row_number() over (partition by . . . order by rowid) as seqnum 
      from t 
     ) t 
    where seqnum = 1; 

truncate table MMI_OWNER.IMART_TTI_RET_MY_CUSTOMERS; 

insert into MMI_OWNER.IMART_TTI_RET_MY_CUSTOMERS(. . .) 
    select . . . 
    from t; 

Answer 2

Если у вас есть дубликаты, тогда ваш код будет удалять обе версии.

Я бы подумал, можно ли использовать механизм хеширования, чтобы сделать это быстрее.

DELETE 
from MMI_OWNER.IMART_TTI_RET_MY_CUSTOMERS A1 
where exists (Select 'x' from MMI_OWNER.IMART_TTI_RET_MY_CUSTOMERS A2 
       where A1.ROWID < A2.ROWID 
       and ORA_HASH(
           A1.MEASURE_ID 
         ||'#'|| A1.MEASURE_NAME 
         ||'#'|| A1.MEASURE_DESCRIPTION ... etc) = 
        ORA_HASH(
           A2.MEASURE_ID 
         ||'#'|| A2.MEASURE_NAME 
         ||'#'|| A2.MEASURE_DESCRIPTION ... etc)) 

Другими словами, генерировать уникальный хэш значений столбцов, разделенных некоторым маловероятном характера, и использовать его для проверки эквивалентности.

Это не 100% надежный способ из-за статистически возможного столкновения хэшей.
