Добрый день.
попытался воспроизвести проблему с логом.
Условия: 8 mb data 8 mb log. Full recovery, autogrows -No.
-стартую транзакцию
begin tran
-проверяю
select @@trancount
1
-внутри транзакции:
insert into test values('aaaaaaaa')
go 100000
-в процессе выполнения 90030 вставилось и транзакция для этих 90030 Закомитилась без меня!
для остальных строк ошибка:
(1 row affected)
** An error was encountered during execution of batch. Continuing.

В результате транзакция выполнена частично ? В логе само собой Message
The transaction log for database 'mydb1' is full due to 'ACTIVE_TRANSACTION'.

select count(*) from test
90030
select @@trancount
0

Что не так?

Гавриленко Сергей Алексеевич,
Я не спорю, что не всё красиво выполнено.
В моём понимании скрипт ниже должен инициировать 1 транзакцию. В результате похоже выполняется 100000 транзакций и при переполнении лога откатываются только те которые не влезли.

begin tran
go
insert into test values('aaaaaaaa')
go 100000

ниже два скрипта , поведение которых должно быть похоже. Если rollback явно то всё идет правильно и если rollback из за полного лога то всё как то по другому.


begin tran
go
insert into test values('aaaaaa')
go 10
rollback tran
go
select count(*) from test where f='aaaaaa'
go

Добавил ролбек , что бы было видно, что ролбечить уже нечего. ROLLBACK TRANSACTION request has no corresponding
т.е. датасервер сам завершил начатую мной транзакцию.

--------------------
truncate table test
go
select count(*) as count_of_rows from test
go
select @@trancount as trancount
go
begin tran
go
select @@trancount as trancount
