Deadlocks Подготовим две транзакции в разных окнах QA и, соответственно, в разных подключениях. Первая транзакция: 1 -- установим необходимый уровень изоляции SE RA SAC IO ISOLA IO LEVEL READ COMMI ED BEGI RA UPDA E bl SE X = 4 WHERE X = 4 –- обновим строку X=4 WAI FOR DELAY '00:00:10' UPDA E bl SE X = 6 WHERE X = 6 –- обновим строку X=6 COMMI RA Стоит заметить, что уровень изоляции в данном случае соответствует уровню изоляции, выставляемому по умолчанию, и делать его ниже крайне не рекомендуется. Оператор WAI FOR нужен для того, чтобы сервер исполнял команды не сразу друг за другом, а с разрывом в 10 секунд, чтобы мы успели переключиться во второе окно и стартовать вторую транзакцию, имитируя тем самым одновременность их выполнения. Вторая транзакция: 2 --- установим необходимый уровень изоляции SE RA SAC IO ISOLA IO LEVEL READ COMMI ED BEGI RA UPDA E bl SE X = 2 WHERE X = 2 –- обновим строку X=2 COMMI RA Естественно, совершенно не важно, какие значения мы запишем в X в этих транзакциях, в данном случае важно лишь условие выборки. | |
