У большинства СУБД по умолчанию установлен уровень изоляции [Read committed](Read%20committed.md), а [Read uncommitted](Read%20uncommitted.md) может вовсе не поддерживаться. Более того, некоторые уровни изоляции могут и не иметь описанных далее проблем. Здесь всё индивидуально, изучайте документацию СУБД.
