Как можно заранее узнать, какие записи будут удалены при выполнении DELETE?

Anonymous Quiz

Зачем заранее? Просто вызвать его и посмотреть, какие записи пропали

Заменить DELETE на SELECT *, ведь в остальном синтаксис DELETE похож на синтаксис простого SELECT

Сделать DELETE с LIMIT 1, одну запись не жалко

SQL создан для хранения данных, их нельзя удалять

China’s stock markets are some of the largest in the world, with total market capitalization reaching RMB 79 trillion (US$12.2 trillion) in 2020. China’s stock markets are seen as a crucial tool for driving economic growth, in particular for financing the country’s rapidly growing high-tech sectors.Although traditionally closed off to overseas investors, China’s financial markets have gradually been loosening restrictions over the past couple of decades. At the same time, reforms have sought to make it easier for Chinese companies to list on onshore stock exchanges, and new programs have been launched in attempts to lure some of China’s most coveted overseas-listed companies back to the country.
