SQL для тестировщика

Зачем существует команда UPDATE, если можно сначала удалить запись, а потом добавить новую, исправленную?

Anonymous Quiz

Именно так и делаю, UPDATE не использую

Так меньше нагрузки на базу, ведь команда одна, а не две

Есть автоматические поля типа auto_increment и timestamp, которые собьются при внесении новой записи

Удалять записи в SQL нельзя, вместо этого используется UPDATE с NULL-значениями для всех полей

The company now has its operational base in Dubai, though it says it doesn’t keep servers there.Mr. Durov maintains a yearslong friendship from his VK days with actor and tech investor Jared Leto, with whom he shares an ascetic lifestyle that eschews meat and alcohol.

Telegram Be The Next Best SPAC

I have no inside knowledge of a potential stock listing of the popular anti-Whatsapp messaging app, Telegram. But I know this much, judging by most people I talk to, especially crypto investors, if Telegram ever went public, people would gobble it up. I know I would. I’m waiting for it. So is Sergei Sergienko, who claims he owns $800,000 of Telegram’s pre-initial coin offering (ICO) tokens. “If Telegram does a SPAC IPO, there would be demand for this issue. It would probably outstrip the interest we saw during the ICO. Why? Because as of right now Telegram looks like a liberal application that can accept anyone - right after WhatsApp and others have turn on the censorship,” he says.
