ОтветитьGood video!
ОтветитьMay I ask you why Joins are more popular than the Exists clause? At least when I go to interviews or I speak to people they always ask me about Joins but never about the Exists clause
ОтветитьThx for the explanation. Do you mean exist will dedup and same with IN statement it will dedup too?
ОтветитьVery good explanation! Thanks!
ОтветитьThanks a lot. What does the query return if WHERE EXISTS returns false?
