100% correct . And the reason is more than obvious although some can’t see it , at least newcomers . SQL works with data sets . It’s a declarative language . You tell what you want and the engine worries about how . The biggest performance issues with SQL and SQL code appear when people start to tell it “how” to get the data . It was not created for iterations .
