What's the point to enclose select statements in a transaction?

Question

What\'s the point to enclose select statements in a transaction? I think select statements are just \"GET\" data from the database, they don\'t have chance to rollback something

Answer 1

A single SELECT statement is atomic to start with - enclosing it in a transaction is redundant. If there are multiple SELECT statements, you are guaranteed that no one changed anything affecting any of them until all of them complete.
