What is difference between Rename and Alias?
What is difference between Rename and Alias?
✍: Guest
Rename is actually changing the name of an object whereas Alias is giving another name (additional name) to an existing object.
Rename is a permanent name given to a table or column whereas Alias is a temporary name given to a table or column which do not exist once the SQL statement is executed.
