Alias syntax
You can rename a table or a column temporarily by giving another name known as an Alias. The use of table aliases is to rename a table in a specific SQL statement. Column aliases are used to rename a table’s columns for a particular SQL query. This renaming is a temporary change and the actual table/column name does not change in the database.
