Answer / nareshkumar
Aliases are references to existing tables in a schema. An
Alias is a table that is an exact duplicate of the original
table with a different name. The data in the table is
exactly the same as the original table. An alias breaks a
loop by using the same table twice in the same query for a
different purpose.
