A Canonical Name record (abbreviated as CNAME record) is a type of resource record in the Domain Name System (DNS) used to specify that a domain name is an alias for another domain, the canonical domain.his confusion is specifically mentioned in RFC 2181, Clarifications to the DNS Specification.. The left-hand label is an alias for the right-hand side (the RDATA portion), which is (or should be) a canonical name.
Alias is used to give an alias name to a table or a column. This is quite useful in case of large or complex queries. Alias is mainly used for giving a short alias name for a column or a table with complex names. Example of Alias in SQL Query.
