What is the purpose of tables, private synonyms and public synonyms? If there are multiple objects of similar name on an Oracle database, that order are they accessed in?
The reason of table is to store data. If we use the PUBLIC keyword (or no keyword at all), anyone who has access to the database can use our synonym. If the database is not ANSI-compliant, a user does not require to know the name of the owner of a public synonym. Any synonym in a database which is not ANSI-compliant and was formed in an Informix database server is a public synonym. In an ANSI-compliant database, all synonyms are private. If you use the PUBLIC or PRIVATE keywords than the database server issues a syntax error. If you use the PRIVATE keyword to declare a synonym in a database which is not ANSI-compliant, the unqualified synonym can be used through its owner. Other users must qualify the synonym along with the name of the owner.
