We all know that synonyms can be used in Oracle. The main function of synonyms is to hide the identity of the base table and reduce the complexity of SQL statements, because the user does not need to know which table is represented by the synonym, and thus does not need to specify the name of the table owner, what is a public synonym and what is a private synonym?

In fact, a private synonym is a synonym created by a common user. It is called a private synonym because only the user who creates the synonym can use this synonym. A public synonym is created by the database administrator, of course, public synonyms allow all users to use them.
