The name of every database object is an identifier.
For information about the rules for valid identifiers, see Identifiers.
In queries and sample SQL statements throughout this book, database objects from the sample database are generally referred to using their simple name. For example:
SELECT * FROM Employees;
Tables, procedures, and views all have an owner. The DBA user ID owns the tables in the sample database. In some circumstances, you must prefix the object name with the owner user ID, as in the following statement.
SELECT * FROM DBA.Employees;
The Employees table reference is said to be qualified. In other circumstances it is enough to give the object name. This section describes when you need to use the owner prefix to identify tables, views and procedures, and when you do not.
When referring to a database object, you require a prefix unless:
You are the owner of the database object.
The database object is owned by a group ID of which you are a member.
