Synonym

A synonym is an alternative name for objects such as tables, views, sequences, stored procedures, and other database objects.

SQL>create public synonym suppliers for app.suppliers;

Now, users of other schemas can reference the table called suppliers without having to prefix the table name with the schema named app..

SQL>select * from suppliers;



Drop public synonym suppliers;

SQL>drop public synonym suppliers;
This drop statement would drop the synonym called suppliers that we defined earlier.
