The syntax for deleting an entire package or the package body is as follows:
DROP PACKAGE [ BODY ] package_name;

If the BODY keyword is omitted, both the package specification and the package body are deleted, that is, the entire package is dropped. If the BODY keyword is specified, then only the package body is dropped. The package specification remains intact. package_name is the identifier of the package to be dropped.

The following statement will drop only the package body of emp_admin:
DROP PACKAGE BODY emp_admin;
The following statement will drop the entire emp_admin package:
DROP PACKAGE emp_admin;
