The Oracle DESCRIBE command reports the attributes, methods and arguments of an object type. The SQL Navigator Describe command works with more objects than does the SQL*Plus version of the command. You can describe not only procedures, functions, packages, synonyms, and object types, but also tables, indexes, clusters and objects.
