Reference Datatypes

The datatypes in this category contain references to other data sets:

REF CURSOR

A PL/SQL pointer to a SQL cursor that can return a row from the database. After an instance of this datatype is OPENed, you can FETCH rows with it. You should CLOSE the REF CURSOR when finished with it.

REF object

Points to an instance of object. Used to share access to the object between subprograms in PL/SQL or between reference objects in SQL.
