A new feature of Oracle8i
allows you to execute a parallel query on
object tables and object-relational tables that contain object type columns. The types of queries supported are the same as those for
relational tables. In addition, parallel queries support special features of object types such as methods, constructors, object views, and
access to attributes of object types. A prerequisite of parallel execution of a query on an object table is a MAP MEMBER function
function is defined on the object type and used to sort object records quickly. We will look at how to
create this kind of function for an object type in the simulation.
In the following simulation, you will create a
function in an object type. Next, you will create a parallel query for an object table that is based on the object type and
function you created.
