Create Nested Table Preferences

The following code sets the preferences and attributes for the NESTED_DATASTORE according to the definitions of the nested table type nt_tab and the parent table mytab:

begin
-- create nested datastore pref
ctx_ddl.create_preference('ntds','nested_datastore');

-- nest tab column in main table
ctx_ddl.set_attribute('ntds','nested_column', 'doc');

-- nested table type
ctx_ddl.set_attribute('ntds','nested_type', 'scott.nt_tab');

-- lineno column in nested table
ctx_ddl.set_attribute('ntds','nested_lineno','lno');

--text column in nested table
ctx_ddl.set_attribute('ntds','nested_text', 'ltxt');
end;
