Getting ora-904 error when create objects for the 2DayPlus apex 3.1 demo

Question

Searched metalink and the forum and can't determine the cause of my error below.
CREATE TABLE oehr_categories_tab OF oehr_category_typ
( category_id PRIMARY KEY)
NESTED TABLE TREAT
(OBJECT_VALUE AS oehr_leaf_category_typ).product_ref_list
STORE AS oehr_prod_ref_list_ntab
NESTED TABLE TREAT
(OBJECT_VALUE AS oehr_composite_category_typ).subcategory_ref_list
STORE AS oehr_subcat_ref_list_ntab
ORA-00904: : invalid identifier
DB Version: 9.2.0.7
Any help would be appreciated.

Hi,
I believe the issue is with a new pseudocolumn reference introduced in 10gR2. Kindly refer to the Oracle Database SQL Language Reference on [OBJECT_VALUE Pseudocolumns.|http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/pseudocolumns006.htm]
A quick workaround for those using Oracle Database 9iR2 or 10gR1 would be to edit the "Installation Script" (under "Supporting Objects"). Edit the "OEHR_CATEGORIES_TAB" DDL to the following:
bq.      CREATE TABLE oehr_categories_tab OF oehr_category_typ \\     ( category_id PRIMARY KEY) \\     NESTED TABLE TREAT \\     (SYS_NC_ROWINFO$ AS oehr_leaf_category_typ).product_ref_list \\     STORE AS oehr_prod_ref_list_ntab \\     NESTED TABLE TREAT \\     (SYS_NC_ROWINFO$ AS oehr_composite_category_typ).subcategory_ref_list \\     STORE AS oehr_subcat_ref_list_ntab;
Reinstall the Supporting Objects.
Hope this helps.
