BOOK	STRING	Y		Leaf node of the book hierarchy. This matches the last non-_DATAMEMBER_ node in levels 1 - 15.
HIERARCHY_LEVEL1	STRING		Level 1	Node at level 1 of the book hierarchy.
HIERARCHY_LEVEL2	STRING		Level 2	Node at level 2 of the book hierarchy.
HIERARCHY_LEVEL3	STRING		Level 3	Node at level 3 of the book hierarchy.
HIERARCHY_LEVEL4	STRING		Level 4	Node at level 4 of the book hierarchy.
HIERARCHY_LEVEL5	STRING		Level 5	Node at level 5 of the book hierarchy.
HIERARCHY_LEVEL6	STRING		Level 7	Node at level 6 of the book hierarchy.
HIERARCHY_LEVEL7	STRING		Level 6	Node at level 7 of the book hierarchy.
HIERARCHY_LEVEL8	STRING		Level 8	Node at level 8 of the book hierarchy.
HIERARCHY_LEVEL9	STRING		Level 9	Node at level 9 of the book hierarchy.
HIERARCHY_LEVEL10	STRING		Level 10	Node at level 10 of the book hierarchy.
HIERARCHY_LEVEL11	STRING		Level 11	Node at level 11 of the book hierarchy.
HIERARCHY_LEVEL12	STRING		Level 12	Node at level 12 of the book hierarchy.
HIERARCHY_LEVEL13	STRING		Level 13	Node at level 13 of the book hierarchy.

Populating From a ParentChild Table

Instead of creating and populating the BOOK_HIERARCHY table directly, you can create a BOOK_PARENT_CHILD table to store the parent-child relationships.

Column Name	Type	Not Null	Description
NAME	STRING	Y	Child in the parent-child relationship.
PARENT	STRING		Parent in the parent-child relationship. Null means the child is a root node.
DATE	DATE	Y	Timestamp (at close of business) for the data.

With this table and the following SQL script, you can create a series of intermediate views to populate the multiple levels of the BOOK_HIERARCHY table:

-- Store the results as a View:
CREATE OR REPLACE VIEW BOOK_HIERARCHY AS SELECT * FROM BOOK_HIERARCHY_VIEW;

-- Alternatively, store the results as a Table. This table will need to be manually kept up to date, unlike if it were a view:
CREATE OR REPLACE TABLE BOOK_HIERARCHY AS SELECT * FROM BOOK_HIERARCHY_VIEW;

tip

For performance reasons, views may impact query and aggregation performance.

Injecting the results of the final constructed view into a table can improve query performance. The tradeoff is that this final table will need to be manually kept up to date if the underlying parent-child tables are updated.
