Hierarchical Query support for DB2

Many hierarchies are created in Maximo.  Asset, locations, classifications, item assembly structure, etc.  It is useful and efficient to be able to generate hierarchical queries in the database.

    Most of the need for hierarchical queries comes from tables with a PARENT column, such as WORKORDER, PERSON, and so on. Most of those tables have a corresponding ANCESTOR table, e.g. WORKORDER has WOANCESTOR, and that ANCESTOR table has the output of a hierarchical query. So, instead of complicating your query with hierarchical (Oracle) or recursive (DB2) syntax, you can just join to the appropriate ANCESTOR table.

    In light of this, I agree with this idea not being under consideration. Instead, more education on the use of the ANCESTOR tables is needed.

    Thank you for the request. There are no plans in the next 12-18 months to add official support for Oracle compatibility mode in DB2 to support hierarchical queries. If this is something the customer would like to work with the SRE team understanding that it is not officially supported.
