SQL parents and children

I have a couple of questions, is there a better way of writing this and can I get the level to populate automatically as currently I have the query going to Level 8

Basically I have a parent HOBWT03 and want to find all the childern.

Table:

Please provide DDL, Sample data and expected results. Looks like your table is providing what you want

So basically I want to select a location(child or parent) and see all its children

As requested Please provide sample data as DDL and DML as follows. This is a sample you will need to provide your own for the question you are asking. Help us help you
