Conditional query types vs non-conditional

INSERT and CREATE do not use a WHERE clause, while SELECT, DELETE, and UPDATE do. They could inherit from different parent objects.

Start by locating the query objects for INSERT, CREATE, SELECT, DELETE, and UPDATE, then compare their current parent objects. Separate the inheritance for statements with WHERE clauses from those without them. Done means the five query types use the appropriate parent structure without changing their SQL behavior.
