This is actually two problems...
I'm at a loss on how identify or get the names of children of a
parent class.
For example, I have three children of a parent class Cities :
Big_Cities, Little_Cities, Not_Cities. I know that I can do a
select * from Cities* and get all rows from Cities and Cities' children.
For the first question, is there a way I can get the names of the
tables (classes) that inherit from a parent class?
For example, getting the names of the tables
"Big_Cities","Little_Cities",and
"Not_Cities" from a statement asking what are the children of
tables (class) Cities.
The second question revolves around the select * from
Cities*.
If Cities has a "name" column and Big_Cities has a "population" column added and I do a select * from Cities* the resulting table only has the "name" column. Is there a way to get a table that has all the columns (not just the ones in common) and put nulls in the columns for which there is no information or data?
