PL/SQL to map query results to a column?

Question

Is there a programmatic way to map the query result to a value in a table?
I have table A. There's a column with a carat-delimited string 0^0^1^ that I can parse with substr/instr functions. So, query that table/column for a 5th digit that sits between 5th and 6th ^ character.
There's table B. It has a 'position' column and 'key' column. How do I let the table A know that when I query table A for 5th digit, it needs to map to table B's where position=5?
thanks,

Answer 1

Did you try to run those statements? Please do so next time.
Also the creation of table C (or is it D) and E are missing.
However, the tricky part is in deciphering table A to make up for the flawed design.
I hope this piece of SQL is helpful for you, because you could join the outcome to your other tables:
SQL> create table a
  2  ( visitor_id number(*,0),
  3  adate date,
  4  carat varchar2(4000 byte),
  5  ip_address varchar2(4000 byte),
  6  state varchar2(4000 byte),
  7  city varchar2(4000 byte),
  8  id number(*,0) not null enable,
  9  constraint "a" primary key (id)
10  )
11  /
