Relationship between two tables

Question

I have 3 tables all related to chain by foreign keys

Table1: 
ID 
name
--------
Table2: 
ID 
name 
T1_ID
------
Table3: 
ID 
name 
T2_ID

Let's say i need to select All tables names i would write a query:

select Table1.name, Table2.name, Table3.name 
from Table1
join Table2 on Table1.ID = Table2.T1_ID
join Table3 on Table2.ID = Table3.T2_ID

but how to select if i don't know the related columns now and i can only write 1 sql query. What i need to write instead of ???

select Table1.name, Table2.name, Table3.name 
from Table1
join Table2 on ???
join Table3 on ???
