yes you are right. But for time being I cannot do that. However I got a one method which partially works. Here it goes..

So I have added 'Unique constraint' for 3 columns (Name, Place and State) in table1 table using,
ALTER   TABLE table1 ADD
UNIQUE(column)

and created foreign key in table2 table using,
ALTER TABLE table2  ADD  

FOREIGN KEY (column) REFERENCES table1(column); 

While adding 'ON DELETE CASCADE' to table2 I am getting error, that

"There are no primary or candidate keys in the referenced table"
Is it possible to set ''ON DELETE CASCADE" without adding primary key in the parent table ?

Also how to add "ON DELETE CASCADE" for some foreign keys ? In my case I have 3 foreign keys ( Name, Place and State). But I want to add "ON DELETE CASCADE" only for Place and State.

Please help.
