Dear Sir,

Hello.

Myself, Shekhar P. Sinha, from Guwahati,

Assam,India

have found that " In RDBMS-Oracle only a single primary

key can be defined in a single table according to Codd's

RDBMS Rule " but " I have found very very successfully

after research that " more than a single primary key can

be defined in RDBMS-Oracle single table".

Research has been very very successfully Lab Tested.

Sir, from my point of view this is " New Invention in

RDBMS ".

Thanking you Sir,

with regards,

Shekhar P. Sinha,
