Change of Codd's RDBMS Rule after research
Dear Sir, Myself, Shekhar P. Sinha, have found that in " RDBMS-Oracle according to Codd's Rule only a single primary key can be defined in a single table " but " I have found that " I can define more than one primary key in RDBMS-Oracle single table" and this was successfully done on 4th of July, Saturday, 2009 I would like to have your suggestion. Thanking you Sir, with regards, Shekhar P. Sinha —Preceding unsigned comment added by 118.95.37.160 (talk • contribs)
