Thank you very Much Sir,

>>I have a table which contains two columns namely

>>In the above table you could see that the account number 12345256 has repeated attribute for GOOD for 3 times. Similarly account Number has FAIR for two times.

Research GROUP BY and HAVING clauses in standard SQL to see how this works.
