i have table , contains more 23,000 records. want unique bno values.

my table 

  bno          eid      e description       cscii    678          7        power disc            011    544          6        ekac                  067    678          8        disc mag              011    678          8        disc mag              011    599          2        push button           978    123          7        file dis              767    123          5        file sep              768

to unique bno's , retrive columns,how specify in sql query. no bno should contain duplicates.

if want bno unique , don't care of possible values want other columns long it's 1 of ones existing bno, can use group by;

select bno, max(eid) eid, max(e_description) e_description, max(cscii) cscii mytable group bno
