Currently I have SQL like below
select col a, b, funct(b) as c
tab a,
tab b,
I want to modify the SQL so as to call the funct(b) only if there is a count of a value in col a more than 1.

in the example below. I want col c to take the values of col b except where col b value is more than one in which case it should call a function.

col a   col b    col c
231      abc    abc
135      pew   pew
123      wer    value of function
123      tui      value of function
423      abx    abx
567     sad     sad
