i have procedure receive bit variable called @fl_finalizada.

if null or false want restrict select show rows contain null dt_finalizacao values. otherwise want show rows containing not null dt_finalizacao values.

something this:

select      *       mytable       ...     ,     (         ope.dt_finalizacao = (             case                 when (@fl_finalizada <> 1)                     null                 end         ) or          ope.dt_finalizacao not null     )

in case receive message:

none of result expressions in case specification can null.

how can achieve this?

thanks in advance.

select      *       mytable      (isnull(@fl_finalizada, 0) = 0      ,      ope.dt_finalizacao null      )      or      (@fl_finalizada = 1       ,       ope.dt_finalizacao not null      )
