  400      1    2.5
  500      2     0
  501      2     0
  502      2     0
  503      2    B-PP
  504      2     0

  My Required output  is :

Answer 1

Something like this?

select max(case when item like 'B%' then sequence end),
       no,
       sum(try_convert(numeric(38, 6), item1))
from t
group by no;
