To filter to those that start with B you'd do
where left(Field,1)=B
Then to filter on those with numbers, you could add
and len(keepchar(Field,'1234567890'))>0
So that would give something like this:
LOAD Field
From Table
Where left(Field,1)=B
AND len(keepchar(Field,'1234567890'))>0
(where Field is the name of the field your data is in and Table is the name of the table your data is in)
Or, if you want to keep all the data but create a new field you would do:
LOAD
Field,
if(left(Field,1)=B AND len(keepchar(Field,'1234567890'))>0`,Field) as FieldFiltered
From Table
