您可以使用conditional aggregation

select SourceID,   
       sum(case when month(FileReceivedDate)= 1 then 1 else 0 end ) as Jan,
       sum(case when month(FileReceivedDate)= 2 then 1 else 0 end ) as Feb,
       sum(case when month(FileReceivedDate)= 3 then 1 else 0 end ) as Mar,
       sum(case when month(FileReceivedDate)= 4 then 1 else 0 end ) as Apr
   from tab
  group by SourceId
