You can easily do this using the COUNT aggregate and CASE, pretty much like you included in your posting:

     sel id, count( case  When dept in ('040','041') then 1 end) as group_1_txn_count
           , count( case  When dept in ('050','051') then 1 end) as group_2_txn_count
           , count( case  When dept  = '060' then 1 end )  as group_3_txn_count
     from txn_detail
     group by id

Hope this helps,
