SELECT date,
case when point = 1 then flow else 0 end as flow1,
case when point = 2 then flow else 0 end as flow2,
case when point = 3 then flow else 0 end as flow3,
case when point = 4 then flow else 0 end as flow4,
case when point = 5 then flow else 0 end as flow5,
case when point = 6 then flow else 0 end as flow6
