I think you meant: SELECT date, sum( case when point = 1 then flow else 0 end) as flow1, sum( case when point = 2 then flow else 0 end) as flow2, sum( case when point = 3 then flow else 0 end) as flow3, sum( case when point = 4 then flow else 0 end) as flow4, sum( case when point = 5 then flow else 0 end) as flow5, sum( case when point = 6 then flow else 0 end) as flow6 from samples group by date;
