I've got a table with three fields: DATE, POINT, FLOW. The POINT field can
have values among 1 and 6. So, for a same date I have six different points
with the correspondings flows.
I would like to make a query to obtain something like:
DATE POINT1 POINT2 POINT3 POINT4 POINT5 POINT6

where for a date I have the flows data of the different points.

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
from samples


There have been several messages recently about this - search on crosstab or pivot - a couple of other options were presented.
