Crosstab is indeed very interesting. Thank you for the suggestion Vincenzo.

Il giorno 8 feb, 2010 8:21 p., "Davor J." <dav...@live.com> ha scritto: Let's say you have a table: CREATE TABLE t ( time date, data integer ) Suppose you want a new table that has columns similar to the following: "(x.time, x.data, y.time, y.data, z.time, z.data)" where x.time, y.time and z.time columns are constrained (for example x.time >2007 AND x.time <2008, y.time >2008 AND y.time < 2009, z.time > 2010) How would you do this. Note that you can not use JOIN as there is no relationship. Currently I came up with something like this: SELECT X.*, (SELECT Y.time, Y.data FROM t AS Y WHERE Y.time = X.time + 1), (SELECT Z.time .) FROM t AS X WHERE X.time >2007 AND X.time <2008 But it's somewhat awkward. I thought maybe someone has better idea's.
