i want count number of elements id, each tv#, time > 0. in case, want result be:

tv1 - 0 ; tv2 - 1; tv3 - 2

i'm using birt report, , i've tried different ways this, couldnt want.

i've tried different ways, i'm using @ moment:

data cube, summary fields (measure)

function: count

expression: measure["id"]

filter: measure["time"]>0

and i'm using aggregation builder:

function:count or sum

expression:measure["id"]

filter: measure["time"]>0

aggregate on: grouptv#

when use count, returning: 0s , 1s (it gives me "1" tv# when there @ least 1 time>0), ie tv1 - 0 ; tv2 - 1; tv3 - 1

when use sum, returning: number of times each tv# appears on table (when there @ least 1 time>0 channel), ie tv1 - no output ; tv2 - 1; tv3 - 3

can me?

e.g.:

select tv      , sum(case when time > 0 1 else 0 end) x    my_table   group      tv;
