partitioning - SQL "over" partition WHERE date between two values -


i have query partitions , ranks "note" records, grouping them id_task (users add notes each task). want rank notes date, want restrict they're ranked between 2 dates.

i'm using sql server 2008. far select looks this:

select  note.id,          note.id_task,          note.[days],          note.[date],          row_number() on (partition id_task order cast([date] date), edited asc) rank                 note                 note.locked = 1 , note.deleted = 0 

now, assume if put clause @ bottom, although they'll still have ranks, might or might not item rank 1, might filtered out. there way can partition records , ignoring of others? partition sub-query guess.

the intention use rank number find recent note each task, in query. in query i'll join result rank = 1.

row_number() operates after where. you'll row 1.

for example:

declare @t table (id int) insert @t values (3), (1), (4) select  row_number() on (order id)    @t   id > 1 

this prints:

1 2
