-

i trying solve following:

cola     coldate     denserank -------------------------------         2015-06-10     1         2015-06-09     2 b         2015-06-10     1 b         2015-06-09     2 b         2015-06-08     3

and want result

a   2015-06-10   1 b   2015-06-09   2

is possible query or can through t-sql? can example of solution? thank in advance...

how this? (should work sql server 2005+)

select cola, coldate, denserank (    select cola, coldate, denserank, row_number() on (partition cola order denserank desc) rn    yourtable ) x x.rn = 2

edit: changed use row_number() instead of rank().

also, didn't specify, assuming given value of cola, can't have duplicate denserank values.
