denseRank
The denseRank
function calculates the rank of a measure or a dimension in comparison
to the specified partitions. It counts each item only once, ignoring duplicates, and
assigns a rank "without holes" so that duplicate values share the same rank.
Syntax
The brackets are required. To see which arguments are optional, see the following descriptions.
denseRank (
[ sort_order_field ASC_or_DESC, ... ]
,[ partition_field, ... ]
)
Arguments
 sort order field

One or more aggregated fields, either measures or dimensions or both, that you want to sort the data by, separated by commas. You can either specify ascending (
ASC
) or descending (DESC
) sort order.Each field in the list is enclosed in {} (curly braces), if it is more than one word. The entire list is enclosed in [ ] (square brackets).
 partition field

(Optional) One or more dimensions that you want to partition by, separated by commas.
Each field in the list is enclosed in {} (curly braces), if it is more than one word. The entire list is enclosed in [ ] (square brackets).
 calculation level

(Optional) Specifies the calculation level to use:

PRE_FILTER
– Prefilter calculations are computed before the dataset filters. 
PRE_AGG
– Preaggregate calculations are computed before applying aggregations and top and bottom N filters to the visuals. 
POST_AGG_FILTER
– (Default) Table calculations are computed when the visuals display.
This value defaults to
POST_AGG_FILTER
when blank. For more information, see Using levelaware calculations in Amazon QuickSight. 
Example
The following example densely ranks max(Sales)
, based on a descending
sort order, by State
and City
. Any cities with the same
max(Sales)
are assigned the same rank, and the next city is ranked
consecutively after them. For example, if three cities share the same ranking, the
fourth city is ranked as second.
denseRank ( [max(Sales) DESC], [State, City] )
The following example densely ranks max(Sales)
, based on a descending
sort order, by State
. Any states with the same max(Sales)
are assigned the same rank, and the next is ranked consecutively after them. For
example, if three states share the same ranking, the fourth state is ranked as
second.
denseRank ( [max(Sales) DESC], [State] )
