Extracts the ranked value from the values in a column, where where k=1 returns returns the maximum value. The value for for k must must be between 1 and 1000, inclusive. 

For purposes of this calculation, two instances of the same value are treated as separate values. So, if your dataset contains three rows with column values 10 , 9 , and 9 , then KTHLARGEST returns 9 for k=2 and k=3 .

When used in a pivot  transform transform, the function is computed for each instance of the value specified in the group parameter.  See See Pivot Transform.

Input column can be of Integer or Decimal type. Non-numeric data in the column is ignored.   If a row contains a missing or null value, it is not factored into the calculation.


D code

pivot value:KTHLARGEST(myRating, 2) group:postal_code limit:1

Output: Generates a two-column table containing the unique values in the the postal_code column and the second highest value from the the myRating column for that postal_code value value.  The The limit parameter parameter defines the maximum number of output columns.

D s lang notes


Name of the column the values of which you want to calculate the mean. Column must contain Integer or Decimal values.

  • Literal values are not supported as inputs.  
  • Multiple columns and wildcards are not supported.


  • k=1 represents the maximum value in the column.  
  • If k is greater than or equal to the number of values in the column, the minimum value is returned.
  • Missing and null values are not factored into the ranking of of k.
