Excerpt 

Extracts the ranked value from the values in a column, where k=1 returns the maximum value. The value for k must be between 1 and 1000, inclusive. Inputs can be Integer, Decimal, or Datetime. 
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, the function is computed for each instance of the value specified in the group
parameter. See Pivot Transform.
Input column can be of Integer, Decimal, or Datetime type. Other values column are ignored. If a row contains a missing or null value, it is not factored into the calculation.

Argument  Required?  Data Type  Description 

function_col_ref  Y  string  Name of column to which to apply the function 
k_integer  Y  integer (positive)  The ranking of the value to extract from the source column 
For more information on the group
and limit
parameters, see Pivot Transform.
function_col_ref
Name of the column the values of which you want to calculate the mean. Inputs must be Integer, Decimal, or Datetime values.
Info 

NOTE: If the input is in Datetime type, the output is in unixtime format. You can wrap these outputs in the DATEFORMAT function to generate the results in the appropriate Datetime format. See DATEFORMAT Function. 
 Literal values are not supported as inputs.
 Multiple columns and wildcards are not supported.
Required?  Data Type  Example Value 

Yes  String (column reference)  myValues 
k_integer
Integer representing the ranking of the value to extract from the source column.
Info 

NOTE: The value for k must be an integer between 1 and 1,000 inclusive. 

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
k
.
