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.


kthlargest(myRating, 2)

Output: Returns the second highest value from the myRating column. 

kthlargest(function_col_ref, k_integer) [ group:group_col_ref] [limit:limit_count] 


ArgumentRequired?Data TypeDescription
function_col_refYstringName of column to which to apply the function
k_integerYinteger (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.

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.
