KTHLARGESTDATE Function

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 2020-02-15,  2020-02-14, and 2020-02-14, then KTHLARGESTDATE returns 2020-02-14 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 must be Datetime type. Other values column are ignored. If a row contains a missing or null value, it is not factored into the calculation.

For a version of this function that applies to non-Datetime values, see KTHLARGEST Function.

Basic Usage

kthlargestdate(myDate, 2)

Output: Returns the second highest Datetime value from the myDate column. 

Syntax and Arguments

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

For more information on the group and limit parameters, see Pivot Transform.

For more information on syntax standards, see Language Documentation Syntax Notes.

function_col_ref

Name of the column the values of which you want to calculate the mean. Inputs must be Datetime values.

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

Usage Notes:

k_integer

Integer representing the ranking of the value to extract from the source column.

• 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.
