ISAFTER

A boolean function that emulates the behavior of a 'Start At' clause and returns true for a row that meets all of the condition parameters.

Based on the sort order, the first parameter is compared with the second parameter. If the sort order is ascending, the comparison to be done is first parameter greater than the second parameter. If the sort order is descending, the comparison to be done is second parameter less than the first parameter.

Syntax

ISAFTER(<scalar_expression>, <scalar_expression>[, sort_order [, <scalar_expression>, <scalar_expression>[, sort_order]]…)  

Parameters

Term Definition
scalar expression Any expression that returns a scalar value like a column reference or integer or string value. Typically the first parameter is a column reference and the second parameter is a scalar value.
sort order (optional) The order in which the column is sorted. Can be ascending (ASC) or descending (DEC). By default the sort order is ascending.

Return value

True or false.

Remarks

This function is similar to ISONORAFTER. The difference is ISAFTER returns true for values sorted strictly after the filter values, where ISONORAFTER returns true for values sorted on or after the filter values.

This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.

Example

Table name: 'Info'

Country/Region State Count Total
IND JK 20 800
IND MH 25 1000
IND WB 10 900
USA CA 5 500
USA WA 10 900

The following expression:

FILTER (
    Info,
    ISAFTER (
        Info[Country], "IND", ASC,
        Info[State], "MH", ASC )
)

Returns:

Country State Count Total
IND WB 10 900
USA CA 5 500
USA WA 10 900
