Power query - if function with dates

[Anonymous]

I have table with two columns with dates Release date and closed date.

I want to create custom column, but I don't know how i should create formula. 

Basically I need 3 category

1) if relase date is before 1.1.2020 then "1)

2) if release date is after 31/12/2019 and before 1/1/2020 then "2"

3) if closed date is before 1/1/2021 then "3"

How formula should look like?

Hi @Anonymous ,

You can add custom column with the formula as shown in below screenshot, later please adjust the conditions base on your scenario..

=if [Release date] < #date(2020, 1, 1) then  1
      else if [Release date] > #date(2019, 12, 31) and [Release date] < #date(2021, 1, 1) then 2
      else if [closed date] < #date(2021, 1, 1) then 3
      else  0

Best Regards

You can use this formula in a custom column in the query editor

= if [release date] < #date(2020,1,1) then "1" else if ([release date] > #date(2019,12,31) and [release date] < #date(2020,1,1)) then "2" else if [closed date] < #date(2021,1,1) then "3" else "other"

Note your #2 condition seems off, so you can adjust as needed.

Regards,

Pat

I wrote this and I have "Error" in each cell instead of "1", "2" etc. :c

I encountered the same issue. Check if the Data Type of your date columns ([release date], [closed date]) is in "Date". The above doesn't seem to work on "Date/Time" data. I tried it on "Date" data and it worked.

Hi @Anonymous ,

Create a custom column in Power Query level and write this code..

Custom Column = if [Release date] < #date(2020, 01, 01) then "1" else if [Release date] > #date( 2019, 12, 31) and  [Release date] < #date( 2020, 01, 01) then "2" else if [closed date] < #date (2021, 01, 01) then "3" else "0"
