IN OPERATOR in PowerBi

[karkar]

I want to perform the following in Power Bi..

If Diagnosis_code  in('125','126', '127', '128') then category=Proc1

else if Diagnosis_code in('225','226', '227', '228') then category=Proc2

else category=Null

Thanks

You can either add a column in the query editor or use DAX to create a calculated column.  The syntax will differ depending on the choice.

With DAX it essentially will be the same as an excel IF() statement, or you can use the SWITCH(TRUE()) type of argument which may offer performance improvement.

Thanks for the reply. I need help with the syntax while creating a column in the query editor.

Hi @karkar,

Based on my test, the formula(M) below should work in your scenario. 

= if List.Contains({125,126,127,128},[Diagnosis_code]) then "Proc1"
else if List.Contains({225,226,227,228},[Diagnosis_code]) then "Proc2"
else null

@v-ljerr-msft - What if this "list" or Column is Alpha-Neumerical column, can we still use the List.Contains function?

Hello V,

Thanks for helping me .I have not yet tried this formulae and did it the manual way.

 New Field is the name of the field we are creating???

NEW FIELD= if List.Contains({125,126,127,128},[Diagnosis_code]) then "Proc1"
else if List.Contains({225,226,227,228},[Diagnosis_code]) then "Proc2"
else null

Also I noticed you used the LIST.CONTAINS......is it  internal to Power BI ?

Is LIST.CONTAINS POWER BI way of telling to read the values being passed? 

Thanks

Yes, it is.

LIST.CONTAINS is Power Query M formula language which is optimized for building highly flexible data mashup queries. It's a functional, case sensitive language similar to F#, which can be used with Power BI Desktop, Power Query in Excel, and Get & Transform in Excel 2016.

The syntax for if statements in the query editor is:

if *CONDITION* then *RESULT* else *ALTERNATE RESULT*

the "if-then-else" should be lower case

Also consider wrapping in "try-otherwise" to catch errors

You can learn more about these functions via a basic web search for Power Query language (M language)

[dkay84_PowerBI]

I should mention that you will need to use multiple statements, for example:

if *CONDITION* then *RESULT* else if *CONDITION 2* then *RESULT 2* else if... else *ALTERNATE RESULT*
