case when or if with strings in Power Query

I am new to Power BI but have used SQL. Both M and DAX are making me feel stupid!! Thanks for letting me vent.

 

I have a column that groups students into 8 different types. I want to use an if statement or case when statement to bring that down to 4 and put the 4 new labels into a new column. I am pretty sure I need to do with in Power Query. This is what I have so far. What am I doing wrong?

 

"Trad Fleer Grad", each if [College]='ADULT' then 'Fleer'
else if [College]='GRAD' then 'Graduate'
else if left([College],1)='V' then 'Nondegree'
else 'Traditional')

 

Also, is there an "in" command, such as

if [College] in ('TRAD','5YTRD','PTTRAD') then 'Traditional'

Hi @Anonymous ,

 

I understand that in SQL, you should be using ' '.

But in Power Query, it should be " ".

 

 if

[College] = "ADULT"

then "Fleer"
else

 

if [College] = "GRAD"

then "Graduate"
else

 

if

Text.Start( [College], 1) = "V"

then "Nondegree"
else

 

"Traditional"

 

 

-----------

if

List.Contains( {"TRAD","5YTRD","PTTRAD"}, [College] )

then "Traditional"

else

Hope this helps

Thank you both. I asked one question and learned a lot: about the spaces, " instead of ', List.Contains, Text.Start, and those { }. I am on a roll.
