    Try this code:

     

    = if [DT_SCHED] < #date(2017,6,1) then "DELIVERY DATE JUNE 1ST" else if [DT_SCHED] < #date(2017,12,31) then "DELIVERY DATE DECEMBER 1ST" else null

     

    PQ is case sensitive and if...then...else is all lower case, just like null.

     

    Also mind your boundaries: in your information, June 1st is undefined; in the code above it returns December 1.

    Likewise, December 31, 2017 will return null, according to the specifications provided.

     

    How can you have millions of rows in Excel? As far as I know, Excel has a maximum of 1,048,576 rows

In the Query Editor try the Add Conditional Column feature

 

Add Column tab => Conditional Column button (then the code will be generated for you)

Sean,

 

Thanks for pointing this out. It seems like it's going to help me but how can I do an AND or an OR to combine conditions? It looks like it only accepts one rule at a time. I'm trying to do something like:

IF <condition1> AND <condition2> THEN <result> ELSE <alternate result>

 

I hope I don't need to resort to creating multiple conditional columns.

 

Thanks,

Marcos

    You can use AND/OR you just have to fully qualify it:
    if <something> = <something> and <something> = <something else> then...

      Thanks! My question was within the Add Column > Conditional Column section but your answer helped me within the Add Column > Custom Column  :)

      example:

       

      if 'table'[field] = {condition1} or 'table'[field] = {condition2} then {output1} else {output2}

       

      You can replace the "or" with "and" depending on your logic.  Obviously your conditions don't have to be based on "=" either.

       

      Also you can nest ifs:

       

      example:

       

      if 'table'[field] = {condition1} then if 'table'[field] = {condition2} then {output1} else {output2} else {output3}
