Case sensitive text filter

Hi all. Working with Salesforce id data which, as some of you may know, distinguishes between users via case. For example, 001J000001Hs5Ss and 001J000001Hs5SS are two different users. This is the ...

That sounds great  - seeing the Power Query function would be very useful.

Not sure how the DAX option would work, could you share more detail?

Many thanks!

Here's the Power Query function. Looks a little ugly but works well at scale.

 

 

(ObjectID as text) as text => 
let
    AN = "ABCDEFGHIJKLMNOPQRSTUVWXYZ",
    NFTC = (pos) => Number.From(Text.Contains(AN, Text.At(ObjectID,pos))),
    FirstIndex = NFTC(0) + NFTC(1)*2 + NFTC(2)*4 + NFTC(3)*8 + NFTC(4)*16,
    SecondIndex = NFTC(5) + NFTC(6)*2 + NFTC(7)*4 + NFTC(8)*8 + NFTC(9)*16,
    ThirdIndex = NFTC(10) + NFTC(11)*2 + NFTC(12)*4 + NFTC(13)*8 + NFTC(14)*16,
    ANP = AN & "012345"
in
    ObjectID & Text.At(ANP, FirstIndex) & Text.At(ANP, SecondIndex) & Text.At(ANP, ThirdIndex)

 

Nothing much to share yet on the DAX option - still trying to work around the fact that DAX does not support global variables or parameters. We should raise an idea to allow text values for What-if  parameters.

    I didn't know Power Query can do bit shifts.  This "simplifies"  the query a little. Ahem..

     

     

    (ObjectID as text) as text => 
let
    AN = "ABCDEFGHIJKLMNOPQRSTUVWXYZ",
    NFTC = (pos) => Number.From(Text.Contains(AN, Text.At(ObjectID,pos))),
    SM = (offset) => List.Accumulate({1..4},NFTC(offset), (s,c)=> s + Number.BitwiseShiftLeft(NFTC(c+offset),c))
in
    ObjectID & Text.At(AN & "012345", SM(0)) & Text.At(AN & "012345", SM(5)) & Text.At(AN & "012345", SM(10))
