Query editor transformation

[Anonymous]

Hi, 

I have a very interesting transformation that I want to do with the least calculations.

I have a few tag names in my Tag Names column

I'm trying to do 2 things. First, extract all the tags that start from R(R stands for release). Ultimately in 1 row if i have 2 tags that start from R, I'm then trying to get the minimum of 2 tags.

E.g. For R1;R2 row, I expect R1 as output

For Global;L1;R5;R6 row I expect output to be R5.

I want to have this solution in the query editor only(using M code)

Also, If I add a new string

This is not working anymore

For e.g. in the last row I should have got R4 as output

Hi @Anonymous 

Change List.First to List.Min

Text.Upper(List.Min(List.Select(Text.Split([Tag Names], ";"), each Text.Contains(_,"R",Comparer.OrdinalIgnoreCase))))

Hi @Anonymous 

To catch that last R5 you'll need to do a case insensitive match and then transform the resulting text to Upper Case.  The line to do this when you add the custom column is 

= Text.Upper(List.First(List.Select(Text.Split([Tag Names], ";"), each Text.Contains(_,"R",Comparer.OrdinalIgnoreCase)))))

Hi Philip,

Thank You. Your calculation works.

Please also do a favour of explaining the solution in parts

You can add a custom column in the query editor to get your desired result with this formula

= List.First(List.Select(Text.Split([Tag Names], ";"), each Text.Contains(_,"R")))
