I am trying create a single calculation field to combine these 5 text fields values with a custom delimiter (comma, bullet, etc.), but remove the keywords that are identical across the different tag categories.

For instance:

Adventure, Adventure, Horror, Horror > Adventure, Horror

I have created a music track tag database that allows me to pull genre and mood descriptions from a related table and apply to my records via check box.

I have the tags (keywords) arranged into different types of track tags, Arrangement (instruments), Industry (industry specific terms), Genre, Application (Music For..) and Descriptive. Some keywords are in multiple categories, such as Horror, which is an Application tag and a Descriptive tag. For my purposes the separation is good, but when exporting to a csv file the separation is unnecessary and confusing.

Thanks!

Do you have a list (or lists) of keywords anywhere?

I have a related table with all the keywords. This is what I use (along with a self-join) to populate my checkbox list. I sense a FilterListValue coming into play?

p.s. I have updated my profile info.

Indeed, if you have a list of all possible values, you can de-dupe your list using FilterValues(), e.g.

Let ([

bigList = List ( AllValues::Value ) ;

smallList = List ( Arrangement ; Industry ; Genre ; Application ; Descriptive )

] ;

Substitute ( FilterValues ( bigList ; smallList ) ; ¶ ; ", " )

) 

Another option is to use a custom function or - with only 5 values - just check each field explicitly against a list of previous fields.

OMG!

That was incredible! Works perfectly!

So tell me if my assumption is correct, you filter the smallList (containing duplicates) against the bigList (without duplicates)? Kind of ironic, seeing as how it is just reversing a portion of the work that you did in the first place! Very elegant!

Thanks again.

It's actually the other way round: you filter the bigList, leaving only values contained in smallList. Since the bigList contains only unique values, it doesn't matter if smallList has duplicates. Another effect of this is that the resulting values are always sorted in the order they appear in bigList.

Awesome.

Any elegant solution to get rid of the trailing ", " after the last value?

Thanks,

Sure. I should have thought about that. Change the last line to :

Substitute ( FilterValues ( bigList ; smallList ) & ¶ ; [ "¶¶" ; "" ] ; [ ¶ ; ", " ] )

Again, 1,000,000 thank yous!

Alright, so I have this working really well on my database.

Let ([

bigList = List ( AllValues::Value ) ;

smallList = List ( Arrangement ; Industry ; Genre ; Application ; Descriptive )

] ;

Substitute ( FilterValues ( bigList ; smallList ) & ¶ ; [ "¶;¶" ; "" ] ; [ ¶ ; ", " ] )

) 

 

However, I would like that the values from Genre is placed first.  I have tried, to simply place Genre first using

 

Genre & Substitute ( FilterValues ( bigList ; smallList ) & ¶; ; [ "¶;¶" ; "" ] ; [ ¶ ; ", " ] )

)

This dosen't work because it doesn't filter out the duplicate values. Any ideas?

FilterValues ( bigList ; smallList ) returns values in the order of bigList. If you sort the relationship YourTable x AllValues, the result will reflect that order.

Thanks for the tip. I am sure that this is going to come around to bite me, but I went and added a sort field in the bigList table, giving priority to my new Genre tags.

Thank you!
