Intersect two array of objects

[Anonymous]

Hi, I have two arrays of objects and I would like to intersect them with the intersection expression. Is that some how possible?

Array1

[

  {

    "NR": "32097"

  },

  {

    "NR": "32050"

  },

  {

    "NR": "00005"

  }

]

Array2

[

  {

    "NR": "32050",

    "GUID": "c6839d05-d326-df11-987c-00155d003a1e"

  },

  {

    "NR": "12005",

    "GUID": "ca72aef5-fae5-e511-80de-5065f38a69b1"

  },

  {

    "NR": "12006",

    "GUID": "f2ff98b8-2793-de11-8125-00155da49631"

  }

]

I would like to intersect the two arrays based on "NR"

intersection(body('Array1')?['NR'],body('Array2')?['NR'])

and get something like

Result

[

  {

    "NR": "32050",

    "GUID": "c6839d05-d326-df11-987c-00155d003a1e"

  }

]

Can I do that with out using a "for-each" loop? So far I have not found the right soltuion.

Your help is appreciated.

Hello @Anonymous 

You can't use intersection function because it expects two arrays of the same object, and in your case these objects are different (first one has NR field only and second one has it and GUID).

So you will probably need a for each expression to get Array1 items, and filter them in the Array2.

Hope it helps!

Hi @Anonymous ,

It seems that using expression alone cannot achieve such a demand.

Please refer to the following configuration:

@v-bacao-msft, @fchopo Thanks for your replies.

I will go with v-baco's solution than. However to compare external systems to a CDS table an then trigger action in CDS, it would be greate to have such functionality. Would save a couple api-calls.

Kind regards
