Update a collection

Posted on by Community Power Pla... Microsoft Employee

Hello Friends,

I have a collection with name, type and number, I need a way to check if the record with the same number exists in my collection, update it, if not add it to the collection.

I did a test but nothing working.

Any idea?

Thanks in advance.

Try this:

If(
!IsBlank(LookUp(your_collection_name, Number=1)),
Collect(your_collection_name, {Name=“Name”, Type=“Type” And Number=1})
)

Hi @Anonymous ,
The below is a possible structure you could use - you will need to adapt the names.
If( CountRows( MyListName, NumberYouHave )>0, UpdateIf( MyListName, MyNumberField = NumberYouHave, { Field1:NewValue1 Field2:NewValue2 } ), Patch( MyListName, Defaults(MyListName), { MyNumberField:NumberYouHave Field1:NewValue1 Field2:NewValue2 } ) )

Please click Accept as solution if my post helped you solve your issue. This will help others find it more readily. It also closes the item. If the content was useful in other ways, please consider giving it Thumbs Up.

I am new at this, so I did not get it very clear.
If( CountRows( MyCollection, Name of the collection column )>0, UpdateIf( Collection, Column collection= Number text box, { Field1:NewValue1 Field2:NewValue2 } ), Patch( myCollection, Defaults(myCollection), { MyNumberField:NumberYouHave Field1:NewValue1 Field2:NewValue2 } ) )
Something like that?

Thank you for your answer, why I should use number 1?

You should not use number 1: it’s just a placeholder. Instead you should put the number you want to check for within the collection.

Hi @Anonymous ,
You need to understand the Patch and UpdateIf syntax to apply this to your needs.
Both myself and @mdevaney can help you here - once you apply the structure to your fields, table and control names, please tag one of us and we will fix whatever you do not get correct.
