Updating Date values in a collection

[PJBruen]

Hi, 

I have a collection which has a number of date fields.

Can anyone advise what command I can run to change the date values in that collection?

For example, if I want to change all dates that match 01/01/2020 (UK format) to be 31/12/2020.

Presumably it's an UpdateIf statement required, but PowerApps is not liking my syntax so far.

Many thanks

Paul

Created a sample collection as below:

ClearCollect(colDates, [{Title: "Sam", Date: "11/12/2020"}, {Title: "David", Date: "11/10/2020"}, {Title: "John", Date: "11/12/2020"}, {Title: "Jason", Date: "11/12/2020"}])

Placed a button on the screen and OnSelect wrote following formula:

UpdateIf(colDates,Value.Date="11/12/2020",{Value: {Title: Value.Title, Date: "11/09/2020"}})

On clicking the button, it uses UpdateIf function to check the date value "11/12/2020" in the collection and replaces with "11/09/2020" for each item in the collection.

I hope this will be useful for you.

Hi, @rsaikrishna - thanks for your reply.

I'm still having a little trouble getting this right. Here's what I have:

colStressTestTimeline

The formula I have is: UpdateIf(colStressTestTimeline, KeyMilestone_StartDate="24/09/2020", {Title: "2019/2019 - BES", KeyMilestone_StartDate: "01/01/1900"});

I know this slightly differs to yours, but the syntax of value.KeyMilestone_StartDate didn't appear valid.

Any ideas?

Thanks. Paul

Sorry - not sure I can reply to the meeting request..

@PJBruen 

In your collection, do you see Records or direct values as shown in your screen shot?

If you see direct values, then you do not need to use value.KeyMilestone_StartDate. 

When you use the following formula:

UpdateIf(colStressTestTimeline, KeyMilestone_StartDate="24/09/2020", {Title: "2019/2019 - BES", KeyMilestone_StartDate: "01/01/1900"});

Do you see any issues with above formula? If so, share the details of the error.

Hi @rsaikrishna 

The collection is as per the screenshot, so I see records that have been populated by a ClearCollect call against a Sharepoint site.

Try using following:

UpdateIf(colStressTestTimeline, KeyMilestone_StartDate=Date(2020,09,24), {Title: "2019/2019 - BES", KeyMilestone_StartDate: Date(1900,1,1)});
