Forall on collection with isMatch()

I am trying to use a ForAll on a collection called TestInfo that will check if the "Time" column will match "5:00".

 

I tried

ForAll(TestInfo, IsMatch(TestInfo.Time, "3:00")).

 

Error Message says "Invalid argument type (table). Expecting a Text value instead". How would i get the text value of the collection items and does the Forall return a new table with a true and false values ?

Re: Forall on collection with isMatch()

Hi @Buddy2019 ,

Could you please share a bit more about your scenario?

Do you want to detect if the time value within the Time column in your TestInfo collection match "5:00"?

 

Based on the screenshot that you provided, I think the Time column (in your TestInfo collection) contains a Table value. So the result the TestInfo.Time formula returned is a Table value rather than Text value. But the first argument of the IsMatch function is required to provide a Text value.

 

I have made a test on my side, please take a try with the following workaround:8.JPG

Set the OnStart property of the App control to following:

 

ClearCollect(
             TestInfo,
             {ProductName: "PowerApps", Time: Table({StartTime: "07/26/2019 3:00 PM"}, {StartTime: "07/26/2019 12:00 PM"})},
             {ProductName: "MS Flow", Time: Table({StartTime: "07/26/2019 5:00 PM"}, {StartTime: "07/26/2019 6:00 PM"})}
)

The TestInfo data structure as below:13.JPG

 

Set the OnSelect property fo the "Execute Match" button to following (nested ForAll functions):

ForAll(
       TestInfo,
       ForAll(
              Time,
              If(
                  IsMatch(StartTime, "\d{1,2}\/\d{1,2}\/\d{4} 5:00 (AM|PM)"),
                  Collect(MatchRecords, {ProductName: ProductName, MatchedTime: StartTime})
              )
        )
)

On your side, you may type following:

ForAll(
       TestInfo,
       ForAll(
              Time,
              If(
                  IsMatch(StartTime, "\d{1,2}\/\d{1,2}\/\d{4} 5:00 (AM|PM)"),
                  Collect(
MatchRecords,
{
Column1: Column1,
Column2: Column2,
...
MatchedTime: StartTime
}
) ) ) )

Note: The Column1, Column2, ... represents the columns in your TestInfo collection.

Add a Data Table control, set the Items proeprty to following:

MatchRecords

When you press the "Execute Match" button, above Data Table control would be populated with matched records and corresponding matched time.

Re: Forall on collection with isMatch()

Hi @Buddy2019 

In answer to your question, the ForAll function doesn't return a table with true and false values. To do this, you can use the AddColumns function rather than ForAll. The syntax would look like this:

 

AddColumns(TestInfo, 
"TimeMatch",
IsMatch(Time, "5:00")
)

This function returns a table with a new column called TimeMatch. The field value will be true when the time matches 5:00.

The Concat function can help you extract text values from a table. There are more details here.

Re: Forall on collection with isMatch()

Hi @Buddy2019 

 

Try the following code:

 

ForAll(TestInfo, If(IsMatch(Text(TestInfo[@StartTime]), "3:00",MatchOptions.Contains),Collect(newcollection,TestInfo[@StartTime])))

 

ForAll does not create a new collection, you would have to create one withing ForAll

The above example will create a new collection for you
