DISTINCT with sort, if and filter

[Tamer66]

Hello,

i have a gallery with sort, if and filter function. Now i want use the Distinct function to show the names 

only show once.

SortByColumns(
    DISTINCT(If(
        !IsBlank(searchField.Text);
        Filter(
            myContracts;
            StartsWith(
                Nachname;
                searchField.Text
            ) || StartsWith(
                Mitgliedsnummer;
                searchField.Text
            )
        );
        Filter(
            myContracts;
            ArtName = DropdownGew.SelectedText.Value
        )
    );
    "Mitgliedsnummer";
    If(
        SortDescending1;
        Descending;
        Ascending
    )
);Mitgliedsnummer)

Has anyone an idea?

Thanks

HI @Tamer66 

Can you try out the below expression to just get the distinct "Mitgliedsnummer":

SortByColumns(
    DISTINCT(If(
        !IsBlank(searchField.Text);
        Filter(
            myContracts;
            StartsWith(
                Nachname;
                searchField.Text
            ) || StartsWith(
                Mitgliedsnummer;
                searchField.Text
            )
        );
        Filter(
            myContracts;
            ArtName = DropdownGew.SelectedText.Value
        )
    );
    "Mitgliedsnummer");
    Result
    If(
        SortDescending1;
        Descending;
        Ascending
    )
)

The above expression will just return a one column table with all the distinct "Mitgliedsnummer".

In case you are looking for something that shows one entry per Mitgliedsnummer, then you may want to use the GroupBy function.

SortByColumns(
    GroupBy(If(
        !IsBlank(searchField.Text);
        Filter(
            myContracts;
            StartsWith(
                Nachname;
                searchField.Text
            ) || StartsWith(
                Mitgliedsnummer;
                searchField.Text
            )
        );
        Filter(
            myContracts;
            ArtName = DropdownGew.SelectedText.Value
        )
    );
    "Mitgliedsnummer";"Grouped");
    Result
    If(
        SortDescending1;
        Descending;
        Ascending
    )
)

This will create a grouped nested array of all the records corresponding to specific Mitgliedsnummer, and if you want to fetch a specific record in your gallery, you can filter each gallery item by performing filter queries on ThisItem.Grouped

Hope this Helps!

Hi @Tamer66 ,

Do you want to show distinct Mitgliedsnummer value within your Gallery?

Do you want to only show Mitgliedsnummer value within your Gallery?

Based on the formula that you provided, I think there is something wrong with it. I have made a test on my side, please consider take a try with the following workaround:

1. If you just want to show Mitgliedsnummer value within your Gallery:

 Set the Items property of the Gallery to following formula:

Distinct(
        SortByColumns(
                If(
                    !IsBlank(searchField.Text);
                    Filter(
                           myContracts;
                          StartsWith(Nachname; searchField.Text) || StartsWith(Mitgliedsnummer; searchField.Text)
                    );
                    Filter(
                            myContracts;
                            ArtName = DropdownGew.SelectedText.Value
                    )
               ),
               "Mitgliedsnummer";
               If(SortDescending1; Descending; Ascending)
        ),
        "Mitgliedsnummer"
)

2. If you want to show distinct Mitgliedsnummer value along with other column values within your Gallery, I think an nested Gallery and GroupBy function could achieve your needs:

Set the Items property of the Outer Gallery (Parent Gallery, Gallery1) to following:

GroupBy(
        SortByColumns(
                If(
                    !IsBlank(searchField.Text);
                    Filter(
                           myContracts;
                          StartsWith(Nachname; searchField.Text) || StartsWith(Mitgliedsnummer; searchField.Text)
                    );
                    Filter(
                            myContracts;
                            ArtName = DropdownGew.SelectedText.Value
                    )
               ),
               "Mitgliedsnummer";
               If(SortDescending1; Descending; Ascending)
        ),
        "Mitgliedsnummer",
        "GroupData"
)

Then within the Outer Gallery, add a nested Gallery (Gallery2), set the Items property to following:

ThisItem.GroupData

within the nested Gallery, you could add some Label controls to display other column values from your "myContracts" data source using the following formula:

ThisItem.Nachname

ThisItem.ArtName

...

Please take a try with above solution, then check if the issue is solved.

Hi

thanks for your cool support. This helps me realy.

[David8]

I have tried following the example shown here because I have exactly the same issue. I am trying to get only distinct values. The formula below works perfectly but when I try to use Distinct, I am unable to get any results. Could someone help me please identify what I am doing wrong?

SortByColumns(
Filter(
'Vendor List',
TextSearchBox1.Text in ID || TextSearchBox1.Text in Title || TextSearchBox1.Text in Tier.Value || TextSearchBox1.Text in 'Vendor Status'.Value || TextSearchBox1.Text in 'Vendor Posture'.Value || TextSearchBox1.Text in 'SVM Analyst'.DisplayName
),
"Title",
If(
SortDescending1,
Descending,
Ascending
)
)
