SQL - Multiple conditions, numerous versions of a record, modified date

Greetings,

 

I need to filter a sql dB utilizing multiple filter options where there are many ‘versions’ of a record. Based on the users filter selection(s) I want to bring back the most up-to-date record based on the ‘Modified Date’ column.  I’m thinking Max might work for this but could use some guidance on the formula so it applies to all possible selections.  This sql table has 239k records so I cannot collect them into my app. 5425B014-141E-48C9-ACAF-75EA180CB90D.png

I personally think this might be easier to do on the SQL side by using a view or Stored procedure rather than depending on PowerApps. 

 

Then use the view/stored proc to bring you the "latest" record you looking for.

 

This will help App performance.

 

Let me know if you need more information.

Hi @KickingApps ,

Could you please share a bit more about your scenario?

Do you want to display  most up-to-date records within the Data Table based on the "Modified Date" column?

 

Based on the needs that you mentioned, I think the combination of GroupBy function, AddColumns function and DropColumns function could achieve your needs.

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

Add a Data Table control within your app, set the Items property of the Data Table to following:

DropColumns(
AddColumns(
GroupBy(
Filter(Datasource, RecordNbr = ddRecordNbr.Selected.Text || State = ddState.Selected.Text || Author = ddAuthor.Selected.Text),
"RecordNbr",
"GroupData"
),
"Author",
First(SortByColumns(GroupData, "Modified Date", Descending)).Author,
"State",
First(SortByColumns(GroupData, "Modified Date", Descending)).State,
"Modified Date",
First(SortByColumns(GroupData, "Modified Date", Descending)).'Modified Date'
),
"GroupData"
)

Then enable corresponding fields within the Data Table control, then the filtered records would be shown up.

 

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