Filter with datasource in if construction that evaluates true: different results then without if construction

I am trying to let my users choose to search recent data (which is cached in a collection) or all data (the sql datasource itself).

If I do

ClearCollect(ZoekDieren;SortByColumns(Filter('[dbo].[dier]_1';eZoekTekst.Text in naam);"identificatie_nummer_asiel";Descending))

I get expected results with a certain search string.

But If I do

ClearCollect(ZoekDieren;SortByColumns(Filter(If(!Toggle2.Value;'[dbo].[dier]_1';CachedDieren);eZoekTekst.Text in naam);"identificatie_nummer_asiel";Descending))

with toggle2.value=false (so !toggle2.value=true) I get only results from the first part of the table, so it is doing its delegation thing on me.

zoekdieren is the collection that is the items propert of my gallery, cacheddieren is collected from the table at app start
If I toggle I get different results altogheter so that is not the problem.
; not , is normal in holland

How can this be?

Hi @HansHeintz

I would try placing your If function outside of your Filter function. Perhaps that might solve your delegation problem?

ClearCollect(ZoekDieren; SortByColumns( If(!Toggle2.Value; Filter('[dbo].[dier]_1';eZoekTekst.Text in naam); Filter(CachedDieren ;eZoekTekst.Text in naam) ); "identificatie_nummer_asiel"; Descending ) )

HI @HansHeintz,

How many records stored in your SQL Table? More than 2000?

Based on the issue that you mentioned, I think this issue may be related to Delegation issue. When you load data from your '[dbo].[dier]_1' table into the CachedDieren collection, in default, it could only load 500 records from '[dbo].[dier]_1' table into the CachedDieren collection.

1) If the amount of your '[dbo].[dier]_1' table records is not more than 2000, please consider set the "Data row limit for Non-delegable queries" option to maximum value -- 2000 within Advanced settings of App settings of your app, then you could load 2000 records at most from '[dbo].[dier]_1' table into the CachedDieren collection, then try your formula again, check if the issue is solved.

2) If the amount of your '[dbo].[dier]_1' table records is more than 2000, please check and see if the alternative solution mentioned within the following thread would help in your scenario:

https://powerusers.microsoft.com/t5/General-Discussion/Pulling-in-large-ish-SQL-tables/m-p/243777#M71518

Set the OnStart property of the App control to following (I assume that there are 10000 records stored in your SQL Table😞

Concurrent( ClearCollect(col1, Filter('[dbo].[dier]_1', recordID >= 1 && recordID <= 2000)), ClearCollect(col2, Filter('[dbo].[dier]_1', recordID >= 2001 && recordID <= 4000)), ClearCollect(col3, Filter('[dbo].[dier]_1', recordID >= 4001 && recordID <= 6000)), ClearCollect(col4, Filter('[dbo].[dier]_1', recordID >= 6001 && recordID <= 8000)), ClearCollect(col5, Filter('[dbo].[dier]_1', recordID >= 8001 && recordID <= 10000)) ); ClearCollect(CachedDieren, col1, col2, col3, col4, col5)

Note: I assume that there is a Identity(1,1) column (e.g. recordID column) in your SQL Table to identify the row index.

then modify your formula as below:

ClearCollect(
ZoekDieren;
SortByColumns(
Filter(
If(!Toggle2.Value; '[dbo].[dier]_1'; CachedDieren);
eZoekTekst.Text in naam
);
"identificatie_nummer_asiel";
Descending
)
)

Or

ClearCollect(
ZoekDieren;
SortByColumns(
If(
!Toggle2.Value;
Filter('[dbo].[dier]_1', eZoekTekst.Text in naam),
Filter(CachedDieren, eZoekTekst.Text in naam)
);
"identificatie_nummer_asiel";
Descending
)
)

then re-load your app (fire the OnStart proprety of the App control), then check if the issue is solved.

Best regards,
