Issue to translate a query from SQL to Appian

This is another example of the issue:

Have this Cade ID and we want the last date with "LogText"= "Updated", that should be 10/30/2024:

IDCase	Status
24491	Active

IDHistory	IDCase	LogText	CreatedDT
499353	24491	Created	10/14/24 6:24
499356	24491	Updated	10/14/24 6:25
499357	24491	Updated	10/14/24 6:25
499418	24491	Assigned	10/14/24 8:37
499419	24491	Locked	10/14/24 8:37
499420	24491	Assigned	10/14/24 8:41
499421	24491	Updated	10/14/24 8:42
499458	24491	Updated	10/14/24 12:54
499459	24491	Locked	10/14/24 12:55
499460	24491	Assigned	10/14/24 12:56
499461	24491	Locked	10/14/24 12:56
499462	24491	Updated	10/14/24 12:56
1267064	24491	Updated	10/30/24 6:53

So for example if the Filter for the dates are From 10-14-2024 To 10-14-2024 or From 10-01-2024 To 10-29-2024, it'll display the IDHistory "499462" (the orange one).

But if the Filter for the dates are From 10-30-2024 To 10-30-2024 or From 10-01-2024 To 10-31-2024, it'll display the IDHistory "1267064" (the green one).

That's why I was looking for a way, that the Filter of the dates be apply on the result of the first filters, not at the same time as the others.

Hello, thank you for your response.

The problem persist cause the Filters in Appian applied at the same time, For example:

Have this Cade ID and we want the last date with "LogText"= "Updated", that should be 10/30/2024:

IDCase	Status
24491	Active

IDHistory	IDCase	LogText	CreatedDT
499353	24491	Created	10/14/24 6:24
499356	24491	Updated	10/14/24 6:25
499357	24491	Updated	10/14/24 6:25
499418	24491	Assigned	10/14/24 8:37
499419	24491	Locked	10/14/24 8:37
499420	24491	Assigned	10/14/24 8:41
499421	24491	Updated	10/14/24 8:42
499458	24491	Updated	10/14/24 12:54
499459	24491	Locked	10/14/24 12:55
499460	24491	Assigned	10/14/24 12:56
499461	24491	Locked	10/14/24 12:56
499462	24491	Updated	10/14/24 12:56
1267064	24491	Updated	10/30/24 6:53

So for example if the Filter for the dates are From 10-14-2024 To 10-14-2024 or From 10-01-2024 To 10-29-2024, it'll display the IDHistory "499462" (the orange one).

Hi Stefan, our main goal is to select the last "Updated" history of each "CASE", because it can have multiple updates, and apply the filter of a date range to that selection.

ceciliaa9949 let me try and summarize what i understood

You have two tables:
- Main Table (CASE): Contains IDCase and Status for cases.
- Secondary Table (HistoryCase): Stores the historical movements (LogText, CreatedDT) for each case.
The requirement:
- Find the last "Update" (LogText = 'Updated') for each case.
- Exclude cases with Status = 'Close'.
- Apply a date range filter on the CreatedDT field (e.g., from 2024-11-01 to 2024-11-30).
- Order the results by IDCase.
Current SQL solution:
- A subquery identifies the latest update for each case.
- A date range filter is applied on the CreatedDT field in the final result.

Here’s how to translate the SQL query into Appian:

Record Type Setup: Ensure that HistoryCase is a record type with a relationship to the CASE record type.
Appian Query for Aggregation: follows next message <CODE>

Explanation of the Solution:

Aggregation Fields: Group by IDCase to aggregate data for each case.
Measure: Use the MAX function to fetch the latest CreatedDT for each case.
Filters:
- Only include rows where LogText starts with "Updated."
- Exclude cases with Status = 'Close' using a filter on the CASE record type.
- Filter the results to a specific date range using CreatedDT.

Paging: Adjust the batchSize as needed.

Filters in Appian are always applied at the same time.

I do not fully understand what you are doing with this data. If you share your thoughts, we might be able to come up with some ideas.
