As you read through the rows of returned data (including the unexpected extras), what rows are being returned that don't match the desired parameters? In what way do those rows fail to meet your expectations? This is important to know to determine what the issue might be. If you're able to try again, could you post the full code of that version of the query?

Hello Mike,

Thanks for the response.

I did tried this approach earlier, it is returning me data but instead of 22 it is giving me 49 rows etc which is not appropriate. So i am kind of lost on it.

I don't understand why you can't just use QueryLogicalExpression nesting to accomplish this. Your example code posted above already contains an example of nested QLEs so you already understand how it should be structured. In pseudocode all you'd need to add for the source/date combinations is something like this:

logicalExpressions: {
  a!queryLogicalExpression(
    operator: "OR",
    logicalExpressions: {
      
      /* first source */
      a!queryLogicalExpression(
        operator: "AND",
        filters: {
          /* Query Filter for Source = AAA */
          (...)
          /* Query Filter on Date Field AAA */
          (...)
        }
      ),
      
      /* second source */
      a!queryLogicalExpression(
        operator: "AND",
        filters: {
          /* Query Filter for Source = BBB */
          (...)
          /* Query Filter on Date Field BBB */
          (...)
        }
      )
    }
  )
},

makes sense, now i will look for other options as you mentioned. Thanks a lot for you time and prompt response.

Thanks Stefan..

No. In SQL code you can do a subselect and fetching data and use it in a condition. This is not possible in Appian. So putting a queryFilter as a condition into an if statement will not work.

the data returned is just written to another tables but nothing can be done later.

Let me make it simple, would this type of condition work(not returning correct data)..

Do i have to write it differently??

if(
a!queryFilter(
field: "caseSourceRefId",
operator: "<>",
value: cons!FAS_REF_ID_CASE_SOURCE[12],
),

a!queryFilter(
field: "requestReceivedOn",
operator: ">=",
value: gmt(
todatetime(
workday(
local(now(), "America/New_York"),
cons!FAS_MAX_DAYS_TO_INCREASE_PRIORITY,
ri!holidays
) & " " & totime("16:00 PM")
)
)
),
a!queryFilter(
field: "requestReceivedDateTimeFromExtSource",
operator: ">=",
value: gmt(
todatetime(
workday(
local(now(), "America/New_York"),
cons!FAS_MAX_DAYS_TO_INCREASE_PRIORITY,
ri!holidays
) & " " & totime("16:00 PM")
)
)
)
),

This is very confusing ...

What do you do with the returned data? Would it be an option to just fetch both fields and decide later in the logic?

i am adding the actual code i am using for additional info, please check....

ri!dailyPriorityCriteria would just get the cases based on the filters we pass above..

IN this code, we only have the filetes for requestReceivedOn date field, now we have new field "requestReceivedfromexternalsource" which is specific to some sources.

a!queryEntity(

Hello Stefan,

Thank you for the response.

Source is another column in the same Table and coming from table in this case. So i have columns... "Source", "DateFieldAAA", "DateFieldBBB" etc.

When Source = AAA, query filter on "DateFieldAAA" and when source = BBB, query filter on "DateFieldBBB".

Even to use applywhen() condition, i have to first get the source.

i tries something like this, which i am sure would not help me.

a added a!queryselection(column: "source"), and under filters:

if(

a!queryFilter(
field: "source",
operator: "=",
value: "AAA"
),

a!queryFilter(
field: "DateFieldBBB",
operator: ">=",
value: gmt(
todatetime(
workday(
local(now(), "America/New_York"),
-10,
ri!holidays
) & " " & totime("16:00 PM")
)
),

a!queryFilter(
field: "DateFieldAAA",
operator: ">=",
value: gmt(
todatetime(
workday(
local(now(), "America/New_York"),
-10,
ri!holidays
) & " " & totime("16:00 PM")
)
),

)

Using a simple applyWhen would allow you to enable certain filters on conditions. My question is: How is this "source" defined and where is the value coming from?

Hi,

Are you trying to filter or query data based on the selected source. Provide some additional details why you want to filter data based on source?
