Expression Rule:

cast('type!{urn:com:appian:types:HSM}HSM_Elements?list',
a!queryEntity(
entity: cons!HSM_Entity,
query: a!query(
pagingInfo: a!pagingInfo(
startIndex: 1,
batchSize: 5000,
sort: a!sortInfo(
field:"S_No",
ascending: true,
)
)
)
).data
)

I want to retrieve every data without Status field from database.

Is it possible to retrieve using rules?

You can use the 'selection' parameter in the a!query() to pass all the other field names except status.

I have added 'selection' paramater in the a!query. And also passed all fields excep status.

But it shows an error like in above template.

My Updated Code:

cast('type!{urn:com:appian:types:HSM}HSM_Elements?list',
a!queryEntity(
entity: cons!HSM_Entity,
query: a!query(
selection:a!querySelection(
Columns: a!queryColumn(
field:{"S_No","Employee_Name","Employee_Id","Employee_Email_Id","Query","Comments","Date"},
)
),
pagingInfo: a!pagingInfo(
startIndex: 1,
batchSize: 5000,
sort: a!sortInfo(
field:"S_No",
ascending: true,
)
)
)
).data
)

A queryColumn can only have one column name. And hence you will have to add multiple query columns.
Check the code below..

cast('type!{urn:com:appian:types:HSM}HSM_Elements?list',
  a!queryEntity(
    entity: cons!HSM_Entity,
    query: a!query(
      selection:a!querySelection(
        columns: {
          a!queryColumn(
            field:"S_No",
          ),
          a!queryColumn(
            field:"Employee_Name",
          ),
          a!queryColumn(
            field:"Employee_Id",
          )
        }
      ),
      pagingInfo: a!pagingInfo(
        startIndex: 1,
        batchSize: 5000,
        sort: a!sortInfo(
          field:"S_No",
          ascending: true,
        )
      )
    )
  ).data
)
