Hi,

Hope the below code helps

a!localVariables(
  local!dataSet: a!queryEntity(
    entity: "< DSE_Constant >",
    query: a!query(
      logicalExpression: a!queryLogicalExpression(
        operator: "AND",
        filters: {
          a!queryFilter(
            field: "rollnumber",
            operator: "in",
            value: { "AB000", "AB0001" }
          )
        },
        ignoreFiltersWithEmptyValues: true
      ),
      pagingInfo: a!pagingInfo(startIndex: 1, batchSize: 50)
    ),
    fetchTotalCount: true
  ),
  if(
    local!dataSet.totalCount = length({ "AB000", "AB0001" }),
    true(),
    false()
  )
)

The code has no issues, but you need to add a null check like below to achieve your requirement:

if(
  isnull(
    a!queryEntity(
      entity: < DSE_Constant > ,
      query: a!query(
        logicalExpression: a!queryLogicalExpression(
          operator: "AND",
          filters: {
            a!queryFilter(
              field: "siteid",
              operator: "in",
              value: { "AB000", "AB0001" }
            )
          },
          ignoreFiltersWithEmptyValues: true
        ),
        pagingInfo: a!pagingInfo(startIndex: 1, batchSize: 50)
      ),
      fetchTotalCount: false
    ).data
  ),
  "Not Present",
  "Present"
)

Here's a sample code:

a!queryEntity(
  entity: <DSE_CONSTANT>,
  query: a!query(
    logicalExpression: a!queryLogicalExpression(
      operator: "AND",
      filters: {
        a!queryFilter(
          field: "phoneNumber",
          operator: "in",
          value: { "12345", "56789" }
        )
      },
      ignoreFiltersWithEmptyValues: true
    ),
    pagingInfo: a!pagingInfo(startIndex: 1, batchSize: 50)
  ),
  fetchTotalCount: false
).data

In that How can I check with Multiple values (two or three) .

Hi,

You can use the a!queryEntity() function to retrieve data from the database with the values as filters and based on the results you can return the boolean value.
