If you know how to work with ActiveX from MS Excel VBA, then there is no problem.

E.g. (demo.vbs):

Set f = CreateObject("CacheActiveX.Factory")
Set rs = CreateObject("CacheActiveX.ResultSet")
If Not f.IsConnected() Then

  f.Connect("cn_iptcp:127.0.0.1[1972]:SAMPLES:_SYSTEM:SYS")

  Set rs=f.DynamicSQL("select TOP 3 * from Sample.Person")
  rs.Execute()
  while rs.Next
    WScript.Echo rs.Get("SSN") 'print of field SSN for first three rows from the table Sample.Person
  wend

  rs.Close()
  Set person = f.Static("Sample.Person")
  age=person.CurrentAge(45678) 'call of method of class Sample.Person

  WScript.Echo age
End If

Running a Query in Visual Basic

If you only need SQL access, then will be easier to create a view (CREATE VIEW), if need both, then - %CacheSQLStorage, e.g.:

Class demo.A Extends %Persistent
{

Property P1;

Property P2;

ClassMethod Fill()
{
  d ..%KillExtent()
  
  f i=1:1:3 {
    s t=..%New()
    s t.P1="P1_"_i
    s t.P2="P2_"_i
    d t.%Save()
  }
}

Storage Default
{
<Data name="ADefaultData">
  <Value name="1">
    <Value>%%CLASSNAME</Value>
  </Value>
  <Value name="2">
    <Value>P1</Value>
  </Value>
  <Value name="3">
    <Value>P2</Value>
  </Value>
</Data>
<DataLocation>^demo.AD</DataLocation>
<DefaultData>ADefaultData</DefaultData>
<IdLocation>^demo.AD</IdLocation>
<IndexLocation>^demo.AI</IndexLocation>
<StreamLocation>^demo.AS</StreamLocation>
<Type>%Library.CacheStorage</Type>
}

}

Class demo.B Extends %Persistent [ Final, StorageStrategy = Default ]
{

Parameter READONLY = 1;

Property P2;

Storage Default
{
<SQLMap name="BDefaultData">
  <Data name="P2">
    <Piece>3</Piece>
  </Data>
  <Global>^demo.AD</Global>
  <RowIdSpec name="1">
    <Expression>{L1}</Expression>
    <Field>ID</Field>
  </RowIdSpec>
  <Subscript name="1">
    <Expression>{ID}</Expression>
  </Subscript>
  <Type>data</Type>
</SQLMap>
<StreamLocation>^demo.AS</StreamLocation>
<Type>%CacheSQLStorage</Type>
}

}

Result:

Ok, exclusively for fun.

I made some improvements and now my score is 9, but if you try very hard, even - 0!
Who less ? ;)

Here is the code:

Class ITPlanet.Task2 [ Abstract ]
{

Parameter p = {$zwbunpack("㤸㜶㔴㌲㄰")};

ClassMethod main() As %String
{
 q ..#p
}

}

Class ITPlanet.Test [ Abstract ]
{

ClassMethod length(
  class = {$classname()},
  method = "main") As %Integer [ CodeMode = expression ]
{
##class(%Dictionary.MethodDefinition).IDKEYOpen(class, method).Implementation.Size
}

ClassMethod test(makeDeploy = {$$$NO})
{
  ;do ##class(ITPlanet.Test).test()

  set classname="ITPlanet.Task2"
  set check=9876543210
  do:makeDeploy $system.OBJ.MakeClassDeployed(classname)
  set result=$classmethod(classname,"main")
  write !,result,!,check,
        !,"correct: ",$select(result=check:"yes",1:"no"),
        !,"length: ",..length(classname)
}

}

You can use the class %ZEN.proxyObject, e.g.:

Class demo.Customer Extends %RegisteredObject
{

Property p1 As %String;

Property p2 As %String;

Property list As %Collection.ListOfDT;

/// d ##class(demo.Customer).Test()
ClassMethod Test()
{
  s customer=##class(demo.Customer).%New()
  s customer.p1="p1"
  s customer.p2="p2"
  s customer.list=##class(%ListOfDataTypes).%New()
  d customer.list.InsertList($lb(1,"two",,"four"))
  
  s appointment=##class(%ZEN.proxyObject).%New()
  s appointment.a1="a1"
  s appointment.a2="a2"
  s appointment.list=##class(%ListOfDataTypes).%New()
  d appointment.list.InsertList($lb(2,3,"test",8))
  
  ; Cancellation
  s response=##class(%ZEN.proxyObject).%New()
  s response.Code="Cancellation"
  s response.Info="Info_Cancellation"
  w response.Code,":",! d response.%ToJSON(,"2aelow")
  
  d response.%Clear()

  ; Customer
  s response.Code="Customer"
  s response.Info=customer
  
  w !!,response.Code,":",! d response.%ToJSON(,"2aelow")

  d response.%Clear()

  ; Appointment
  s response.Code="Appointment"
  s response.Info=appointment
  
  w !!,response.Code,":",! d response.%ToJSON(,"2aelow")
}

}

USER>d ##class(demo.Customer).Test()
Cancellation:
{
  "Code":"Cancellation",
  "Info":"Info_Cancellation"
}
 
Customer:
{
  "Code":"Customer",
  "Info": {
    "p1":"p1",
    "p2":"p2",
    "list":["1","two","","four"]
  }
}
 
Appointment:
{
  "Code":"Appointment",
  "Info": {
    "a1":"a1",
    "a2":"a2",
    "list":[2,3,"test",8
    ]
  }
}
