In this case, it will be easier to temporarily dump the data into globals. Then you can access this data at any time, including through %ScrollableResultSet.

Here is a small example:

ClassMethod tt() [ Language = tsql, ReturnResultsets, SqlName = mycls, SqlProc ]
{
  drop table if exists mytemp1,mytemp2
  select name,dob,spouse into mytemp1 from Sample.Person where name like 'A%'
  select name,age,home_city,home_state into mytemp2 from Sample.Person where home_state = 'MA'
}

ClassMethod Test()
{
  d ##class(%SQL.Statement).%ExecDirect(,"call dc.mycls()")
  
  d ##class(%SQL.Statement).%ExecDirect(,"select * from mytemp1").%Display()
  d ##class(%SQL.Statement).%ExecDirect(,"select * from mytemp2").%Display()

  ; and even so
  d ##class(%SQL.Statement).%ExecDirect(,"select * from mytemp1 cross join mytemp2").%Display()
}

One of the possible options:

ClassMethod odbcTest() As %Integer [ ReturnResultsets, SqlName = PersonSets2, SqlProc ]
{
  #dim %sqlcontext As %ProcedureContext
  if '$isobject($Get(%sqlcontext)) { set %sqlcontext = ##class(%ProcedureContext).%New() } 

  s tReturn = 0

  s conn=##class(%SQLGatewayConnection).%New()
  s sc=conn.Connect("TEST Samples","_system","SYS") //datasource
  if $$$ISOK(sc) {
    d conn.AllocateStatement(.h1)
    d conn.Prepare(h1,"select name,dob,spouse from sample.person where name %STARTSWITH 'A'")
    d conn.Execute(h1)
    d %sqlcontext.AddResultSet(conn.getResultSet(h1))
    d conn.AllocateStatement(.h2)
    d conn.Prepare(h2,"select name,age,home_city,home_state from sample.person where home_state = 'MA'")
    d conn.Execute(h2)
    d %sqlcontext.AddResultSet(conn.getResultSet(h2))
    s tReturn = 1
  }else{
    s sqlcode=$system.Status.StatusToSQLCODE(sc,.msg)
    s %sqlcontext.%SQLCODE = sqlcode, %sqlcontext.%Message = msg
  }
  q tReturn
}

Output:

SAMPLES>d ##class(%SQL.Statement).%ExecDirect(,"call Sample.PersonSets2()").%Display()
...

Surely there is a way to make it even easier.

It's clearer now, this is the tricks of Excel, which convert the string 01022000 to the number 1022000.
In your case, try changing the cell type from General to Text.

PS: when generating Excel reports, I use the Date cell type (short format DD.MM.YYYY), and from Caché/IRIS I return the %Date type.
The components that I use already know how to translate the internal representation of the date 01.02.2000 from the Caché/IRIS format (58105) to Excel (36557) and vice versa.

Thanks for the comment. I tested only on the provided data. The second option requires improvement.

 
size = 72
 
size = 69

Query FilterBy(
  Name As %String = "",
  Age As %Integer = "") As %SQLQuery(CONTAINID = 1, SELECTMODE = "RUNTIME") [ SqlName = SP_Sample_Filter_By, SqlProc ]
{
SELECT TOP 5 ID, Name, Age, SSN FROM %ALLINDEX Sample.Person WHERE 
(:Name IS NULL or Name %STARTSWITH :Name)
AND
(:Age IS NULL or Age >= :Age)
}
This kind of query ends up preventing Caché SQL compiler from optimizing using index based on each of the criteria made optional.

What is your conclusion based on?
If you check the plans of this query for different combinations of parameters, then the corresponding indexes are used (it is assumed that the table was previously configured via TuneTable).

select * from Sample.SP_Sample_Filter_By('s')


SELECT TOP 5 ID, Name, Age, SSN FROM %ALLINDEX Sample.Person WHERE 
('s' IS NULL or Name %STARTSWITH 's')
AND
(NULL IS NULL or Age >= NULL)
select * from Sample.SP_Sample_Filter_By(,47)


SELECT TOP 5 ID, Name, Age, SSN FROM %ALLINDEX Sample.Person WHERE 
(NULL IS NULL or Name %STARTSWITH NULL)
AND
(47 IS NULL or Age >= 47)
select * from Sample.SP_Sample_Filter_By('s',47)


SELECT TOP 5 ID, Name, Age, SSN FROM %ALLINDEX Sample.Person WHERE 
('s' IS NULL or Name %STARTSWITH 's')
AND
(47 IS NULL or Age >= 47)
