Reading HR-XML from DB

Question

When I read a table with HR-XML, I tap into a view

CREATE VIEW [dbo].[vwUser] 
AS
WITH XMLNAMESPACES (DEFAULT 'http://ns.hr-xml.org/2007-04-15')
SELECT    UserID, login, passhash, 
    PersonName.value('(/PersonName/GivenName)[1]', 'nvarchar(max)') AS firstname,
    PersonName.value('(/PersonName/MiddleName)[1]', 'nvarchar(max)') AS middlename,
    PersonName.value('(/PersonName/FamilyName)[1]', 'nvarchar(max)') AS lastname,
    PersonName.value('(/PersonName/Affix)[1]', 'nvarchar(max)') AS postfix,

    homepath, loginTarget, 
 ....

Which is later SELECTED via

variables.lstCol = "UserID,login,passhash
    ,firstname,middlename,lastname,postfix

....

query function getOne(required string userid) output="no" access="remote"   {

variables.QueryService.addParam(value = arguments.userID, cfsqltype="cf_sql_varchar");

var result = variables.QueryService.execute(sql="SELECT #variables.lstCol# FROM dbo.vwUser WHERE Deleted = 0 AND userid = ?");

if (result.getResult().recordcount == 1)
    return result.getResult();

// Create blank row
var qryBlank = QueryNew(variables.lstCol);
QueryAddRow(qryBlank);

return qryBlank;
}

Is this a good approach?
