I just want Date, Time, Name and Value

Code:

-- get past hour data (3600 seconds)
logtime = os.time() - 60 * 60

-- list of objects by id
objects = {'Mätare'}

-- objects with logging enabled
query = 'SELECT address, datatype, name FROM objects WHERE disablelog=0'
for _, object in ipairs(db:getall(query)) do
  objects[ tonumber(object.address) ] = {
    datatype = tonumber(object.datatype),
    name = tostring(object.name or ''),
  }
end

-- csv buffer
buffer = { '"date","name","adress","value"' }

-- get object logs
query = 'SELECT src, address, datahex, logtime, eventtype FROM objectlog WHERE logtime >= ? ORDER BY id DESC'
for _, row in ipairs(db:getall(query, logtime)) do
  object = objects[ tonumber(row.address) ]

  -- found matching object and event type is group write
  if object and row.eventtype == 'write' then
    datatype = object.datatype

    -- check that object datatype is set
    if datatype then
      -- decode data
      data = knxdatatype.decode(row.datahex, datatype)

      -- remove null chars from char/string datatype
      if datatype == dt.char or datatype == dt.string then
        data = data:gsub('%z+', '')
      -- date to DD.MM.YYYY
      elseif datatype == dt.date then
        data = string.format('%.2d.%.2d.%.2d', data.day, data.month, data.year)
      -- time to HH:MM:SS
      elseif datatype == dt.time then
        data = string.format('%.2d:%.2d:%.2d', data.hour, data.minute, data.second)
      end
    else
      data = ''
    end

    -- format csv row
    logdate = os.date('%Y.%m.%d %H:%M:%S', row.logtime)
    csv = string.format('%q,%q,%q,%q', logdate, knxlib.decodega(row.address), object.name, tostring(data))

    -- add to buffer
    table.insert(buffer, csv)
  end
end

-- transform table to string for csv file
data1 = table.concat(buffer, '\r\n')

  -- make sure these settings are correctat
  local settings = {
    -- "from" field, only e-mail must be specified here

  }

  mime = require("mime")
  ltn12 = require("ltn12")
  local smtp = require('socket.smtp')
  local escape = function(v)
  return '<' .. tostring(v) .. '>'
  end

settings.from = escape(settings.from)
settings.rcpt = { escape(to) }

settings.source = smtp.message{
   headers = {
    to = to,
      subject = subject,
    },
   body = {
      preable = "This email contains 1 attachment.",
      [1] = {
