Sorting DBvar
 
A have a chart of items i have compiled with their various High and Low values marked out to form a range
I would like them displayed in ascending order, by @var.%i.Low and in the event of a tie, by @var.%i.High

I was using this to display at the moment

#FORALL %dbkeys(fishDiff) {#SAY {%format("&-25s &4d -&4d", %i, @fishDiff.%i.Low, @fishDiff.%i.High)}}

If you don't mind using Lua:
Code:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<cmud>
  <alias name="showfish" language="Lua">
    <value>local t = {}
for k, v in pairs(zs.var.fishDiff) do
  table.insert(t, {Key = k, Low = v.Low, High = v.High})
end
table.sort(t, function(a, b)
  if a.Low == b.Low then
    return a.High <= b.High
  else
    return a.Low <= b.Low
  end
end)
for i, v in ipairs(t) do
  print(string.format("%-25s %4d -%4d", v.Key, v.Low, v.High))
end</value>
  </alias>
</cmud>

Meh, copy/paste it into an alias manually. The forum breaks the xml parsing for < and >, I don't remember how to work around that offhand.

Attempt to index local 'b' (a nil value) (line 6)

Stack trace:
[string "code"]:6:in a Lua function
[C]:-1:in function "sort"
[string "code"]:5:in main chunk"
