Caso exista, ver se a função split é chamada correctamente (argumentos a mais/menos)

Minha função é essa:

 

function split(str, delim, maxNb)
    if str == nil then return str end
    if string.find(str, delim) == nil then return { str } end
    if maxNb == nil or maxNb < 1 then maxNb = 0 end
    local result = {}
    local pat = "(.-)" .. delim .. "()"
    local nb = 0
    local lastPos
    for part, pos in string.gfind(str, pat) do
        nb = nb + 1
        result[nb] = part
        lastPos = pos
        if nb == maxNb then break end
    end
    if nb ~= maxNb then result[nb + 1] = string.sub(str, lastPos) end
    return result
end

mysql_query = function(query)
    local version = 55
    if not pre then
        local rt = io.open('CONFIG','r'):read('*all')
        pre,_= string.gsub(rt,'.+PLAYER_SQL:%s(%S+)%s(%S+)%s(%S+)%s(%S+).+','-h%1 -u%2 -p%3 -D%4')
    end
    math.randomseed(os.time())
    local fi,t,out = 'mysql_data_'..math.random(10^9)+math.random(2^4,2^10),{},{}
    if version == 51 then
        os.execute('mysql '..pre..' --e='..string.format('%q',query)..' > '..fi)
    elseif version == 55 then
        os.execute('mysql '..pre..' -e'..string.format('%q',query)..' > '..fi)
    else
        return 0
    end
    for av in io.open(fi,'r'):lines() do table.insert(t,split(av,'\t')) end; os.remove(fi);
    for i = 2, table.getn(t) do table.foreach(t,function(a,b)
        out[i-1]               = out[i-1] or {}
        out[i-1][a]            = tonumber(b) or b or 'NULL'
        out[t[1][a]]           = out[t[1][a]] or {}
        out[t[1][a]][i-1]      = tonumber(b) or b or 'NULL'
    end) end
    out.__lines = t[1]
    return out
end
