questing.lua issue

[Syntaax 5]

So i bought an IS few years ago from ProfessorEnte. Now i tryed to implement it and got this problem with his quest...

I dont want to recode the sql querys to an updated version.

Does anyone know how i could fix this issue? Could it be that a table got init with "null" and thats cause the Problem?

 

Line:58

os.execute('mysql '..pre..' -e'..string.format('%q',query)..' > '..fi) -- für MySQL55

Syserr

questing.lua:58: attempt to index a nil value

 

questing.lua part

mysql_query = function(query)
    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),{},{}
    --os.execute('mysql '..pre..' --e='..string.format('%q',query)..' > '..fi) -- für MySQL51
    os.execute('mysql '..pre..' -e'..string.format('%q',query)..' > '..fi) -- für MySQL55
    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[i],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
    return out
end

I do not recommend using that function for many reasons. Install mysql_direct_query
