未返回正确的值

你好，我有两个函数，一个返回一个值

function AddPlayer(steamID, source)
    for i,p in ipairs(players) do
        if steamID == p[1] then
            players[i] = {p[1], p[2], source}
            return
        end
    end

    local initialPoints = GetInitialPoints(steamID)
    print(initialPoints)
    table.insert(players, {steamID, initialPoints, source})
end

function GetInitialPoints(steamID)
    local points = 0
    print(steamID)
    MySQL.Async.fetchAll("Select priority FROM queue where `identifier`= @identifier",
    {
        ['@identifier'] = steamID,
    },
    function(resp)
        points = resp[1].priority
        print(points)
    end)
    return points
end

所以打印的实际值是正确的（10,000），但是在函数AddPlayer的返回值中，当我打印初始点数时，它打印0，这是我声明变量时设置的值，但实际上应该是我设置的点数值。
