Lua How do you return db.query integer?

[mackerel]

I need healthmax of my character but it returns true, instead of a number

        local currentHealth = db.query("SELECT `healthmax` FROM `players` WHERE `players`.`id` = " .. getPlayerGUID(oldPlayer) .. ";")
        print(currentHealth)

using tfs 1.0

local resultId = db.storeQuery("SELECT `healthmax` FROM `players` WHERE `players`.`id` = " .. getPlayerGUID(oldPlayer) .. ";")
if resultId ~= false then
    print(result.getDataInt(resultId, "healthmax"))
    result.free(resultId)
end
