In my database I have geodata, logitude and latitude for database objects. 

Now I need to render a  Google Map for each object. It can be done, mostly simple with Maps Embed API and an iframe, or Maps Javascript API and full JS/HTML/CSS code.

Q: hat are ways to work with multiple transformed values at once?

For example, like this

<iframe
  width="450"
  height="250"
  frameborder="0" style="border:0"
  referrerpolicy="no-referrer-when-downgrade"
  src="https://maps.google.com/maps?q={latitude.value},{longitude.value}&hl=de&z=14&output=embed"
  allowfullscreen>
</iframe>

Is it a smarter way, to store the code in a separate MySQL column and query longitude/latitude into it?
