Google Maps from SQL table

I suggest using the Google Maps JavaScript API.

The process of converting an address to Lat/Lng is called Geocoding, which is supported by the JavaScript API.  More details here:
http://code.google.com/apis/maps/documentation/javascript/services.html#Geocoding

I hope this helps.

and just f.y.i., with the API, you don't need to convert to Lat-Lng manually... the API has a function for it (it's like searching in google map directly), which returns lat-lng coordinates, or a @not found@ error code, for the searched location. However, this comes at a cost... a lot of overhead.

For example, i was loading about 300 points on my map, all from locations. With the function to convert location through API, it might have taken about 30-40 seconds to load the map... but then i created a table a stored all the lat-lng coordinates in there, and loading directly from lat-lng took at most 2 seconds to load all 300.

i've implemented this before, and it's easy to use, but again, at a cost... see every time you call the function to convert, it makes a call to the google servers, and comes back... so... f.y.i.

Thanks for the suggestions.  I was hoping to find smoething other than the Google documents.  I prefer reading somebody elses blog/tutorial/article that has simplified the process and gives examples of what to do and what not to do.
