SQL

Hello,
I'm new for using Google APIs and is looking for a snippet which could help me out in using goggle visualization API. My motive is to add dynamic data instead of using data from spreadsheets. The API which I was using looks for getting data from remote could not explain this(ref : Setting the Query from JavaScript

https://developers.google.com/chart/interactive/docs/querylanguage#Setting_the_Query_in_the_Data_Source_URL).

I added a datasource url but it gives me an error as Microsoft JScript runtime error: google.visualization.Query: Not Found [404]. Please help me in getting remote data from my database instead of spreadsheets.
Thanks in advance.
