Whenever I Google this it brings up pages related to Database management. However, I want to run this in the actual webpage.

For example:

You go to a webpage where you can practice SQL:

I.e. you have a window where you type:

Create table  T1 (
   Id not null,
   Name varchar(60)
);

Insert in T1 (Id, Name) 
values (1, 'john');

Select * from T1;

This would give you a single row, two column table
Where the I’d is 1 and the name is John
Id | Name
1 | john

Thanks!
