For example:

You go to my a page where you can practice SQL

So you enter a page and you have a window where you write

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!
