CREATE TABLE people (name VARCHAR(30), age INTEGER, height FLOAT, date DATETIME)
As you can see, the command "CREATE TABLE" does exactly that, creates a table which we have called "people". Then inside the ( brackets ) we tell it what columns to make. The first is called "name" and is VARCAR, the 30 indicates we are allowing up to 30 characters. The second, "age" is an INTEGER, the third "height" is a FLOAT and the forth "date" is DATETIME.
Regardless of which method you chose, if you would like to see a breakdown of what you just did click on the "people" link that now appears on the left hand side of your screen. On the right you should now see the fields you added, their data types, and other information.
