problem with sql interpreter

Hi, I have been taking the sql course and am having problem with page 5 from the 1st course. I cannot get the interpreter to insert any values into the table I created in page 4. After checking 100 times, I copy pasted the code from the "answers to questions" part for page 4 and 5, only changing the name of the table. Again the interpreter said "command executed" and nothing was there. Can anyone shed some light on this dilemma?

Thanks :confused:

Which sql couse? On which rdbms?

would you please point us to the right link and the also post all the SQL queries that you used?

Thanks so much guys, but I figured out my problem. When I make changes to charts, the program does not automatically show them like I expected. I have to enter select.

Thanks again :)
