Reading Data from Databases with SQL: Limit and Offset

I am having some trouble understanding limit and offset in the database foundations. I understand it in the examples they give in the video, but in the code challenge it tells me to "Get the 101st to 200th actor from the actors table." I am having trouble processing how to make this work. Could anyone explain and clear this up for me? Thanks!

I'm having trouble with this challenge also. This is what I tried..... "SELECT * FORM actors LIMIT 99, 200;" Can't seem to figure this one out.

One way may be where id > 100 limit 99

"id" is incorrect because there's no column for it. I tried "SELECT * FROM actors WHERE name > 100 LIMIT 99;" This did not work either. Please someone help with this challenge.

Hi Dennis Howell, I see that my original comment may have steered you wrong. This code challenge would like you to use the LIMIT and OFFSET options. The LIMIT option determines how many records to pull and the OFFSET option selects the starting number plus one. Therefore, if you want the first 100 records starting at the 101st record you'd use: 

SELECT * FROM actors WHERE LIMIT 100 OFFSET 100

Hope that helps!
