selecting items that come after a specific value
Say this is my sql:
SELECT title,
author,
ISBN
FROM bs_books
ORDER BY ISBN
LIMIT 3
It just selects everything from a certain table (title, author, etc..).
Say I would like to开发者_JS百科 select all the items that come after a certain title, not alphabetically or something but just the records after the certain element. How would I approach this?
Find the ISBN for the title you want following-ISBNs for, then simply:
SELECT title, author, ISBN
FROM bs_books
WHERE ISBN>'978-3-16-148410-0' -- or whatever ISBN
ORDER BY ISBN
LIMIT 3
If you want to select it from just the title in one go, you could use a self-join:
SELECT b1.title, b1.author, b1.ISBN
FROM bs_books AS b0
JOIN bs_books AS b1 ON b1.ISBN>b0.ISDN
WHERE b0.title='Title for which to get following ISBNs'
ORDER BY b1.ISBN
LIMIT 3
You can use OFFSET somenumber
to start at a given numeric position. Maybe that's also ok for you?
If there is a primary key with auto-increment, you can do something like WHERE pk>=somenumber
.
