RE: select next/previous *record*?
Don't you need to know something else if you use Last Name as the index? What if there are multiple John Smith's? I haven't actually done this, but what if you pulled all records with the last name they selected, then used array notation to pull the ID from the record before and after the current record? Too bad databases don't generally have a numeric, sequential record number like ColdFusion's query object (currentRow variable). -Original Message- From: Matt Robertson [mailto:[EMAIL PROTECTED] Sent: Sunday, December 12, 2004 1:41 PM To: CF-Talk Subject: Re: select next/previous *record*? Quick question...are ya using DreamweaverMX? Nope. Another complication I didn't mentuion before is the user has the ability to select which index is current, so they might be indexing on ID, and cycling up and down thru the numbers, or one of several other fields, such as Last Name. I'm working thru that now. Don't see how it would work in the ID-based example. -- --Matt Robertson-- President, Janitor MSB Designs, Inc. mysecretbase.com ~| Special thanks to the CF Community Suite Silver Sponsor - New Atlanta http://www.newatlanta.com Message: http://www.houseoffusion.com/lists.cfm/link=i:4:187409 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4 Donations Support: http://www.houseoffusion.com/tiny.cfm/54
Re: select next/previous *record*?
Yes, I was thinking along the same lines, but I can't think of a way to do it that would be even remotely efficient across about 10 key fields they want to page thru display on. I may revisit the issue when I have some more time but these guys have signed off on foregoing this feature for now. -- --Matt Robertson-- President, Janitor MSB Designs, Inc. mysecretbase.com ~| Special thanks to the CF Community Suite Gold Sponsor - CFHosting.net http://www.cfhosting.net Message: http://www.houseoffusion.com/lists.cfm/link=i:4:187460 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations Support: http://www.houseoffusion.com/tiny.cfm/54
Re: select next/previous *record*?
I have an application where the user selects a record via a key lookup, and then that record is displayed individually. From there I want to be able to click a '' button to go to the previous record in the sequence, or a '' to go to the next record, and continue to select records via this method as an alternative to the key lookup. I did this in an entirely different environment where I was able to use native controls that allowed straight up SELECT NEXT and SELECT PREVIOUS commands, where I was also able to throw those commands into a loop for fast forward and rewind as well. Don't expect to get that in the web world, but I need the next/previous. I think I can come up with something, but the convolutions necessary to make it work are making my head hurt. Is there something simple and obvious I have missed on this (for me) Sunday morning?.

Re: select next/previous *record*?
Thanks Barney, thats *exactly* what I was looking for! -- --Matt Robertson-- President, Janitor MSB Designs, Inc. mysecretbase.com On Sun, 12 Dec 2004 11:12:27 -0800, Barney Boisvert [EMAIL PROTECTED] wrote: I'm not sure exactly what you're looking for, but if it's SQL, I've done this in the past: SELECT * FROM table WHERE id #currentId# ORDER BY id DESC LIMIT 1 for getting the previous item. Just flipt the to and make the order ASC to get next record. The LIMIT clause is MySQL's version of MS products' TOP clause. If you want to fast forward, the LIMIT clause also specifies an offset, so you can do LIMIT 19, 1 to pull the 20th item in the list. With MS's TOP clause, you have to pull all 20, and then just look at the last one, I believe. cheers, barneyb On Sun, 12 Dec 2004 10:58:50 -0800, Matt Robertson [EMAIL PROTECTED] wrote: I have an application where the user selects a record via a key lookup, and then that record is displayed individually.
