Eric, We'll take a look at using this one.
Thanks for the tip.

I don't recall who provided the tip, however, but it works and cuts down on superfluous code. -E ________________________________ From: Action Request System discussion list(ARSList) [mailto:arsl...@arslist.org] On Behalf Of Shellman, David Sent: Friday, August 06, 2010 10:17 AM To: arslist@ARSLIST.ORG Subject: Re: EXTERNAL Keyword ** One needs to be careful using something like 1=0. As others have noted this can cause a full table scan. On one of our forms we had 5 table fields that used the External function so that we could trigger when the tables displayed data or did not. There were Active Links that set fields to 1=0 for the use of External with the Table fields. We were seeing delays with displaying a record when the system was being used heavily. Some times, these delays were fairly lengthy. Recently I changed these Active Links to use a more realistic search against an indexed field. I replaced with some thing like 'Ticket ID' = "0". After the change the delays with displaying a record have virtually disappeared.

I believe there was some discussion earlier in the week about the (1=2) submitting a wiry to the db. For your table problem, What i have done is for any of my forms that use the external(), I have an active link that fires on open window and does a set field of "(1=2)". We do this for all table fields where required. We use this a lot in our system, for both the UserTool and mid-tier and have seen no issues or performance problems. Brent...

Then when the time is right replace that with your real search. You could use 1=2. I just tried it out on a test form. I also logged it client-side and it looks like it is going to query the db (maybe it is late enough on Friday where most people are not looking at the List and the 1=2 reference won't start a riot :) ************************************ Fri Jul 30 2010 15:50:30.5980 */SELECT TOP 1001 T773.C1,C536870915,C536870964,C536870965,C536871324 FROM T773 WHERE (1 = 2) ORDER BY C536870915 ASC, 1 ASC Jason On Fri, Jul 30, 2010 at 12:07 PM, Kemes, Lisa <<mailto:lisa.ke...@tycoelectronics.com>lisa.ke...@tycoelectronics.com<mailto:lisa.ke...@tycoelectronics.com>> wrote: ** I have a table that gets populated by a field that I build my query/search on.

If there is nothing in this field and someone clicks on the table, then ALL the data on that form gets pulled into that table! I was hoping that if nothing is in my query-search field then nothing would be populated into that table. :( Lisa Kemes AR System Developer Tyco Electronics 717-810-2408 tel 717-602-9460 cell <mailto:lisa.ke...@te.com>lisa.ke...@te.com<mailto:lisa.ke...@te.com> _attend WWRUG10 <http://www.wwrug.com> www.wwrug.com<http://www.wwrug.com> ARSlist: "Where the Answers Are"_ _attend WWRUG10 www.wwrug.com<http://www.wwrug.com> ARSlist: "Where the Answers Are"_ _attend WWRUG10 www.wwrug.com ARSlist: "Where the Answers Are"_ _attend WWRUG10 www.wwrug.com ARSlist: "Where the Answers Are"_ _attend WWRUG10 www.wwrug.com ARSlist: "Where the Answers Are"_ _______________________________________________________________________________ UNSUBSCRIBE or access ARSlist Archives at www.arslist.org attend wwrug10 www.wwrug.com ARSlist: "Where the Answers Are"
