I had to select a ton of records today for a project in ArcGIS. You know the normal method, hellish SQL repetition: ID = 1 OR ID = 5 OR ID = 6 OR ID = 12 OR ID = 14 OR ID = 27 OR ID = 41 OR ID = 43
The past few months I've been working a lot in SQL Server and this experience made this repetition seem like too much work. So I got lazy and I made an inquiry into IN query: ID IN (1,5,6,12,14,27,41,43)
And it just worked. There's no documentation in the main help file that even mentions it. If you do open the ArcGIS Help and search on "SQL Reference" nearly half way down you find a section on Subqueries. Here they explain that IN queries are supported in geodatabases and EXISTS is supported as well! Who knew? How was I supposed to know this if I hadn't gotten lazy?
Here's what you'll find in the ArcGIS Help File:
Remix IN with some external SQL that EXISTS here in ArcGIS One-to-Many Labeling and you might confuse ArcSDE for an RDMS. Just don't try look for anything meaningful in a RELATE.
I just did it again. We don't like to admit it, but we all have. You write a long letter describing the attachment, press send and then 10 seconds later remember you didn't actually attach the message. I finally decided to do something about it. Turns out it isn't too hard. Chiefly because Jimmy Peña at Code for Excel and Outlook already did all the hard work of writing up an excellent MS Outlook Etiquette Check Macro that does all the dirty work for you. What's left for you to do? In MS Outlook go to Tools > Macros > Visual Basic Editor Under the Project Panel (far left) Browse to Project1 > Microsoft Office Outlook Objects > ThisOutlookSession Double-click ThisOutlookSesson to Open (if you haven't been here before this will be a big blank canvas) Visit Code for Excel and Outlook Etiquette Check Code and select "Copy to Clipboard" at the top of the code. Or you can also copy from the code I've modified below if you prefer....
HTTP Redirect seems simple enough. Always was in IIS6 and in IIS7 there's even a button labeled HTTP Redirect that promises relative redirects. It looks like it'll be as easy Apache finally. That is until you try to redirect a querystring. Then everything bombs. Turns out it still is relatively easy, except you have to know that Microsoft changed $S$Q to $V$Q. Why? $Ss and $Gs I suspect. And How. In our example we'll redirect all pages under http://olddomain.com/content to http://mydomain.com/content. Pick the virtual directory you want to redirect. e.g. http://olddomain.com/content Click HTTP Redirect under IIS in the IIS management console. In the HTTP Redirect Dialog: Check Redirect requests to this destination Enter your new path ending with $V$Q. e.g. http://mydomain.com$V$Q Counter-intuitively check Redirect all request to exact destination (instead of relative destination) Choose the appropriate Status Code (Permanent or Temp...
ArcGIS is just plain lousy at dealing with any relationship that isn't one-to-one. We all have a slew of hacks just to deal with this limitation. I for one regularly am creating temporary cross-tab queries so I can represent multiple sample results at a collection point, fish surveyed at a cross-section and a host of other relationships. The classic example for mapping comes from the cadastral community and condominium lots. It's an odd situation where more than one person has title to the same piece of ground. How do you represent this? I've got a new trick thanks to Mohammed Hoque's article in ArcUser Magazine. We're going to do a database query inside a label expression, loop through the results and output the entire list to label. For our example we'll use Outfitting Areas in Idaho and we'll label them with the Outfitters and Guide License Numbers and Outfitter Names. 1.) Open ArcGIS and add your spatial layer with the unique identifier shared with...
