We enjoyed bringing you "That Podcast" - and soon, we'll be doing another podcast: Thu'umcast: A Skyrim Gameplay Diary. We'll have an iTunes feed, and a Facebook group, probably a Google + setup as well. Stay tuned - once the game launches, we'll start recording!

Today we'll look at setting (and unsetting) an error handler for database exceptions. In some cases, you may not want to catch all possible errors at the place they originate; you'll want a catchall handler specific to database issues. That turns out to be easy to set up in VA Smalltalk:
"set up an error handler for db work"
AbtDbmSystem activeDatabaseMgr errorBlock:
[:error | Transcript show: 'Whoops, that did not work out for us: ', error errorText printString; cr].
To illustrate, let's execute a query that won't work:
"try a query that should throw an error"
resultCollection := OrderedCollection new.
querySpec := (AbtQuerySpec new)
statement: 'SELECT EMAIL FROM PEOPLE'.
result := connection resultTableFromQuerySpec: querySpec.
result do: [:eachRow | resultCollection add: (eachRow)].
^resultCollection.
Instead of an error notifier, you get a message in the Transcript:
This can be useful when you are running a server system, and don't want a default notifier to pop up. Instead, you can log the error, and then have the system do something intelligent - quit, reset connections, whatever. If you want to reset to the default handling (for development, probably), just execute the same code with a nil argument:
"reset to default handling"
AbtDbmSystem activeDatabaseMgr errorBlock: nil.
Now you'll see the default handling when you try that bad query:

The website design is up - it's waiting for the launch of the game. We also have a Facebook group ready to go. If you liked "That Podcast", you'll probably like "Thu'umcast" :)

Today we'll look at checking the results from a query in VA Smalltalk, and then prompting the user on empty results. Let's do a query that should result in no answers:
"try a query that should return no rows"
resultCollection := OrderedCollection new.
querySpec := (AbtQuerySpec new)
statement: 'SELECT * FROM PEOPLE where ZIPCODE = 34567'.
result := connection resultTableFromQuerySpec: querySpec.
result do: [:eachRow | resultCollection add: (eachRow)].
resultCollection isEmpty
ifTrue: [CwMessagePrompter message: 'No Rows Came Back' title: 'No Rows'].
The checking is fairly obvious; we simply use standard collection protocol. Then we use the standard CWMessagePrompter class to pop up a warning dialog.
And that's about it for today

I think we need to see how Apple lets this play out before anyone panics. I also think there's a fairly large market for people who want to treat their computer like an appliance that doesn't need ongoing maintenance....
Believe it or not, SCO isn't dead yet. SCO Group, by its lawyers Boies Schiller & Flexner and Hatch & Dodge, has just asked the US District Court for the District of Utah to reopen [PDF] its litigation against IBM
IP law is getting to the point where it's impossible to parody....

Welcome to episode 0 of "Thu'umcast" - a podcast where Michael Lucas-Smith, Scott Dirk, Austin healy, Makahlua and I document our trials and tribulations in Elder Scrolls V: Skyrim
Today we set the stage for Skyrim with a quiz on Elder Scrolls mythology - Michael asked the questions, and, other than Maki, the rest of us show how little we know :) We'll be getting into the gameplay proper once the game is released on November 11th, so stay tuned for that!
If you liked our work on That Podcast, you'll probably like this. We intend to stay with the same idea - a gameplay podcast. If you don't want spoilers, don't listen - we are going to be talking about how we play the game, and what we ran across as we played.

"That Podcast" is done, but never fear: the crew (expanded!) is back with Thu'umcast, a gameplay diary for Elder Scrolls V: Skyrim. This will be the last post into this feed; if you want to hear the rest of Thu'umcast, then subscribe to the new feed

Today we'll get started with GLORP for VA Smalltalk - for our examples, we'll be using the ODBC support and PostgreSQL, but it's going to be the same for any other database (such as DB2) at this level. To start with, let's load the support in from ENVY. Open up the load/unload features tool from the launcher:
Just hit "Ok", and let it spin - you'll have GLORP support loaded shortly.
Next time we'll start taking a real look at GLORP itself.
