When you travel as much as I do, you're bound to hit bad weather every so often - and tonight I hit the jackpot. A line of storms diverted us to Houston for fuel, and then a second line kept us circling DFW for a bit. Then I had to wait in a long line at Avis - I hadn't updated my card with them, so even though I was on the "Preferred" board, I had to go talk to them.
One of those days....
Today's Smalltalk 4 You looks at deleting rows from a database using VA Smalltalk. We'll look at the "object" level interface to that today, and get to general use of SQL in a future screencast.

Today we'll look at deleting data from a database using VA Smalltalk - to see how to connect, please go back to this tutorial, as we are building on it here. You can do this sort of thing directly via SQL, and we'll be getting to that in another screencast. Today we'll be looking at the "object" interface for this.
Once you have a connection to your database set up (with a user who has permissions to make changes), you can delete data pretty easily. First, query the data out of the database:
"delete a row" table := connection openTableNamed: 'PEOPLE'. querySpec := (AbtQuerySpec new) statement: 'SELECT * from PEOPLE where PEOPLE.ZIPCODE = 12345'; hostVarsShape: (nil). rowToDelete := (connection resultTableFromQuerySpec: querySpec) first. table deleteRow: rowToDelete.
Next, commit the work:
"commit it" connection commitUnitOfWorkNow, before we executed the delet, here's what we had from the query:
And here's what we had after the commit:
That pretty much wraps it up for today - we'll look at some more examples next time.

As the current generation grows up, it should be kind of amazing to watch the expectations they'll have about user experience:
Spotted in the Seaside mailing list, by Nick Ager:
I've just published an initial integration of JQuery Mobile [1] with Seaside. You can try it out at: http://jquerymobile.seasidehosting.st
It's nearly complete - the outstanding work is to integrate JQuery scripting support - though it's certainly usable in it's current form. Feedback is welcome.

From the mailing list announcement:
We have released the new version 1.7 of Fuel, a binary serialization framework for Pharo that provides extremely fast deserialization. More information on our home page. Again, I thank ESUG for sponsoring me through the SummerTalk program.
You can download this version in Pharo 1.2.1 or 1.3 with:
Gofer new squeaksource: 'Fuel'; package: 'ConfigurationOfFuel'; load. ((Smalltalk at: #ConfigurationOfFuel) project version: '1.7') load.
The STIC conference is shaping up for next March:
STIC is a forum where Smalltalk professionals, researchers, and enthusiasts can meet and share ideas and experiences. We are currently accepting proposals for talks involving Smalltalk technology and other areas of innovation in the software industry. We're looking forward to an excellent conference, and need your participation to maintain the high technical level of the conference!
The conference will take place in Biloxi, Mississippi, March 19 13 21, 2012.
Presentations will have 45 minutes time slots including discussion. They may be in the form of
- Technical Presentations
- Experience Reports
- Technology Demonstrations

We love them so much that they now outnumber us:
That's only going to rise - lots of people will end up with a phone, a tablet, and maybe a separate e-reader. This has implications for anyone who thinks we can "easily" reduce power usage as well...

Today we'll look at updating data in a database using VA Smalltalk - to see how to connect, please go back to this tutorial, as we are building on it here.
Once you have a connection to your database set up (with a user who has permissions to make changes), you can update data pretty easily. First, set up a querySpec for the data you plan to change.
First, let's execute a query to see what we have now:
resultCollection := OrderedCollection new. querySpec := AbtQuerySpec forEntireTable: table. result := connection resultTableFromQuerySpec: querySpec. result do: [:eachRow | resultCollection add: (eachRow)]. ^resultCollection first asDictionary
That gives us this, if we inspect the results:
Now let's create a query to grab the data, and change it:
querySpec := (AbtQuerySpec new) statement: 'SELECT * from PEOPLE where PEOPLE.ZIPCODE = 12345'; hostVarsShape: (nil).
Now we'll do the following steps:
oldRow := (connection resultTableFromQuerySpec: querySpec) first. newRow := (oldRow deepCopy) at: 'zipcode' put: 23456; yourself. table := (connection openTableNamed: 'PEOPLE') atRow: oldRow putRow: newRow; yourself. "commit it" connection commitUnitOfWork
Now we'll do the query again, to ensure that we have done the update:
That pretty much wraps it up for today - we'll look at some more examples next time.

Alan Knight took some time with the new language, and has some fairly detailed thoughts on it.
