Hot on the heels of the Linux 64-bit release, Oracle 11g for Windows (32-bit only for now) is now available for download on OTN.
It looks like the second public platform release for Oracle 11g is (surprise, surprise) Linux x86-64. Downloads are available on OTN.
Dave has been sick these past two days and as a result, we do not have a comprehensive log buffer ready. I had two choices – cancel this week’s log buffer, or try to make it great despite this adversity. Never one to accept defeat easily, I’ll go for the second option. So this week’s log buffer is as follows: we are counting on each and every one of you, our faithful readers, to propose the one article you read in the last week, and include a short paragraph as to why this article was interesting to you and why it should interest us.
Welcome to the 66th edition of Log Buffer, the weekly review of database blogs, raking up the blogs like so many fallen leaves.
If you are or have ever been a SQL developer, it’s very likely you’ve been asked to return the rows from two joined tables, including all the rows from both tables that do not have a corresponding row in the other table. Oracle 9i introduced the FULL OUTER JOIN syntax to better address this scenario. Now it looks as if 11g has introduced a new algorithm to handle that. So how can you get a look at this? Find out here.
I was very pleased when I heard about Oracle adding pivot functionality in select statements. Finally — we wouldn’t have to copy the data to a spreadsheet or code a ton of sum(case when col1 = ‘X’ then amount else 0 end) total_X for each column we would want to display. I am basically looking for three things in a pivot-style query: the ability to specify which column will be pivoted as one or more columns in the resulting query, row subtotals, and column subtotals. The first item is the only one that really matters. I can work around the other two, so let’s get started.
As promised in my earlier SIOUG post, here are the delegates of the The Pythian Group at the Slovenian Oracle Users Group Conference (SIOUG):
Frank Wiles has published the 65th edition of Log Buffer the weekly review of database blogs, on the Revolution Systems Blog. For the record Frank published it right on time on Friday – it’s just us that’s late. Sorry about that.
It seems Oracle 11g introduces a difference between count(*) and count(1). The way this happens is just the opposite of what I was thinking would happen. NB: I ran my test using “220.127.116.11 32bits” on Ubuntu Linux 7.04 (Feisty) which is not officially supported1, and which has already lead me to some unexpected behaviors. If this difference with count() is really the 11g way and not buggy behavior related to the Ubuntu install, I’m glad to have found it. Here’s what you can do to observe (or confirm or dispute) this.
First on the schedule of the second evening (28th of September) was the Gala Diner. Mr. Nogood opened it and marked Oracle ACEs, OCP/Ms and Oak Table Network members with special distinction — a blue silk sash. Sadly, I can’t find mine in my travel bag; I think perhaps the Water-Park has it now.
