ODTUG Kaleidoscope 2010: Best Practices

Updated: 29-Jun-2010, 30-Jun-2010.

For me, ODTUG Kaleidoscope 2010 started on Friday with the ACE Directors briefing. Best practices topic was touched there slightly and I twitted about it. I decided that the feedback deserves a blog post so I’m simply quoting the conversation here. If you have anything to add, you know where to find the comment box.

alexgorbachev:
best practices should be forbidden or rather renamed to blue-prints #ACED

MySQL’s SQL Deviations and Extensions

Today at Kaleidoscope I will be doing a 90-minute session comparing MySQL’s SQL syntax to the ANSI/ISO SQL:2003 standard, entitled What Do You Mean, “SQL Syntax Error”?

You can download the PDF slides now.

For those that may be following along the presentation later today (4 pm Eastern time), here are some links that I may throw out during the session:

  • SQL 2003 standard – actually it is “Information taken from the Final Committee Draft (FCD) of ISO/IEC 9075-2:2003″ but it’s extremely close to the actual standard. The actual standard is a document that costs a non-trivial amount of money to get, and cannot be republished.

MySQL and Quoting

MySQL does not follow the ANSI SQL standard for quoting. MySQL’s default quoting behavior is that either single or double quotes can be used to quote a string (this gets me into trouble when I work with Oracle databases, as double quotes do not indicate a string!).

mysql> SELECT 'alive';
+-------+
| alive |
+-------+
| alive |
+-------+
1 row in set (0.00 sec)

mysql> SELECT "alive";
+-------+
| alive |
+-------+
| alive |
+-------+
1 row in set (0.00 sec)

Bare words are dealt with in context; in this case, a bare word would be parsed as a column name:

mysql> SELECT alive;
ERROR 1054 (42S22): Unknown column 'alive' in 'field list'

Backquotes are the way MySQL escapes table names. So, if you want a reserved word, number or operator to be the name of an object (ie, a table named “1″ or a column named “date”) you need to use backquotes to avoid a syntax error….for example:

mysql> …

Log Buffer #192, A Carnival of The Vanities for DBAs

It’s Friday, and summer’s here. While it seems the industry is slowing down to a lazy pace, there is still some action so let’s splash right in to this week’s edition of Log Buffer DBA industry news in Log Buffer #192.

Alex Gorbachev had a few minutes to suggest the following interesting tidbits to me before running off to attend Oracle ACE Director activities at ODTUG/Kaleidoscope this weekend. One of these days we’ll have to see if he can share some of what goes on behind closed doors at those hush …

ODTUG Kaleidoscope 2010 — Ready… Set… Go-o-o!

It is time… Time for one more very special conference for me. Why special?

  1. I have never been to ODTUG Kaleidoscope before. I always like new conferences — new experience.
  2. Unlike Sheeri, I do not speak! This is one of those rare conferences where I come to slack off, meet old friends and make new ones, go to lots of sessions and actually learn stuff.
  3. Coming from the DBA background, it’s not often that I come to development oriented conferences and I think I should do more of that.
  4. It’s in Washington, DC. I lived there for some time and have number of good friends there. I’m really excited to see them again!

So what am I going to do there? I just arrived and right in time for the Oracle ACE Directors’ briefing that will run for the whole days of …

Next Week’s MySQL Sessions at ODTUG Kaleidoscope

By now you know that there is a MySQL Track during next week’s ODTUG Kaleidoscope in Washington, DC. Ronald Bradford and I organized the schedule at the last minute (Ronald did a lot of the work!). It was difficult to fill a schedule with 19 sessions that are either 1 hour or 1.5 hours long, and to do it I ended up with three presentations.

At each presentation I will be giving away a copy of The MySQL Administrator’s Bible, so be sure to show up! All MySQL track sessions are in Maryland C, and all times are Eastern.

On Monday, June 28th from 4 pm – 5:30 pm I will be presenting …

MySQL Sunday tracks at Oracle Open World 2010

Oracle Open World is the conference of everything related to Oracle. This year edition, running from September 19th to 23rd, is expected to have more than 45,000 attendees, making it one of the biggest IT events worldwide.

Traditionally, on the Sunday preceding the main event, there is a full day technical event, fueled by the user groups, independently from the company. These Sunday events are wildly popular. they are organized by users for users, and these sessions are usually fully attended.

Now that MySQL is part of the Oracle portfolio, it is going to be part of the Oracle Open World show. In the spirit of the user groups events, there will be a MySQL Sunday event on Sunday afternoon, with four highly technical tracks, with well known speakers. …

Keeping Up

I found I never published this post as it was sitting in my drafts few months now — it was written in 13th February, 2010. I’m publishing it without any changes.

I learn therefore I am!

I’ve just wrote few bits about learning a new technology and after skimming through my Google Reader, I noticed a great post by Chen Shapira — Deliberate Practice. That’s reminded me about another aspect of learning that I didn’t mention — learning is a continuous process.

There are two aspects…

  • No matter how good I am and how much I know, my knowledge and expertize become outdated relatively quickly these days unless I keep up with the new stuff. Unfortunately, there is so much new …

#ODTUG Kaleidoscope 2010 Odds and Ends

Several things to think about in the next 10 days leading up to Kaleidoscope.

1. The Marriott Wardman Park is out of rooms. If you’re attending and haven’t reserved a room yet, you may get lucky with a cancellation, but there are several hotels on the Metro line that should have openings. The conference and location is very popular, and while I wish we could accommodate everyone, it’s not going to be possible. Here’s a good suggestion: when next year’s conference dates and location are announced, register and reserve your room as soon as possible (hint – these announcements will be made at our general session on Monday, June 28 starting at 8:30 AM).

2. The Java Bus is coming! Monday afternoon/evening, June 28, the Java “Code to …
