It was Chen Shapira's idea and here I am making it the official first ever Oracle community contest.
Read on to learn more about the obfuscated SQL code contest.
What does obfuscate mean?
To obfuscate means to make so confused or opaque as to be difficult to perceive or understand.
What are the goals of the contest?
To write the most Obscure/Obfuscated SQL query.
To show the importance of SQL programming style, in an ironic way.
To stress SQL techniques with unusual code.
To illustrate some of the subtleties of the SQL language.
To provide a safe forum for poor SQL code.
What are the rules of the contest?
Your entry must be one SQL script file.
The SQL script must contain only one SQL (SELECT) statement.
The SQL statement can be as short or as long as you want and may contain an unlimited number of subqueries or inline views.
You must provide the database version the script was tested on.
The SQL statement must be able to be executed by anyone with a connection to an Oracle database - with at least the same database version as indicated by the author.
If needed, the script may include test data or database object creation code required to make the SQL statement execute successfully.
The SQL script must be of original work.
Who is eligible to participate?
Any Oracle Community member is eligible to submit one entry.
How do I submit an entry?
Just upload the SQL script file with your reply below. Make sure the file's extension is either sql or txt. In addition to uploading the file, you may also include a link to your entry, if you have published it on your blog or web site.
April 1st 2008 is the last day you can participate in this contest and submit your entry. After that date, all eligible entries will be voted/commented on. The author of the most popular entry will be declared the winner.
does it need to be our own code? I don't think I could win if I had to write something worse than other peoples code that I see everyday.
here's one from OTN. the question was "how to calculate the next YYYYIW in a sequence". but it really was "the next IYYYIW". so if you're currently in 200813, the answer is 200814. but at the end of a year, you wrap around to IYYY+1, and IW goes back to 01. and don't forget to account for years with 53 weeks (like 2009).
The Obfuscated sql statement makes use subquery factoring, generates rows from dual via "connect by level <", and is overall quite the spectacle to look at. and it is truely obfuscated when you consider the same results can be achieved with this simple statement:
well if I had that exact version, I'd try it ;)
so instead I tried just a little lower and just a little higher, and neither worked.
so how about someone with 10.1.0.5 try it and post the results so I can at least see what I'm missing.
and since this seems to work on one and only one subversion, it might be the most obfuscated code possible.
