I have become so accustomed to have SIDs configured in tnsnames.ora - never having to remember anything.
After migrating to a new laptop yesterday, I lost all my connection information (doh!) and have had to resort back to the SQL Plus connect string. How beautiful it is:
sqlplus user/password@//10.10.10.10:1521/sid
syber:- uber geek chic .. clogging the tubes with personal prattle, random music likes, technical segues, and rants since '05.

select random
And they call SQL a "standard" ;)
Select a random row with MySQL:
SELECT column FROM table
ORDER BY RAND()
LIMIT 1
Select a random row with PostgreSQL:
SELECT column FROM table
ORDER BY RANDOM()
LIMIT 1
Select a random row with Microsoft SQL Server:
SELECT TOP 1 column FROM table
ORDER BY NEWID()
Select a random row with IBM DB2
SELECT column FROM table
ORDER BY RAND()
FETCH FIRST 1 ROWS ONLY
Select a random record with Oracle:
SELECT column FROM
( SELECT column FROM table
ORDER BY dbms_random.value )
WHERE rownum = 1
Note. I'm not complaining too seriously, in my work I mostly use Oracle (occasionally DB/2 but that can't be helped). I am aware of the wealth of functionality available at Oracle over say, MySQl, which mostly excuses the differing syntax.
