Earlier this month, I conducted a totally unscientific survey on Twitter, asking where people got their Oracle news from.

“What do you mean there’s line breaks in the address?” said SQLLDR

SQL vs. Excel – Subgroup medians
Got anyone who needs April Fooling?
Do you have a sql*plus user who really needs an April Fool’s joke played on them? With a little editing to their glogin.sql, every sql*plus session will exit with what appears to be a pseudo-random TNS error.
Review: Oracle RAC Performance Tuning
Some time ago, I received a free review copy of Brian Peasland‘s recent book, Oracle RAC Performance Tuning.
Roman numerals to decimal in SQL
Earlier this week I got tangled up doing a Roman Numeral conversion in my head. So of course my second thought, right after “Doh!”, was “I bet I can write a SQL statement to do this for me next time.”
Search plugins: Search Oracle docs from your browser search bar
Tired of navigating to the SQL documentation every time you need to look up syntax? I created a search plugin so that you can search the SQL documentation directly from your browser’s search bar:
