If you are a fan of the Oracle database, then it is impossible not to have heard about the ROWID pseudo-column. However, as a quick reminder, the ROWID pseudo-column is associated with each row by Oracle, and its main goal is to return the address of the row.

For instance, the following statement inserts a new SALE and fetches the generated primary key and the ROWID:

ctx.insertInto(SALE, SALE.FISCAL_YEAR, SALE.SALE_, 
               SALE.EMPLOYEE_NUMBER, SALE.FISCAL_MONTH, 
               SALE.REVENUE_GROWTH)
   .values(2004, 2311.42, 1370L, 1, 0.0)

   .fetchOne();

Ever wonder why speech recognition systems don't understand the Scottish accent, or what would happen if an astronaut only ate mac 'n' cheese, or other spurious reflections you'd have at a bar? We did, then collated those deliberations into absurd research articles with fake figures and methodologies inspired by even more fictionally absurd studies.
