Jumped into PL/SQL stored procedures today, with the "help" of the O'Reilly book Learning Oracle PL/SQL. Turns out the place I started in on the material had no less than ten errors in just more than as many pages (152-165). Nice stuff there. Made it a bit more difficult to learn my PL/SQL (or, as I like to call it, pluhskwill). Guess that's what you get for $10.59. (To the book's credit, there are only 12 errors in the rest of the 401 pg book, at least errors listed on its errata page. But wouldn't you know I'd hit the motherlode right off the bat...)
