SecuriTeam has an old, but still very useful article on SQL injection.
I’ve created a PDF of that article, containing some of the comments (all the ‘thank-you’ and ‘help-me-hack’ comments were removed): sql injection walkthrough pdf download.
Note: there were no specific license terms attached to the article; I believe that the word “free” on the SecuriTeam site logo refers to the “right of free use and copying”. If you know this is not the case – please let me know to remove this PDF from public access. (see Brian’s comment)
