- crdb 10y agoGood catch. Too late to edit the comment. Yes, I meant C.J. Date's "Introduction to SQL". I was trying to get a link to the latest edition which appeared to be the 2nd link on an Amazon search for "Date introduction to SQL"... anyway, it is continuously edited so it's worth seeking the latest version which has twice as many pages as some of the earlier ones.
