Hi all, I guess now I am at the different end, after having replied to many requests for info on books. I do not have access ( ha-ha) to a library, though I do have access to a bookstore. I am looking for an intermediate-to-advanced book in Database. I have covered the basics: Normalization, QBE's, some intro SQL queries in Access : update, select from , count/avg/sum ( aggregates), etc. Integrity Constraints, Indexes, ERDs (Entity-Relation Diagrams) using Microsoft Vicio. Now looking at the next level, which, from what I found involves triggers, more advanced queries (e.g., find the n-th highest salary ). Any suggestions for a book? Thanks.
