An invaluable SQL reference,
Rezension bezieht sich auf: Lan Times Guide to SQL (LAN Times series) (Taschenbuch)
This is a great book to begin to understand how to write queries for databases in SQL. It starts off with the simple queries, and moves onto the more advanced commands that are used for maintaining databases.
It is a simple and clear text, and has been an invaluable source whilst creating databases and writing code to interact with these databases.
