SQL and PLSQL Simplified  (English, Paperback, Tajammul Abdul Quadeer)

Whether you are new to SQL or trying to brush-up your SQL Commands, this book is organized to take you through the journey of SQL Command Language followed by a working examples through the command line interface. I firmly believe that the best way of learning is by typing the command and seeing the output yourself. This will not only re-enforce your understanding of the command, but will make the concept very clear. SQL was created by IBM way back in 1970, so even with 52 years of age, and with the advent of many programming languages, SQL continues to remain popular with the student community and the programmers working with databases.
