PL/SQL is the Oracle Procedural Language extension of SQL. PL/SQL is integrated within the Oracle database. A PL/SQL program can have both SQL statements and procedural statements. In the program, the SQL statements are used to access sets of data stored in a database, while the procedural statements are used to process individual piece of data and control the program flow, by applying, for example, the PL/SQL's if-then-else and looping structures. This book, Oracle PL/SQL Programming Fundamentals By Examples, is for PL/SQL beginners. If you have no prior or limited skill of PL/SQL, and you...

This book, IBM DB2 SQL for Beginners, is for you if you want to learn SQL in the IBM DB2 database the easy way. SQL (Structured Query Language) is the standard language you use to interact with a relational database management system (RDBMS). This book uses the free edition of the IBM DB2 database called Express-C Edition to show how SQL works in DB2.

This book is your first step to learning PL/SQL in IBM DB2. Yes, it is PL/SQL in IBM DB2 PL/SQL used to be an exclusive database procedural language to the Oracle database, now is available in IBM DB2.

This book is for you if you want to learn Oracle stored programs the easy way. By particularly following the book examples you will quickly gain practical skills. You write a stored program in PL/SQL. When you successfully compile the PL/SQL source code, the resulting program, which is a database object, is stored in the database (hence the name stored program). Other programs and other users that have the permission can then use the stored program.

This introduction to SQL for the Oracle database begins by discussing exactly how data is stored and maintained in a relational database, familiarizing readers with SQL INSERT, UPDATE, and DELETE statements. The guide then discusses how to construct basic queries, choose an appropriate output, and how to create and use groups. Readers will also learn how to use joins to query data from multiple tables, how to create predefined views that can be stored in a database, and how to utilize the metadata of a database. Appendices round out the book, covering the various indexing techniques available...

The book title implies that SQL Queries for R Users is for R users who need to get the data they need from a database. Loading large raw data from a database into R workspace is often unnecessary or even prohibitive. The book teaches you how to write SQL queries to retrieve precisely only the data needed from an SQL database. But, this book covers topics on metadata, which is equally important if not more than the SQL queries. To write an SQL query you must first know where the data is, the name of the tables and columns, their relationships, and the characteristics of the data. The book...
