Preface
The Java
programming language is now recognized as a major
player in the enterprise computing landscape, and has been embraced
whole-heartedly by Oracle Corporation, the world's leading
database developer. SQLJ is an exciting technology that enables your
Java programs to access a database. SQLJ allows you to embed
Structured Query Language (SQL)—the standard language used to
access databases—statements into your Java programs. You may
already be familiar with the Java Database Connectivity (JDBC) API,
another technology for adding SQL statements to a Java program. SQLJ
has a number of advantages over JDBC:
SQLJ is at a higher level of abstraction and has a simpler, more concise syntax than JDBC.
SQLJ is strongly typed, and checks your embedded SQL statements for correctness, unlike JDBC.
With SQLJ, the compiler does more of the work for you because it checks your embedded SQL statements during compilation. JDBC, on the other hand, checks your SQL statements only when you actually run your program. Checking your statements up-front is a lot more desirable than checking them at runtime, and should result in your programs taking less time to develop.
You may also be familiar with Oracle's Pro*C product, which enables you to embed SQL statements in C programs. Embedding SQL statements using SQLJ is similar in concept to Pro*C.
You can add SQLJ statements to many types of ...
