168. JDBC Programming
Version 6.0.1

Book cover

This one-day course covers the fundamentals of database programming in Java using JDBC (Java Database connectivity) in an incremental fashion, to get the programmer up to speed quickly and then to layer a deeper understanding of JDBC upon that foundation. This course has been designed to work with any of these relational database management systems:

  • Apache Derby 10.6
  • Oracle, version 9i, 10g, or 11g

Lab exercises use SQL99 constructs whenever possible in order to be relevant to databases from all vendors.

This revision of the course targets Java 6. For training targeted to earlier Java environments, please see version 4.5.1 and version 5.0 of this course; to read more about different versions of Java and for help deciding on which version of this course to use, see "Java Versions and Terminology Demystified".

Prerequisites

  • Experience in Java Programming is essential. The student must be comfortable with object-oriented Java, interfaces and abstract classes. Course 103, "Java Programming," is excellent preparation.
  • Understanding of basic SQL usage or other work with relational databases will be helpful, but is not required.

Learning Objectives

  • Briefly review relational database fundamentals with an awareness of the differences between SQL99 and SQL implementations by database vendors.
  • Connect to a database using JDBC and perform a simple query.
  • Update relational data using JDBC to execute updates, inserts and deletes.
  • Use prepared statements to produce reusable database queries and optimize execution time.
  • Use callable statements to access database procedures.
  • Use scrollable and updatable results sets for more robust solutions.
  • Use commit, rollback, and savepoint to build transactional systems.
  • Use batch processing for efficient handling of large datasets.
  • Understand the use of RowSets and the improved techniques and portability that they bring to JDBC.

Timeline: 1 day.

IDE Support: Eclipse Helios

  • In addition to the primary lab files, an optional overlay is available that adds support for Eclipse Helios. Students can code and build all exercises from within the IDE. See also our orientation to Using Capstone's Eclipse Overlays.
