Working with Derby SQLExceptions in an application

JDBC generates exceptions of the type java.sql.SQLException. If your application runs on JDK 1.6 or higher, the exceptions will be the refined subtypes of java.sql.SQLException introduced by JDBC4. To see the exceptions generated by Derby, retrieve and process the SQLExceptions in a catch block.

• Information provided in SQL Exceptions
  Derby provides the message, SQLState values, and error codes in SQL exceptions.
