Java sample application: Automating update
In this section we provide a Java application that can determine the difference
between two database configurations, generate the required DDL and SQL
statements for altering a table, and finally execute the statements. We look at the
same scenario as shown in Figure 5-4 on page 245, that is, we have some
changes in the itso.staff table in our sample database. The application is intended
to be used on the target system with no access to the source system at runtime.
Therefore, the application is shipped with the configuration of the source
database. Once started, the application connects to the target database and
retrieves the configuration by querying the DB2 metadata.
