Headline

Database programming with JDBC and H2-Database containing one or more companies and using SQL Sum

Characteristics

We use JDBC/SQL for data processing. That is, we use embedded SQL in Java.

Illustration

This contribtuion is using the "SUM" statement:

SELECT SUM(salary) FROM employee

SUM adds all salaries, there is no need for a loop for adding the single salaries like in h2jdbcMany.

Relationships

For a MySQL version see Contribution:mySqlMany.

For a version not using SQL "Sum" statement see Contribution:h2jdbcMany.

Usage

This contribution uses Technology:Gradle for building. Technology:Eclipse is supported.
