What databases are supported by default?

The JUDO runtime core provides built-in support for HSQLDB (for development) and PostgreSQL (for production).

What is a JUDO RDBMS Dialect?

A Dialect is an interface in the JUDO framework that acts as a bridge, translating generic DAO operations into database-specific SQL syntax and behavior.

Can I handle database-specific types like JSON?

Yes, by overriding the RdbmsParameterMapper, you can define custom logic to map specific database column types to Java SQL Types.

How do I register a new dialect in my application?

You must implement the Dialect interface, create a Dialect Provider, and then bind that provider within a Guice AbstractModule to make it available to the runtime.

How do I execute database-specific initialization commands?

Implement the RdbmsInit interface to execute setup logic, such as setting session variables or creating custom functions, during the data source connection phase.

Extends the JUDO DAO framework to support new database dialects like MySQL, Oracle, and custom RDBMS systems.

关于

The JUDO RDBMS Dialect Extension skill equips Claude with the technical patterns and architectural knowledge needed to integrate new databases into the JUDO runtime. It provides step-by-step guidance on implementing the Dialect interface, configuring Guice modules for dependency injection, and handling database-specific nuances such as custom SQL type mappings and syntax variations for limits or offsets. This skill is essential for developers who need to move beyond standard PostgreSQL or HSQLDB support to implement specialized database logic or migrate JUDO applications to different relational database environments.
