Java Connectivity with Dataverse 

The driver supports two main authentication methods: Active Directory (On-Premises) for on-premise deployments and OAuth for both online and on-premises instances. OAuth options include Authorization Code, Client Credentials, Certificate, and Password authentication.

The driver includes a connection management utility. By running the command java -jar kingswaysoft.jdbc.jar, you can enter your credentials and server URL, and the program will automatically generate the correct JDBC connection string for your application.

You can execute standard SQL statements such as SELECT, INSERT, UPDATE, and DELETE using Statement or PreparedStatement in your Java code. The driver handles translation of these SQL commands to the Dataverse Web API.

The UPSERT operation combines INSERT and UPDATE functionalities into a single command. It checks for an existing record based on a specified key. If the record is found, it is updated; if not, a new record is created. This is useful for data synchronization and preventing duplicates. You can use Alternate Keys or manually specified keys for matching.

Using a PreparedStatement is recommended for improved performance and security. It allows the driver to precompile SQL queries, making repeated executions more efficient, and protects against SQL injection by processing parameters separately from the SQL command text.

Yes, the driver supports various query options to fine‑tune operations. You can append USING OPTIONS(...) to your SQL statement to enable features like BypassCustomSyncBusinessLogicExecution to disable synchronous plug-ins or EnableSystemDuplicateDetection to enable duplicate checking.
