This section provides a walk-through of writing data access code to Azure Cosmos DB in JDBC.
Connecting from Code
See Establishing a Connection for the prerequisite information you need to deploy the driver and configure the connection to Azure Cosmos DB. Connecting from Code shows how to connect with the DriverManager or CosmosDBDataSource classes.
Use the Statement and PreparedStatement classes to execute SQL to Azure Cosmos DB:
- See Executing Statements to execute Statements and iterate over the returned ResultSets.
- See Using Prepared Statements to execute parameterized statements. The PreparedStatement class provides a means to efficiently execute queries more than once and to mitigate SQL injection attacks.
See Batch Processing to take advantage of the Azure Cosmos DB bulk processing functionality. The driver converts the JDBC batch commands into a single request to Azure Cosmos DB.
Executing Stored Procedures
You can execute stored procedures as parameterized statements (with the CallableStatement class) or SQL statements (with the EXECUTE syntax): see Calling Stored Procedures.
Instantiate pooled connections with CosmosDBDataSource objects: see Connection Pooling to create and configure the pool.
