Enterprise-class JDBC Connectivity
The HPCC JDBC Driver offers the most natural way to access HPCC data from any
Java/J2EE application. Simply use the HPCC Driver to connect and access data just as you
would access any traditional database. The drivers is completely self-contained - no additional software
installation is required!
Access HPCC data through widely available tools. The
JDBC interface offers the greatest accessibility to HPCC data from Java based applications and developer technologies.
- Advanced wire-protocol SSL security for remote connectivity.
- Faster application deployment and configuration.
Connect To HPCC From BI, ETL, & Reporting Tools
JDBC is the most widely supported interface for connecting Java-based applications with data.
All kinds of BI, Reporting, ETL, Database, and Analytics tools offer the ability to read and
write data via JDBC connectivity.
The HPCC Driver wraps the complexity of accessing HPCC services in an easy-to-integrate,
pure Java JDBC Driver. Applications then access HPCC through the
HPCC Driver with simple Transact-SQL.
The CData JDBC Driver for HPCC hides the complexity of accessing data and provides additional powerful security features,
smart caching, batching, socket management, and more.
HPCC Application Integration
The HPCC Driver has the same JDBC architecture as the JDBC drivers for MySQL
and OLEDB, including Connection, Statement and ResultSet objects. Because of
this you can now access HPCC data in an easy, familiar way.
You can use the HPCC Driver through
popular IDEs (Eclipse, IntelliJ, NetBeans, etc.), in code through familiar classes, and in data controls available
through Swing, Eclipse SWT Widgets, etc.
Connection conn =
boolean ret = stat.execute("SELECT * FROM ECL Queries");
More Than Read-Only: Full Update/CRUD Support
HPCC Driver goes beyond read-only functionality to deliver full
support for Create, Read Update, and Delete operations (CRUD). Your end-users can interact
with the data presented by the HPCC Driver as easily as interacting with
a database table.
Connection conn =
String query = "UPDATE ECL Queries SET Where= ...";
PreparedStatement pstmt = conn.prepareStatement(query);

* Please visit our knowledge base to access how-to articles.
- Developer Friendly: Design-time support for all major Java IDEs, including Eclipse, IntelliJ, and NetBeans.
- JDBC Remoting: Our exclusive remoting feature allows hosting the JDBC connection on a server to enable connections from various clients on any platform (Java, .NET, C++, PHP, Python), using any standards-based technology (ODBC, JDBC, etc.). JDBC Remoting is enabled using the popular MySQL wire protocol server.
- Replication and Caching: Our replication and caching commands make it easy to copy data to local and cloud data stores such as Oracle, SQL Server, Google Cloud SQL, etc. The replication commands include many features that allow for intelligent incremental updates to cached data.
- String, Date, Numeric SQL Functions: The driver includes a library of over 50 functions that can manipulate column values into the desired result. Popular examples include Regex, JSON, and XML processing functions.
- Collaborative Query Processing: Our drivers enhance the data source's capabilities by additional client-side processing, when needed, to enable analytic summaries of data such as SUM, AVG, MAX, MIN, etc.
- Easily Customizable and Configurable: The data model exposed by our JDBC Drivers can easily be customized to add or remove tables/columns, change data types, etc. without requiring a new build. These customizations are supported at runtime using human-readable schema files that are easy to edit.
- Secure Connectivity: Includes standard Enterprise-class security features such as TLS/ SSL data encryption for all client-server communications.
MySQL/SQL Database entry points for HPCC ECL Queries Data
The CData JDBC drivers include powerful fully-integrated remoting capabilities
that makes HPCC ECL Queries data accessible from virtually anywhere. The drivers
include the optional ability to accept incoming SQL and MySQL client connections and service
standard database requests.
With the CData JDBC drivers, users can interact with HPCC ECL Queries data from any client
that supports SQL Server or MySQL: from web & mobile applications, to CRM and CMS systems, BI tools
like SQL Server Analysis Services, and even through popular management applications like MySQL Workbench.
Access HPCC ECL Queries data from virtually any application that can access external data.
Applications that can access SQL Server or MySQL data can now connect to HPCC ECL Queries with this driver.
Connect HPCC ECL Queries data with popular BI tools like SQL Server Analysis Services.
- Enable enterprise HPCC ECL Queries data integration through SQL Linked Server connectivity
Includes support for the MySQL and SQL (TDS) remote access protocols - industry standards for remote
- Offers advanced wire-protocol SSL security for remote connectivity
Connect to HPCC ECL Queries Data from Code
The HPCC Driver offers a standard SQL Server or MySQL interface to data,
with read/write (CRUD) support. This powerful remoting features makes it easy to connect your
applications with HPCC ECL Queries data regardless of your solution architecture.
Use one of the standard client libraries for accessing SQL/MySQL from
.NET, Java, PHP, Python, Ruby, Objective-C, etc. to start your integration with HPCC.
JDBC Driver Performance
With traditional approaches to remote access, performance bottlenecks can spell disaster
for applications. Regardless if an application is created for internal use, a commercial project, web, or mobile
application, slow performance can rapidly lead to project failure. Accessing data from any remote source has the potential
to create these problems. Common issues include:
- Network Connections - Slow network connections and latency issues are common in mobile applications.
- Service Delays - Delays due to service interruptions, resulting in server hardware or software updates.
- Large Data - Intentional or unintentional requests for large amounts of data.
- Disconnects - Complete loss of network connectivity.
The CData JDBC Driver for HPCC solves these issues by supporting powerful smart caching technology that can greatly
improve the performance and dramatically reduce application bottlenecks.
Smart caching is a configurable option that works by storing queried data into a local database. Enabling smart
caching creates a persistent local cache database that contains a replica of data retrieved from the remote source.
The cache database is small, lightweight, blazing-fast, and it can be shared by multiple
connections as persistent storage.
Caching with our JDBC Drivers is highly configurable, including options for:
Auto Cache - Maintain an automatic local cache of data on all requests. The provider will automatically
load data into the cache database each time you execute a SELECT query. Each row returned by the query will
be inserted or updated as necessary into the corresponding table in the cache database.
Explicit Cache - Cache only on demand. Developers decide exactly what data gets stored in the cache
and when it is updated. Explicit caching provides full control over the cache contents by using explicit
execution of CACHE statements.
- No Cache - All requests access only live data and no local cache file is created.
This powerful caching functionality increases application performance and allows applications to disconnect
and continue limited functioning without writing code for additional local storage and/or

Eclipse Integration - Data Explorer
As a JDBC Driver, HPCC JDBC Driver can be used to access and explore
HPCC data directly from the Data Source Explorers included in popular java IDEs.
It's easy. As a standard JDBC Driver, developers can connect the Data Source Explorer to HPCC JDBC Driver,
just like connecting to any standard database.
- Add a new Data Connection from the server explorer and select the HPCC Data Source
- Configure the basic connection properties to access your HPCC account data.
Explore real-time data! The HPCC JDBC Driver makes it easy to access live HPCC data directly from any modern Java IDE.
- After configuring the connection, explore the tables, views, and stored procedures provided by the HPCC JDBC Driver.
- These constructs return live HPCC data that developers can work with directly from within the IDE.
