Use the CData ODBC Driver to connect to Presto data in DBeaver.

NOTE: The Legacy ODBC driver was removed in DBeaver Community Edition 23.1. As an alternative, you can use a CData JDBC Driver (learn how here: How to Connect DBeaver to Presto via JDBC). If you need to use ODBC Drivers, refer to the DBeaver Documentation.


The CData ODBC Driver for Presto enables access to live data from Presto under the ODBC standard, allowing you work with Presto data in a wide variety of BI, reporting, and ETL tools and directly, using familiar SQL queries. This article shows how to manage Presto data with visual tools in DBeaver like the query browser.

The CData ODBC drivers offer unmatched performance for interacting with live Presto data in DBeaver due to optimized data processing built into the driver. When you issue complex SQL queries from DBeaver to Presto, the driver pushes supported SQL operations, like filters and aggregations, directly to Presto and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side. With built-in dynamic metadata querying, you can manage and analyze Presto data.

About Presto Data Integration

Accessing and integrating live data from Trino and Presto SQL engines has never been easier with CData. Customers rely on CData connectivity to:

  • Access data from Trino v345 and above (formerly PrestoSQL) and Presto v0.242 and above (formerly PrestoDB)
  • Read and write access all of the data underlying your Trino or Presto instances
  • Optimized query generation for maximum throughput.

Presto and Trino allow users to access a variety of underlying data sources through a single endpoint. When paired with CData connectivity, users get pure, SQL-92 access to their instances, allowing them to integrate business data with a data warehouse or easily access live data directly from their preferred tools, like Power BI and Tableau.

In many cases, CData's live connectivity surpasses the native import functionality available in tools. One customer was unable to effectively use Power BI due to the size of the datasets needed for reporting. When the company implemented the CData Power BI Connector for Presto they were able to generate reports in real-time using the DirectQuery connection mode.


Getting Started


Connect to Presto

If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can configure the DSN using the Microsoft ODBC Data Source Administrator. This is also the last step of the driver installation. See the "Getting Started" chapter in the Help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.

Set the Server and Port connection properties to connect, in addition to any authentication properties that may be required.

To enable TLS/SSL, set UseSSL to true.

Authenticating with LDAP

In order to authenticate with LDAP, set the following connection properties:

  • AuthScheme: Set this to LDAP.
  • User: The username being authenticated with in LDAP.
  • Password: The password associated with the User you are authenticating against LDAP with.

Authenticating with Kerberos

In order to authenticate with KERBEROS, set the following connection properties:

  • AuthScheme: Set this to KERBEROS.
  • KerberosKDC: The Kerberos Key Distribution Center (KDC) service used to authenticate the user.
  • KerberosRealm: The Kerberos Realm used to authenticate the user with.
  • KerberosSPN: The Service Principal Name for the Kerberos Domain Controller.
  • KerberosKeytabFile: The Keytab file containing your pairs of Kerberos principals and encrypted keys.
  • User: The user who is authenticating to Kerberos.
  • Password: The password used to authenticate to Kerberos.

Finally, set the "Map To WVarchar connection property to False in the DSN Configuration window for the driver. This configuration will allow string types to be mapped to SQL_VARCHAR and prevent SQL_WVARCHAR types from being displayed as NULL.

Connecting to the Presto ODBC Data Source in DBeaver

  1. Open the DBeaver application and in the Database menu, select the New Database Connection option. 👁 Creating a new Database Connection
  2. In the 'Connect to a database' window, select ODBC and click Next. 👁 Creating a new Database Connection
  3. In the Database/Schema field, enter the DSN name (CData Presto Source by default). It will be automatically added to the JDBC URL as well.
  4. Click the Test Connection button. You should receive a 'Connected' message after DBeaver has detected the DSN, along with details about the driver if the connection is successful. 👁 Successfully tested connection

Query Presto Data

You can now query information from the tables exposed by the data source connection. You can expand the database structure in order to view all the tables. You can retrieve the table's data by right-clicking on a table name and selecting View data. The data will then be available in the Data tab.

Presto ODBC Driver

The Presto ODBC Driver is a powerful tool that allows you to connect with live data from Presto, directly from any applications that support ODBC connectivity.

Access Presto data like you would a database - read, write, and update Presto Tables, etc. through a standard ODBC Driver interface.
