How to Use a Microsoft Access Database to Update Presto Data in Real Time

Update Presto data by creating a linked table in Microsoft Access with the CData Presto ODBC Driver.

CData ODBC drivers connect your data to any database management tool that supports Open Database Connectivity (ODBC). This includes many of the most popular productivity tools, adding new capabilities for document sharing and collaboration. Using the CData ODBC driver for Presto, you can update live Presto data in Microsoft Access; for example, you can make updates that can be immediately seen by other users.

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 as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

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.

Create a Linked Table to Customer Data

Follow the steps below to create a linked table, which enables you to access live Customer data.

  1. On the External Data tab in Access, click ODBC Database. 👁 Use the Get External Data wizard to work with ODBC data sources in Access.
  2. Select the option to link to the data source. A linked table will enable you to read from and write data to the Customer table. 👁 Linked Tables enable you use the live connection to Presto that is provided by the driver.

  3. Select the CData Presto data source from the Machine Data Source tab.

    👁 DSNs listed in the Get External Data wizard.
  4. Select the Customer table. For more information on this table, see the "Data Model" chapter in the help documentation. 👁 Available tables. (Google is shown.)

  5. Double-click the linked table to make edits. The linked table will always have up-to-date data and any changes will be reflected back to the underlying table.

    👁 A linked table to the live data. (Google is shown.)

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.
