ODBC Driver Version 2.1.1

Release Date: 14th November 2019

Qubole has released a new version of ODBC driver for Linux, Mac, and Windows. Qubole supports two variants of its ODBC drivers:

  • Series 2.1.x (starting with version 2.1.1) is based on top of AWS SDK and hence it has inherent support for accessing AWS S3 buckets that require signature version V4.
  • Series 2.2.x is based on older (1.X.X) releases and does not support accessing AWS S3 buckets that require signature version V4.

Unless stated otherwise, features are generally available, available as self-service and enabled by default. For more information, see Launch Stage and Availability of Features.

List of Changes


  • ODBC-315: Earlier, Qubole ODBC driver was using two API calls (Command API followed by Results API to fetch results location) when USE_S3 (on Linux/Mac) or UseS3 (on Windows) was enabled. Now, this enhancement replaces that with a single API call. This helps in reducing the overall command latency.
  • ODBC-343: Qubole has added an optimization to reduce the number of calls to Qubole APIs. Specifically, Qubole ODBC drivers do not make a call to get credentials on every connect call if those credentials have already been obtained during a previous connect call. This enhancement helps reduce the overall latency due to additional Qubole API calls.

Bug Fixes

  • ODBC-244: This fixes the issue with current_date, current_time, and current_timestamp keywords in Qubole ODBC driver.

  • ODBC-322: This fixes the data loss issue encountered in releases 2.0.0 and 2.1.0 (faced when NULL (0x00) characters were present in the Results data).

  • ODBC-323: This fixes the issue in ODBC Driver 2.0 and 2.1 due to which malformed metadata queries were created for columns having spaces and special characters.

  • ODBC-331: Starting this version, ODBC driver for Linux only creates system-level DSNs during its installation. For details on steps to create user-level DSNs, see Creating a User-level DSN.

  • ODBC-341: It is a fix for the issue with Linux ODBC installer wherein it was overwriting /etc/qubole.odbc.ini if it was missing ODBC Data Sources stanza. With this fix, if /etc/qubole.odbc.ini that already exists, was missing the ODBC Data Sources stanza, the installer now adds this stanza and adds Qubole DSN.

    In addition, this fix:

    • Resolves the issue wherein while uninstalling the driver, systems with unixODBC received the following insignificant error: cannot remove '/etc/profile.d/qds-odbc.sh': No such file or directory.
    • Removes the ODBCInstLib key in /etc/qubole.odbc.ini on Linux.
