0.4.0: Import local CSV File

This release adds support for importing local CSV files into an Exasol table. See the user guide for details.

The release also fixes the implementation of the driver.cancel() method. Before, it failed with error Cannot read properties of undefined (reading 'numResults'). Now the query correctly fails with the correct error message E-EDJS-25: SQL error: code: 'R0003', message: 'Client requested execution abort. ....

Compatibility

Starting with this release, we test the driver with Node.js LTS versions 22, 24 and 26. We no longer test with version 20 which is not maintained any longer.

Features

• #48: Added import from local CSV file

Bugfixes

• #62: Fixed cancelling query() and execute() calls

Minor logger update / CI tests update

Exasol Driver ts 0.3.1, released 2025-06-17

Code name: Minor logger update / CI tests update

Summary

• Reduced logger verbosity in trace mode to prevent potential leakage of sensitive information in trace statements.
• Improved error messages for certain connection issues.
• Updated CI tests to use Exasol Docker DB v8 with encryption enabled in Node.js context:
  • Browser-based CI tests use Exasol Docker DB v7.1.x without encryption.
  • Node-based CI tests use Exasol Docker DB v8.30.x with encryption.
• Currently, encryption testing is not possible with Exasol Docker DB v7.1.x due to incompatibilities with its SSL version.
• Enabling encryption in browser-based CI tests using Docker DB v8 will require a completely new approach. CI test infrastructure will need to be partially re-engineered to support this.
• Due to time constraints this will be implemented at a later date. A separate ticket has been created for this task.

Features

• #21: Add Exasol 8 to integration test
