Today the ADBC Drivers Contributors released updated drivers for six database systems, available immediately via dbc. To update, just dbc install <driver> to get the latest version.

Updated Drivers

The newly released drivers, and some release highlights, are:

Google BigQuery driver version 1.11.2
Snowflake driver version 1.10.3
Trino driver version 0.3.1

  • Update transitive dependencies to pick up security updates. (This is the only change for the three drivers listed above. The drivers listed below also include dependency updates, in addition to other changes detailed separately.)

Microsoft SQL Server driver version 1.3.1

  • Test against SQL Server 2025.
  • Use NVARCHAR(MAX) for bulk ingest, not NTEXT (which is deprecated).
  • Fix a bug where reusing a statement to execute a query after a bulk ingest would give an empty result set.

MySQL driver version 0.3.1

  • Enable bulk ingest into a temporary table.
  • Fix a bug with bulk ingest and wide schemas.

Oracle Database driver version 0.5.1

This driver is available from Columnar’s private driver registry. See this blog post to learn more.

  • Support REAL and DOUBLE PRECISION types when the latest Instant Client is used.
  • Don’t use the DBA_PDBS view in GetObjects, which requires more permissions.

Amazon Redshift driver version 1.2.1

  • Optimize bulk ingest.
