Oracle to Azure Synapse query

edited Feb 16, 2026 11:45PM in Gateways, Oracle Lite, Oracle DB Mob. Server, TimesTen (MOSC) 3 commentsAnswered

We currently execute select queries from an Oracle 19c db using a HS link to a view on a local SQL Server. The SQL Server view in turn queries an Azure Synapse object via a linked server, but this query chain hangs intermittently.

I would like to query the Azure Synapse object directly from the Oracle db instead. I've tried configuring heterogeneous services to Azure Synapse. It connects okay but is failing with the below error. I'm using the latest Microsoft latest libmsodbcsql driver (18.6) on Linux (where the Oracle db is located).

Has anyone managed to find an HS or odbc.ini setting to get around this error?
