Copy Activity Fails with "Incorrect syntax near 'INSERT BULK'" when using SQL Server Linked Service

Hi sshetty014 ,

Thank you for reaching out to Microsoft Community.

Although Fabric Warehouse supports the `BULK INSERT` T-SQL statement, using the SQL Server linked service against the Warehouse SQL analytics endpoint is not a fully supported sink pattern for Copy Activity bulk loading.

The SQL Server connector internally uses SQL server specific bulk insert operations (`INSERT BULK`) which are not fully compatible with the Fabric Warehouse endpoint, resulting in the syntax error.

For Fabric Warehouse destinations, the recommended approaches are:

* Use the native Fabric Warehouse connector in Copy Activity
* Use `COPY INTO` from OneLake/Lakehouse files
* Use Dataflow Gen2 or Notebook-based loading patterns

For dynamic multi destination pipelines, the recommended design is usually to branch logic based on sink type rather than reusing the SQL Server connector for Fabric Warehouse targets.

Thanks.
