How can we automate a process to insert the Purview link in Dedicated SQL pool Tables

You can’t really “insert the Purview link” into Dedicated SQL pool table metadata the way you would in SQL Server, because Dedicated SQL pool doesn’t support extended properties (so no sp_addextendedproperty approach).

What people do instead (automatable):

1. Create a mapping table in the SQL pool (e.g., schema/table/column -> Purview asset GUID + Purview URL). Populate it via a scheduled job (ADF/Synapse pipeline/Azure Function) that calls the Purview Data Map API to resolve assets and store the GUID/link.
2. For CSV exports, enrich during export: Join the data (or at least the export metadata) to your mapping table and add a column like purview_asset_guid or purview_link, or write a separate “sidecar” mapping file per export.
3. Best practice: store the stable identifier (Purview asset GUID) and generate the “clickable link” from a configurable URL template, since portal link formats can change.
