Any help would be appreciated
@GrantSmith is correct that you can't use Workbench for that purpose. There is a MS SQL Writeback Connector, though. Here's the KB Article:
Here's a screenshot of the connector if you go through Data Center and Connectors and search for writeback. In the search results, it does have a beta tag on it.
You can't use workbench to write back to MS SQL. It's only to pull data from the defined sources. There doesn't appear to be a writeback tile to use for MS SQL either but only Postgres, Maria and MySQL databases.
Interesting as there isn't a Microsoft SQL Writeback Connector listed in the Data Connectors in my instance. I'll have to dig into why and if it's still supported. Thanks for the KB article.
@GrantSmith Try to contact your DOMO CSM to enable it.
