Querying Private Blob Storage Containers with Azure Synapse Analytics

Dennes Torres looks at some private information:

The queries from the previous article were made against the public container in the blob storage. However, if the container is private, you will need to authenticate with the container. In this article, you’ll learn how to query private blob storage with SQL.

NOTE: Be sure that the Azure Synapse Workspace and the storage account with the sample files are set up before following along with this article. You will also need to replace your storage account URL each time that a storage account URL is used in the article.

There are three possible authentication methods, and these methods may have some variation according to the type of storage account and the access configuration. I will not dig into details about storage here and leave that for a future article.

Read on for the three authorization methods and a lot of detail on using SAS tokens (the preferred method) to access this data.
