In this session, we will cover Data Virtualization for Azure SQL Database: with T-SQL we will query files in different format like CSV, Parquet, and Delta files in ADLS Gen2 or Blob Storage—no data movement or ETL required. We will configure database-scoped credentials, define external data sources and file formats, create external tables, and use OPENROWSET for on-the-fly queries. We will highlight real-world benefits: on-demand cold-data access, reduced storage costs, and built-in security with SAS tokens and Managed Identity.
