JSON data support for Azure SQL Data Warehouse is now in preview
Updated: June 26, 2019
Organizations are increasingly faced with dealing with multiple data sources and heterogeneous file formats, JSON being among the top ones, aside from CSV files. To speed up time to insight and minimize unnecessary data transformation processes, Azure SQL Data Warehouse now enables support for querying JSON data. This feature is now available in preview.
Business analysts can now use the familiar T-SQL language to query and manipulate documents that are formatted as JSON data. JSON functions, such as JSON_VALUE, JSON_QUERY, JSON_MODIFY, and OPENJSON are now supported in Azure SQL Data Warehouse. Azure SQL Data Warehouse can now effectively support both relational and non-relational data, including joins between the two, while enabling users to use their traditional BI tools, such as Power BI.
