Just note that External tables are still in public preview.Let us first see what is Synapse SQL pool and how can be used from Azure SQL. External tables with type RDBMS can be used in any Azure SQL flavor. In this article, I will explain how to leverage a serverless Synapse SQL pool as a bridge between Azure SQL and Azure Data Lake storage.This article applies both on Azure SQL database and Azure SQL managed instance. Click Break Link.You might also leverage an interesting alternative – serverless SQL pools in the Azure Synapse Analytics. Note: To remove multiple links, hold down , and then click each link.
In the previous article, I have explained how to leverage linked servers to run 4-part-name queries over Azure storage, but this technique is applicable only in Azure SQL Managed Instance and SQL Server,In this article, I will show you how to connect any Azure SQL database (single database or managed instance database) to Synapse SQL endpoint using the external tables that are available in Azure SQL. A variety of applications that cannot directly access the files on storage can query these tables.You can leverage Synapse SQL compute in Azure SQL by creating proxy external tables on top of remote Synapse SQL external tables. This way, your applications or databases are interacting with “tables” in so called Logical Data Warehouse, but actually they read the underlying Azure Data Lake storage files.Serverless Synapse SQL pool exposes underlying CSV, PARQUET, and JSON files as external tables. You can access the Azure Data Lake files using the T-SQL language that you are using in Azure SQL.The T-SQL/TDS API that serverless Synapse SQL pools expose is a connector that links any application that can send T-SQL queries with the Azure storage. ![]() Now you can connect your Azure SQL service with external tables in Synapse SQL.The activities in the following sections should be done in Azure SQL.

Then create a credential with Synapse SQL user name and password that you can use to access the serverless Synapse SQL pool. You can use the following script: CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'put some strong password here' CREATE DATABASE SCOPED CREDENTIAL SynapseSqlCredentialCREATE EXTERNAL DATA SOURCE SynapseSqlDataSourceLOCATION = '-ondemand.sql.azuresynapse.net',You need to create a master key if it doesn’t exist. Ralink wireless utility for macQuery Azure storage filesWhen you prepare your proxy table, you can simply query your remote external table and the underlying Azure storage files from any tool connected to your Azure SQL database:Azure SQL will use this external table to access the matching table in the serverless SQL pool and read the content of the Azure Data Lake files. This external should also match the schema of a remote table or view. In addition, it needs to reference the data source that holds connection info to the remote Synapse SQL pool. ![]() You can learn more about the rich query capabilities of Synapse that you can leverage in your Azure SQL databases on the Synapse documentation site.
