Public preview: Azure SQL bindings for Azure Functions

Azure Functions can now interact with SQL databases through input and output bindings for Azure SQL. The library to enable this functionality is in public preview and is available from [NuGet](https://www.nuget.org/packages/Microsoft.Azure.WebJobs.Extensions.Sql) as Microsoft.Azure.WebJobs.Extensions.Sql. With Azure SQL bindings, data can be input from a database to the function with an input binding and data can be output from the function to the database. Configuring these bindings is accomplished with a small number of parameters, including specification of the database query or table and the connection string. To learn more about developing Azure Functions with the Azure SQL bindings for Azure Functions, visit the [documentation](https://docs.microsoft.com/azure/azure-functions/functions-bindings-azure-sql). The library is open source and is available on [GitHub](https://github.com/Azure/azure-functions-sql-extension). * Azure functions * Azure SQL * SDK and Tools * Open Source * [ Azure SQL](https://azure.microsoft.com/en-gb/products/azure-sql/) * [ Azure functions](https://azure.microsoft.com/en-gb/products/functions/)
