Azure Functions can be invoked when a row in a SQL database is created, updated, or deleted through the Azure SQL trigger for Azure Functions, now available in public preview for C# functions. The Azure SQL trigger is compatible with Azure SQL Database, Azure SQL Managed Instance, and SQL Server.
Additionally, Azure SQL bindings for Azure Functions have expanded input and output binding support to Java, PowerShell, Python, JavaScript, and C# functions. 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 with an output binding.
To learn more about developing Azure Functions with the Azure SQL bindings and the Azure SQL trigger, visit the documentation. The library is open source and is available on GitHub and on NuGet.
