@Liam Metzger Thank you for reaching out to Microsoft Q&A. Based on your statement, you want to update or delete table entities in HttpTrigger Azure function (Java).
Unfortunately, output binding only supports creating new entities in a table and you would need to use Azure SDK directly (refer Azure Tables output bindings for Azure Functions).
Here are some sample code snippets for Update an entity and Delete an entity which use Azure Tables client library for Java. This would help you in writing custom code in your HttpTrigger Functions. I hope this answers your question and feel free to reach if you face any issues or have any questions. I would be happy to assist you.
If you have any feedback or suggestion to our product team, feel free to post it in Azure Functions so that others can also upvote it too.
Please 'Accept as answer' and ‘Upvote’ if it helped so that it can help others in the community.
