Fresh out of the Arc90 Lab: SqlWatcher.
SqlWatcher lets you use your web browser to query a SQL Server 2005/2008 database. Big deal so far. But after returning your results to you, SqlWatcher watches the database and notifies you instantly when your query results change, re-running your query and appending the latest results to your web browser as needed. And it does it without polling or leaving connections open.
Is it magic? Only if you think Query Notifications, SqlDependency, and Service Broker are magic. But they can be hard to use. At least, before SqlWatcher.
It’s free and BSD. Please leave your feedback in the comments.
