This question already discusses about how can you be notified about SQL changes using SqlDependency class. However, it is not just unicorns and rainbows, so you should also read these resource before pursuing this path:

1) Consider polling - check this question

2) Read the limitations - check here to see that there are lots of limitations

3) Caching using SqlCacheDependency , if you are using ASP.NET
