Isolate the views tied to a target table in SQL Server with this query:

-- Replace 'YourTable' with your actual table name; Aliens won't do it for you
SELECT v.name AS ViewName
FROM sys.views v
JOIN sys.sql_expression_dependencies sed ON v.object_id = sed.referencing_id
WHERE sed.referenced_entity_name = 'YourTableName';

Replace 'YourTableName' with the actual table name. What you receive is a list of direct dependent views for a specific table; served hot and plain like buttered toast.

Understanding the importance

Peeking into the dependencies in your database is like trail tracking in the forest; it protects you from unforeseen cliffs or bear encounters (i.e. breaking your application). Knowing the views that rely on a particular table enables you to foresee the consequences of schema adjustments — making sure your hike isn't disrupted.

Beware of false positives. INFORMATION_SCHEMA.VIEW_DEFINITION might lead you down a rabbit hole with partial matches — a regular Lewis Carroll experience. More reliable are OBJECT_DEFINITION function and sys.sql_expression_dependencies. They give you the exact matches, like a GPS in the dependency jungle.

Most critical is reflecting any alterations in a base table in all contingent views. It's the key to maintaining the constellation of integrity and consistency in your database universe. For a database administrator, performing regular maintenance checks using queries like the above is like a Jedi Knight practicing lightsaber drills.

Alternatives and additional tools

Leveraging system views

Filtering queries on sys.objects by type 'V' for views or INFORMATION_SCHEMA.VIEW_TABLE_USAGE opens up another door to spot views linked to a specific table. It’s like using night vision goggles to navigate a pitch-black room.

Visualing object relationships

Visual tools like ApexSQL Search or Red-Gate's SQL Search are the Iron Man suits of SQL Server. They not only reveal the references to a table, but also visualize the relationships between database objects.

Unraveling complex dependencies

sys.sql_expression_dependencies view can reveal convoluted references like a detective unveiling the criminal in a room full of suspects. It’s a Sherlock Holmes' magnifying glass for a bewildering web of dependencies.

Advanced dependency exploration

In your labyrinth of complex dependencies, some simple breadcrumbs (basic SQL queries) might not lead you to all secrets. For those phantom-like encrypted or system objects, the View Dependencies feature in ApexSQL Search becomes your Harry Potter's invisible cloak.

Handling dynamic SQL

Where dynamic SQL is present within views, finding dependencies can be like finding Waldo on steroids. Due to the mutable nature of dynamic SQL, standard dependency views might miss some. Here, you might require additional methods to identify these elusive dependencies.

Dealing with large databases

When you have a large database, it's like being a zookeeper in Jurassic Park. Ensuring optimum performance while keeping all dependencies in check is essential. Think of it as sorting out Velociraptors from the gentle Brachiosaurus in your SQL Jurassic world.
