Can SQL server cache a view result set

No, SQL Server never caches a view’s result set. A standard view is expanded into the calling query, and results are recomputed every time. Only execution plans and underlying data pages are cached. Indexed views are the only case where results are physically stored not cached.

In Microsoft SQL Server, a non-indexed view stores ONLY metadata (the SELECT definition) and it is expanded into the outer query with having no independent execution and also do not have persisted rows due to that nothing to cache as a result set.

Let’s see the demo

Non indexed view

Creating a table inserting few records and creating view

CREATE TABLE dbo.orderDemo (     OrderID INT IDENTITY PRIMARY KEY,     CustomerID INT NOT NULL,     Amount MONEY  NULL );  INSERT INTO dbo.orderDemo (CustomerID, Amount) VALUES (1, 100), (1, 200), (2, 300), (2, 400); create view vw_orderDemo as select orderId,CustomerID, Amount from dbo.orderDemo

See the data in view

When we are running the view internally it run as

select orderId,CustomerID, Amount from dbo.orderDemo

The view disappears during optimization.

SQL Server caches the compiled execution plan that applies to Ad-hoc queries and Stored procedures and Queries referencing views. Keep in mind Plan cache ≠ data cache.View result set is NOT cached because no persisted rows in view and No reuse of previously returned results. Each execution logically recomputes the result.

Indexed View does cache data because it is physically stored.

Creating an index view

CREATE VIEW dbo.orderSummary WITH SCHEMABINDING AS SELECT CustomerID, COUNT_BIG(*) AS TotalOrders FROM dbo.orderDemo GROUP BY CustomerID; GO  CREATE UNIQUE CLUSTERED INDEX IX_OrderSummary ON dbo.orderSummary(CustomerID);

See the data from this view.

Result is materialized on disk. Maintained synchronously on base table changes and acts like a real table + index. This is not caching this is storage.

Inserting view records.

INSERT INTO dbo.orderDemo (CustomerID, Amount) VALUES (3, 100), (3, 200), (3, 300), (4, 400);

Running the view.

So, result is not catch in the view. If it is cached then only, we can see the old result but we are getting the update result.

SQL Server never caches view results. What feels like caching is plan reuse, buffer-pool hits, or operator-level spooling. Indexed views store data  they don’t cache it. Anyone claiming otherwise is confusing execution mechanics with storage.
