SQL-Server Performance: What is faster, a stored procedure or a view?

Unfortunately, they're not the same type of beast.

A stored procedure is a set of T-SQL statements, and CAN return data. It can perform all kinds of logic, and doesn't necessarily return data in a resultset.

A view is a representation of data. It's mostly used as an abstraction of one or more tables with underlying joins. It's always a resultset of zero, one or many rows.

I suspect your question is more along the lines of:

Which is faster: SELECTing from a view, or the equivalent SELECT statement in a stored procedure, given the same base tables performing the joins with the same where clauses?
