I have a view (actually, it's a table valued function, but the observed behavior is the same in both) that inner joins and left outer joins several other tables. When I query this view with a where clause similar to

SELECT *
FROM [v_MyView]
WHERE [Name] like '%Doe, John%'

... the query is very slow, but if I do the following...

SELECT *
FROM [v_MyView]
WHERE [ID] in 
(
    SELECT [ID]
    FROM [v_MyView]
    WHERE [Name] like '%Doe, John%'
)

it is MUCH faster. The first query is taking at least 2 minutes to return, if not longer where the second query will return in less than 5 seconds.

Any suggestions on how I can improve this? If I run the whole command as one SQL statement (without the use of a view) it is very fast as well. I believe this result is because of how a view should behave as a table in that if a view has OUTER JOINS, GROUP BYS or TOP ##, if the where clause was interpreted prior to vs after the execution of the view, the results could differ. My question is why wouldn't SQL optimize my first query to something as efficient as my second query?
