I have normalized tables in a database and to denormalize it, I created a view out of two tables. When I tried to create a clustered index on the view, it wouldn\'t let me,
Logically you are making two separate queries. 'A LEFT JOIN B' is just shorthand for '(A JOIN B) UNION A'
The first query is table A inner joined to table B. This gets an indexed view, since this is where all the heavy lifting is done.
The second query is just table A where any of the join columns are null. Make a view that produces the same output columns as the first query and pads them with nulls.
Just union the two results before returning them. No need for a workaround.
