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, as the view was created with a left outer join. I used a left join because I want the null values to show up in the resulting view, much like how it was suggested in this earlier post.
Question on join where one column one side is null
The table structure and relationship is very much similar to what was described in the above link.
I seemed to hit a wall here as I couldn't convert my left join into an inner join, as that would exclude all records with null values on any of the joined columns. My questions are:
There is a "workaround" here that involves check for
NULL in the join and having a
NULL representation value in the table
INSERT INTO Father (Father_id, Father_name) values(-255,'No father')
JOIN [dbo].[son] s on isnull(s.father_id, -255) = f.father_id
