Does clustered index on foreign key column increase join performance vs non-clustered ?
- by alpav
In many places it's recommended that clustered indexes are better utilized when used to select range of rows using BETWEEN statement. When I select joining by foreign key field in such a way that this clustered index is used, I guess, that clusterization should help too because range of rows is being selected even though they all have same clustered key value and BETWEEN is not used.
Considering that I care only about that one select with join and nothing else, am I wrong with my guess ?
