How can I provide an Index Hint to a MS-SQL Server Indexed View? -
i have indexed view fooview
.
i've created following indexes against it:
create unique clustered index ix_foo1 on [fooview](someid, anotherid)
create nonclustered index ix_foo2 on [fooview](someid)
is possible use hint against ix_foo2
? keeps using ix_foo1
when use with (noexpand)
hint.
yes straightforward
create table dbo.footable ( someid int, anotherid int, filler char(8000) ); go create view dbo.fooview schemabinding select someid, anotherid, filler dbo.footable go create unique clustered index ix_foo1 on dbo.fooview(someid, anotherid) create nonclustered index ix_foo2 on dbo.fooview(someid) go select someid dbo.fooview (noexpand) --no hint non clustered index chosen automatically select * dbo.fooview (noexpand) --no hint clustered index chosen automatically select * dbo.fooview (noexpand, index = ix_foo2) --with hint nonclustered index forced
execution plans
(note forcing index hint led more expensive plan leaving choice optimiser though)
