Does anyone know of a good script to get all the non-clustered indexes for SQL Server 2005?
For all nonclustered indexes in a particular database:
select object_name(object_id) as tablename, *
from sys.indexes where type_desc = 'NONCLUSTERED'
This will return system and non-system tables. Alternatively:
select t.name as tablename, i.*
from sys.indexes i, sys.tables t
where i.object_id = t.object_id
and i.type_desc = 'NONCLUSTERED'
for only user-land nonclustered indexes.
You can get all indices for a table using
exec sp_helpindex 'tablename'
You can insert this into a table, and delete all rows where the INDEX_DESCRIPTION starts with 'CLUSTERED'
Here is a script for all indices in a database
declare @EmptyString varchar(1)
select @EmptyString = ''

select @IgnoreDuplicateKeys = name from master.dbo.spt_values
where type = 'I' and number = 1 --ignore duplicate keys
select @Unique = name from master.dbo.spt_values
where type = 'I' and number = 2 --unique
