Hi,
When I run sp_helpindex @objname='Testtable'
I got 10 indexes. 1 clustered and 9 non-clustered but when I see the node Indexes under that table, I can able to see only clustered index. I can't able to see the remaining index.
Why I can't able to see those indexes from SSMS?
We are using SQL 2008r2 standard eidition

Try doing a refresh? Maybe you have an old version of SSMS (just because you patch the server, doesn't patch your client software)?

You should be able to see database objects.

I am running from the local machine and we didn't upgrade the instance. Also I refreshed the db & Tables

But we restored the database from SQL 2005 to this instance (SQL 2008r2) but didn't change the compatibility to SQL 2008r2 because didn't test the application with new compatability. So just left the compatability to 90

Is that could effect the visibility of the indexes from SSMS?

Are they hypothetical indexes (from DTA)? Don't know if those show un with helpindex, but they won't in SSMS.

Try querying sys.indexes directly.

I am not sure those are created by DTA or some other tool but the description is

nonclustered, hypothetical located on PRIMARY

index name is IX_SQLdoctor_8_5_95f565ef22664301a95c1840be217031

See this article on Hypothetical indexes >> https://msdn.microsoft.com/en-us/library/ms190172(SQL.90).aspx

Use this query to list Hypothetical indexes:

SELECT *

FROM sys.indexes

WHERE is_hypothetical = 1

Those are hypothetical indexes. Is it better to keep or drop those hypothetical index?
