Displaying Information About Indexes

To see the indexes that exist on a table, use the sp_helpindex system procedure. A maximum of eight indexes will be displayed. The sysindexes system table contains information about all indexes.

Here's a sample report about the authors table:

sp_helpindex authors
index_name
index_description
index_keys
-------------
-------------------------------
-----------------
UPKCL_auidind
clustered, unique, primary key 
located on default
au_id
aunmind
nonclustered located on default
au_lname, 
au_fname

(1 row(s) affected)

When used with the table name, the sp_help system procedure also reports indexes on a specific table.
