⟩ How To View Existing Indexes on an Given Table using sys.indexes?
Another way to view existing indexes defined for a given table is to use the system view called "sys.indexes". The tutorial exercise shows you how many indexes were defined from the previous tutorial on table "ggl_links":
USE GlobalGuideLineDatabase;
GO
SELECT * FROM sys.indexes WHERE object_id = (
SELECT object_id FROM sys.tables WHERE name = 'ggl_links'
);
GO
object_id name index_id type_desc is_unique--------- ------------- -------- ---------- ---------
421576540 NULL 0 HEAP 0
421576540 ggl_links_id 2 NONCLUSTERED 0
421576540 ggl_links_url 3 NONCLUSTERED 0
The extra line in the query result is not a real index at this moment. It will be explained in another tutorial.
