Question

Getting info on our table in Squirrel returns the index types as ints. I found Types of Indexes on Microsoft’s site, but it has no mapping to numeric values.

I’m on Linux so I can’t exactly pull up SQL Management Studio. Is there anywhere that actually maps the number values to Microsoft’s named types?

Sepcifically, I want to know what index type 1 and index type 3 are.

Answer 1

There are different mappings available.

The sp_indexes stored procedure returns the following index types:

0 = Statistics for a table 
1 = Clustered 
2 = Hashed 
3 = Other

On the other hand, the sys.indexes catalog view uses the following map:

0 = Heap
1 = Clustered
2 = Nonclustered
3 = XML
