You can use the sys.partition_schemes system catalog view to return a list of partition schemes in SQL Server.

Example

Here’s an example to demonstrate.

SELECT * FROM sys.partition_schemes;

Result:

+-----------------------+-----------------+--------+------------------+--------------+-------------+---------------+
| name                  | data_space_id   | type   | type_desc        | is_default   | is_system   | function_id   |
|-----------------------+-----------------+--------+------------------+--------------+-------------+---------------|
| MoviesPartitionScheme | 65606           | PS     | PARTITION_SCHEME | 0            | 0           | 65542         |
+-----------------------+-----------------+--------+------------------+--------------+-------------+---------------+

To save you from scrolling sideways, here it is again using vertical output:

name          | MoviesPartitionScheme
data_space_id | 65606
type          | PS
type_desc     | PARTITION_SCHEME
is_default    | 0
is_system     | 0
function_id   | 65542

In this case, I only have one partition scheme, and so that is listed.

This view actually inherits its first six columns from the sys.data_spaces view.

Find the Index

You can modify the query in order to provide more meaningful information.

Here’s an example where I join it with sys.indexes to return the relevant index, table, and schema.

SELECT 
    object_schema_name(i.object_id) AS [Schema],
    object_name(i.object_id) AS [Object],
    i.name AS [Index],
    s.name AS [Partition Scheme]
    FROM sys.indexes i
    INNER JOIN sys.partition_schemes s ON i.data_space_id = s.data_space_id;

Result:

+----------+----------+------------------------------+-----------------------+
| Schema   | Object   | Index                        | Partition Scheme      |
|----------+----------+------------------------------+-----------------------|
| dbo      | Movies   | PK__Movies__4BD2941AD44D2FCF | MoviesPartitionScheme |
+----------+----------+------------------------------+-----------------------+

Result using vertical output:

Schema           | dbo
Object           | Movies
Index            | PK__Movies__4BD2941AD44D2FCF
Partition Scheme | MoviesPartitionScheme

The sys.partition_schemes view requires membership in the public role.
