|Column name||Data type||Description|
|role_principal_id||int||Database Principal ID of the role.|

Any user can view their own role membership. To view other role memberships requires membership in the db_securityadmin fixed database role or VIEW DEFINITION on the database.
The visibility of the metadata in catalog views is limited to securables that a user either owns or on which the user has been granted some permission. For more information, see Metadata Visibility Configuration.
The following query returns the members of the database roles.
SELECT DP1.name AS DatabaseRoleName, isnull (DP2.name, 'No members') AS DatabaseUserName FROM sys.database_role_members AS DRM RIGHT OUTER JOIN sys.database_principals AS DP1 ON DRM.role_principal_id = DP1.principal_id LEFT OUTER JOIN sys.database_principals AS DP2 ON DRM.member_principal_id = DP2.principal_id ORDER BY DP1.name;
