Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Analytics Platform System (PDW) SQL analytics endpoint in Microsoft Fabric Warehouse in Microsoft Fabric

Returns one row for each member of each database role. Database users, application roles, and other database roles can be members of a database role. To add members to a role, use the ALTER ROLE statement with the ADD MEMBER option. Join with sys.database_principals to return the names of the principal_id values.

Column name Data type Description
role_principal_id int Database principal ID of the role.
member_principal_id int Database principal ID of the member.


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 was granted some permission. For more information, see Metadata Visibility Configuration.


The following query returns the members of the database roles.

SELECT AS DatabaseRoleName,   
   isnull (, '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  
WHERE DP1.type = 'R'
