DB role unable to delete-The database principal owns a schema in the database, and cannot be dropped.


  • I created a role . Initially when I created schema assigned as dbo. now I change back to  role1 as image. But I am unable to drop the role.

    I run following commands


    AUTHORIZATIONONROLE::[role1] TO[role1];

    Still getting following error

    Drop failed for DatabaseRole 'role1'.  (Microsoft.SqlServer.Smo)

    The database principal owns a schema in the database, and cannot be dropped.

    Any one can help me on . Great Thanks

  • Hi ashwan,

    That means, you are trying to drop a user owning a schema. In order to drop the user, you have to find the schema that’s assigned and then transfer the ownership to another user/role or to drop it.

    You can find out which schema is owned by this user with the query below:

    SELECT name FROM  sys.schemas WHERE principal_id = USER_ID('myUser')

    Then refer to Uri Dimant's script to drop the role.
