If you do not use ROLE, then it works.

    What is the default role for the user tableau1? What is the vertica version?

    select * from users where user_name ilike 'tableau1';

    VMart=> select * from users where user_name ilike 'tableau1';

    could you please run alter user tableau1 default role dds_reader and see if it helps?

  • Did not help =(

    VMart=> alter user tableau1 default role dds_reader;
    ALTER USER
    VMart=> \c VMart tableau1
    Password:
    You are now connected to database "VMart" as user "tableau1".
    VMart=> select * from dds.test1;

    Try doing what Sruthi suggested except do it for user tableau3 (the owner of the view) instead: alter user tableau3 default role dds_reader;

    Then try to select from the view as one of the other users by first setting the role dds_reader or also making it their default role.

  • alter user tableau3 default role dds_reader;
    

    That's how it worked. Thanks

    Can I somehow activate the available roles in the default role for all users?

    Something like:

    ALTER DATABASE VMart SET PARAMETER EnableAllRolesOnLogin=1;
    
  • DaveTDaveT Employee

    That will remove the requirement to issue SET ROLE. But it doesn't appear that will allow the view access to work. It appears that the specific role enablement is checked to ensure that the view owner has SELECT WITH GRANT OPTION on the base table.

  • SruthiASruthiA Employee

    As Dave mentioned EnableAllRolesOnLogin parameter will not help. One thing you can do is making all roles as default roles to the user once they are granted.

    dbadmin=> create user user1;
    CREATE USER
    dbadmin=> create role test1;
    CREATE ROLE
    dbadmin=> grant test1 to user1;
    GRANT ROLE

    select set_config_parameter('EnableAllRolesOnLogin',1);
    -[ RECORD 1 ]--------+---------------------------
    set_config_parameter | Parameter set successfully

    dbadmin=> SELECT user_name, default_roles, all_roles FROM users WHERE user_name = 'user1';
    user_name | default_roles | all_roles
    -----------+---------------+-----------
    user1 | | test1
    (1 row)

    dbadmin=>

    dbadmin=> ALTER USER user1 DEFAULT ROLE ALL;
    ALTER USER

    dbadmin=> SELECT user_name, default_roles, all_roles FROM users WHERE user_name = 'user1';
    user_name | default_roles | all_roles
    -----------+---------------+-----------
    user1 | test1 | test1
    (1 row)

    dbadmin=>

  • Thank you SruthiA.
    I will use - DEFAULT ROLE ALL
