问题 By default if you connect to a remote SQL Server via an account that has access to say 1 of the 10 databases. You will still see in the Object Explorer all other databases, obviously due to permissions you cannot actually query them, but you can see their names. I have heard that there is a method that disable this behavior, but I've been unable to find the answer, does anyone know how to do this? To give an example I have a SQL Server called MyDbServer, it has 4 databases, MyDatabase

阅读更多关于 Django REST Framework: restrict data records access to the users created them

问题 I'm trying to figure out, what is the best way to manage model access permissions with Django. I have a table of items which belong to the users created them. All the items a managed via a RESTful API. When using this API I want to limit access to the items created by a given user. Do I have to create several tables or is it possible to achieve the same with just one table? If I have to use multiple tables, how do I correlate API requests with a particular table? 回答1: Ok, I found a way to do

Execute dynamic DDL in PL/SQL procedure through definer role permissions

阅读更多关于 Execute dynamic DDL in PL/SQL procedure through definer role permissions

问题 I want to perform some dynamic DDL in a procedure owned by an admin user. I'd like to execute this procedure with a technical operational user with definer rights (operational user doesn't have the create table role). The problem is the 'create table' permission is granted to the admin user through use of a role, which doesn't allow me to execute the DDL as it seems that roles don't count in named pl/sql blocks. create or replace PROCEDURE test_permissions AUTHID DEFINER AS v_query_string

CouchDB read/write restrictions on _users database

阅读更多关于 CouchDB read/write restrictions on _users database

I would like to restrict the user permissions so that a normal user is only able to read/write its own user document. I managed to set the write permissions such that a user can only edit their own document (via the validate_doc_update function in the design document). Now I only have to limit a user from viewing the user list or other user documents. If I set the database read permissions to the '_admin' role, then the user will not be able to view their own document, which it's not what I intend. Can this be done in a more general way? I.e. to set read permissions such that a user is able to

SQL Permissions to Add data and how to verify?

阅读更多关于 SQL Permissions to Add data and how to verify?

I'm looking for a good way to maintain permissions on who can add data to a database in a C# app and SQL Server 2005. I need to explain though to make this clear. So let's take an example of this: I have two users Bob and Jim , both have been added to the SQL permissions so they have write access to the database. Now all access is based on Domain User Accounts. All other users only have read access. Now I have a couple tables such as: Users UserPermissions Books BookPublishers So UserPermissions contains a list of Users and BookPublishers. So for example: Bob has permission to add books for MS
