The SELECT permission was denied on the object 'Users', database 'XXX', schema 'dbo'

问题

I moved a database from SQL Server 2012 to Azure. I don't want to use the user master, so I created a user test. This is what I did for database XXX on Azure:

create user test from login test with default_schema=[dbo]
exec sp_addrolemember 'db_owner','test'

I checked, and the database objects I am interested in are all in the schema dbo. The table Users is in the schema dbo.

The connection string in my web project has test as the login. It produces the error message:

The SELECT permission was denied on the object 'Users', database 'XXX', schema 'dbo'

What does the error message mean and what can I do to let user test access the database XXX?

回答1:

I think the problem is with the user having deny privileges. This error comes when the user which you have created does not have the sufficient privileges to access your tables in the database. Do grant the privilege to the user in order to get what you want.

GRANT the user specific permissions such as SELECT, INSERT, UPDATE and DELETE on tables in that database.

回答2:

The syntax to grant select permission is:

USE YourDB;

GRANT SELECT ON dbo.functionName TO UserName;

回答3:

1. Open SQL Management Studio
2. Expand your database
3. Expand the "Security" Folder
4. Expand "Users"
5. Right click the user (the one that's trying to perform the query) and select Properties.
6. Select page Membership.

7. Make sure you uncheck

   db_denydatareader

   db_denydatawriter

This should go without saying, but only grant the permissions to what the user needs. An easy lazy fix is to check db_owner like I have, but this is not the best security practice.

This is how I was able to solve the problem when I faced it

1. Start SQL Management Studio.
2. Expand the Server Node (in the 'Object Explorer').
3. Expand the Databases Node and then expand the specific Database which you are trying to access using the specific user.
4. Expand the Users node under the Security node for the database.
5. Right click the specific user and click 'properties'. You will get a dialog box.
6. Make sure the user is a member of the db_owner group (please read the comments below before you use go this path) and other required changes using the view. (I used this for 2016. Not sure how the specific dialog look like in other version and hence not being specific)

回答5:

Grant permissions for that user is needed

回答6:

Check space of your database.this error comes when space increased compare to space given to database.

回答7:

Using SSMS, I made sure the user had connect permissions on both the database and ReportServer.

On the specific database being queried, under properties, I mapped their credentials and enabled datareader and public permissions. Also, as others have stated-I made sure there were no denyread/denywrite boxes selected.

I did not want to enable db ownership when for their reports since they only needed to have select permissions.

回答8:

I resolve my problem doing this. [IMPORTANT NOTE: It allows escalated (expanded) privileges to the particular account, possibly more than are needed for individual scenario].

1. Go to 'Object Explorer' of SQL Management Studio.
2. Expand Security, then Login.
3. Select the user you are working with, then right click and select Properties Windows.
4. In Select a Page, Go to Server Roles
5. Click on sysadmin and save.
