How can you grant access to a user for all databases on a SQL Server instance?
Which setting trumps the others? How do I undo security? In other words, if SQL Server sees no applicable permissions for a user, the user has no access.
If you're familiar with Windows file or share permissions, it works the same way. However, before we demonstrate that, let's do some setup of a test role and a test user in a test database I've created aptly called TestDB: Re-use this query to see the permissions after each change: After issuing the revoke command, re-run the test harness queries above against that table and you'll see that the user cannot query the table any longer.
It removes a permission at the level specified to the security principal user or role specified. That's why we say it undoes a permission. DENY trumps all other access. Try just applying this permission, re-checking the permission, and then testing the user's access to both Test.
If you're not familiar with schemas and how they affect permissions, see this tip on nested permissions due to securables. Sometimes, if you look for an explicit permissions against a table or stored procedure, you won't see it. If this is the case, then the permission is on a securable that contains the object.
That's what we're doing here. And I'm only applying it to the Test. Now re-run the test harness queries.
You'll see the access is denied. However, you can still query Test. There isn't a DENY applied against it.To prevent the users from accessing SQL Server, you segment the network, so they cannot access SQL Server from their desktops and laptops.
It is not a bad idea to combine this with application roles and grant no permissions to the users.
You can use SQL Server tools or Transact SQL statements to manage user database privileges. Privileges on datasets should be granted or revoked by the dataset owner using the Privileges dialog box or Change Privileges geoprocessing tool in ArcGIS for Desktop.

We'll use standard SQL Server access control mechanisms to control read and write access to the table: All users of the database should be members of the db_datareader role to gain read access to the BlogPosts table (or you could GRANT them SELECT permission on the BlogPosts table).
To use remote data access (RDA), you must grant access to the Microsoft SQL Server database based on how Microsoft Internet Information Services (IIS) and SQL Server Authentication are configured. This step can be completed by implementing RDA programmatically. I want a SQL Server login that can READ, WRITE and View definition on all databases.
After doing: USE master; GRANT VIEW ANY Definition TO [a]; It looks like I have to GRANT CONNECT and read/write to each and every single database.
