SQL Server Management Studio allows you to view effective permissions on an object, but it’s limited in a few important respects. To work around some of those limitations, I’ve built a stored procedure to display all the defined and effective permissions across an entire SQL Server database.

The SQL Server security model, part 2: securables
Continuing on last week’s post on security principals, this week’s installment in the series on SQL Server security takes a look at securables.
The SQL Server security model, part 1: principals
There are a number of layers in the SQL Server security model, giving you a nearly infinite number of ways to set up access control on your server and databases. Security is a huge topic, and there are literally entire books on it, so this series of articles is designed to give you just a quick overview of the SQL Server security model to get you started.
In this first installment, I’ll go through the different types of security principals that are available, as well as how they connect to each other.
Directed acyclic graphs vs parent-child hierarchies
We’ve recently looked at ways to work with parent-child hierarchies, particularly in reporting scenarios. Regular parent-child hierarchies are great when working with dimensions that are ragged, but they have a critical limitation – any given node in the tree can only have a single parent node. A great solution to this problem is a DAG – directed acyclic graph.
