Issues Determining an Individual SQL Server User's Permissions

Recently I was supporting a third party application. It queries to determine what tables it has permissions to before it proceeds with the rest of its functionality. We had implemented permissions based on the best practice of creating roles, assigning the permissions to the roles, and then making the users members of the roles. The application was querying INFORMATION_SCHEMA.TABLE_PRIVILEGES and of course didn't find any permissions directly against the user in question. We ended up granting explicit permissions to the user so the application would work, but I'm more interested in the general case. How can I determine permissions for an individual user?

Data Generator Source Adapter

This component needs little explanation. It generates random integer (DT_I4) and string (DT_WSTR) data and places them in the pipeline. You specify how many columns of each you would like and for any string columns you pass a fixed length value. You then need to specify how many rows in total you require to be generated. This component is used by us to do testing of the pipeline and components downstream.

Question of the Day

Adding and Dropping Columns I

I have this table in my SQL Server 2022 database: 

CREATE TABLE [dbo].[CityList]
(
[CityNameID] [int] NOT NULL IDENTITY(1, 1),
[CityName] [varchar] (30) COLLATE SQL_Latin1_General_CP1_CI_AS NULL
) ON [PRIMARY]
GO
I decide to add two new columns for the StateProvince and Country. What code should I use?
