Question

I use С# Express with Entity Framework. And not very good in SQL Server scripting.

So, I have this table

CREATE TABLE DataTable
(
  Id                INT              NOT NULL  ,
  Value             VARCHAR(20)          NULL  ,
  Author            ???????????      NOT NULL  ,
  CreateTime        DATETIME         NOT NULL  ,  
  CONSTRAINT PK_DataTable PRIMARY KEY CLUSTERED (num ASC) 
  ON [PRIMARY] 
)

Tell me please, how to write current Server user as author of data commit to my table.
Users enter through a local network in SQL Serve authorization mode.
It should be pretty transparently for c# programmer, and it should be handle on server side.

This would be a great place for a trigger. Database triggers are often used for logging operations such as the one you’re describing. In the trigger simply include the current user in your insert data.

There is a complete sample here.
