Examples

A. Use CURRENT_USER to return the current username

This example declares a variable as char, assigns the current value of CURRENT_USER to it, and then returns the variable with a text description.

SELECT 'The current user is: '+ convert(char(30), CURRENT_USER)

Here is the result set:

--------------------------------------------------- 
The current user is: dbo                            

(1 row(s) affected)

B. Use CURRENT_USER as a DEFAULT constraint

This example creates a table that uses CURRENT_USER as a DEFAULT constraint for the order_person column on a sales row.

USE pubs
IF EXISTS (SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES
      WHERE TABLE_NAME = 'orders2')
   DROP TABLE orders2
GO
SET NOCOUNT ON
CREATE TABLE orders2
(
 order_id int IDENTITY(1000, 1) NOT NULL,
 cust_id  int NOT NULL,
 order_date datetime NOT NULL DEFAULT GETDATE(),
 order_amt money NOT NULL,
 order_person char(30) NOT NULL DEFAULT CURRENT_USER
)
GO
INSERT orders2 (cust_id, order_amt)
VALUES (5105, 577.95)
GO
SET NOCOUNT OFF

This query selects all information from the orders2 table.

SELECT * 
FROM orders2

Here is the result set:

order_id    cust_id     order_date             order_amt    order_person                   
----------- ----------- ------------------- ------------- -------------- 
1000        5105        Mar 4 1998 10:13AM      577.95           dbo                            

(1 row(s) affected)
