Question of the Day

Who am I?

If I want to track which login called a stored procedure and use the value in an audit, what function can I use to replace the xxx below?

create procedure AddNewCustomer
  @customername varchar(200)
AS
BEGIN
    DECLARE @added VARCHAR(100)
    SELECT @added = xxx

    IF @customername IS NOT NULL
      INSERT dbo.Customer
      (
          CustomerName,
          AddedBy 
      )
      VALUES
      (@customername, @added)
END
