HOST_NAME ()  

nvarchar(128)

When the parameter to a system function is optional, the current database, host computer, server user, or database user is assumed. Built-in functions must always be followed by parentheses.

System functions can be used in the select list, in the WHERE clause, and anywhere an expression is allowed.

The client application provides the workstation name and can provide inaccurate data. Do not rely upon HOST_NAME as a security feature.

The following example creates a table that uses HOST_NAME() in a DEFAULT definition to record the workstation name of computers that insert rows into a table recording orders.

CREATE TABLE Orders  
   (OrderID     int        PRIMARY KEY,  
    CustomerID  nchar(5)   REFERENCES Customers(CustomerID),  
    Workstation nchar(30)  NOT NULL DEFAULT HOST_NAME(),  
    OrderDate   datetime   NOT NULL,  
    ShipDate    datetime   NULL,  
    ShipperID   int        NULL REFERENCES Shippers(ShipperID));  
GO
