HOST_ID ( )
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.
This example creates a table that uses HOST_ID() in a DEFAULT definition to record the terminal ID of computers that insert rows into a table recording orders.
CREATE TABLE Orders (OrderID INT PRIMARY KEY, CustomerID NCHAR(5) REFERENCES Customers(CustomerID), TerminalID CHAR(8) NOT NULL DEFAULT HOST_ID(), OrderDate DATETIME NOT NULL, ShipDate DATETIME NULL, ShipperID INT NULL REFERENCES Shippers(ShipperID)) GO
