HOST_ID

Returns the workstation identification number.

Syntax

HOST_ID ( )

Return Types

char(8)

Remarks

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.

Examples

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
