HOST_ID (T-SQL)

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))
