How do we know if we have any rows in a table? We use the COUNT function to return a count of the number of rows in a table. If you enter Listing into Query Analyzer we can check the data insert for the Spy table.
This will return the current number of rows (well actually […]
The introduction of SQL Server 2000 enables us to have multiple instances of SQL Server running on a single machine. In the past we only had one instance of SQL Server, which in SQL Server 2000 is called the Default instance. Now we can have as many named instances as we want. Microsoft has tested […]
User-defined functions (UDFs) rock! UDFs allow us to create compliant units of Transact-SQL that can return either a scalar value or a table.
A scalar value returns a single value (as our UDF did) of the type we specify in the CREATE FUNCTION statement.
A table returns a table of results. It leverages the new data type […]

Although the Internet protocol is the second component of the TCP/IP acronym, it is perhaps the more important of the two. IP is the basic protocol in the suite that provides the information used for getting packets from one place to another. IP provides a connectionless, unacknowledged network service, and also provides the addressing mechanism […]
IP addresses are divided into three major classes (A, B, and C) and two less familiar ones (D and E). Each class uses a different portion of the IP address bits to identify the network. There is a need for classifying networks because there is a need to be able to create networks of different […]
Because it is usually implemented in a read-only memory (ROM) chip, the BOOTP protocol client is a simple, concise bit of code. The exchange of UDP messages between the client and the BOOTP server consists of a series of requests and replies. The same packet format is used for both types of messages with an […]

Installing a DHCP server on Windows 2000 or Windows 2003 Servers is just as simple as most application installs. However, you’ll need to have some information ready before you begin the installation. You will need to know the range of addresses that the server will administer and lease to clients. If you have any servers […]
The Windows 2000/2003 DHCP servers provide support for BOOTP clients. The Default BOOTP user class of options is used to configure the information that is supplied to these clients. Although standard BOOTP servers require that the server be configured in advance with a table of client hardware addresses and corresponding IP addresses, Windows 2000/Server 2003 […]
Many options that can be used for BOOTP and DHCP clients were discussed. The Windows 2000/2003 DHCP service enables you to configure which options will be offered to clients of the service. To configure the options, expand the MMC tree of DHCP servers to locate the server you want to manage. Click that server to […]
