• SQL Server 2000 sends and receives messages by establishing a connection

with mail servers.

• SQL Mail is the mail service of SQL Server 2000 that sends messages to

mailboxes and e-mail pagers using the Transact-SQL commands and

xp_sendmail extended stored procedure.

• You can also create a scheduled job for automatic process of e-mail.

• The following table lists the SQL Mail stored procedures and their description:

Finds the next message in the SQL Server inbox for processing xp_findnextmsg

Deletes specified messages xp_deletemail

Processes queries as an incoming messages and sends the result set to the designated recipients as an outgoing message

• SQLAgentMail is the mail service of SQL Server 2000 that is used for SQL

Server Agent services.

• Before configuring SQL Mail and SQLAgentMail, you need to install MAPI clients

on the SQL Server 2000 computer.

• Linked server is a component of SQL Server 2000 that links multiple database servers to facilitate exchange of information.

2000 supports XML for exchange of information across platforms SQL Server 2000 also provides features for accessing databases through Internet servers, such as IIS

To take advantage of all these features, you need to configure the following

components:

„SQL Mail

„SQLAgentMail

„Linked Server

„SQL Server XML support in IIS

SQL Server 2000 sends and receives messages by establishing a connection with mail servers SQL Server 2000 supports mail servers such as, Microsoft Exchange Server, Microsoft Windows Mail, or Post Office Protocol 3 (POP3) The mails are sent and received using two separate services, SQL Mail and SQLAgentMail Both these services require Messaging Application Programming Interface (MAPI) client applications, such

as Microsoft Outlook and MAPI messaging profile on SQL Server 2000 computer

MAPI is an interface of Microsoft Windows program that enables you to send and receive e-mail within Windows application The services also require Windows NT 4.0

or Windows 2000 domain user account to logon to an instance of SQL Server 2000

SQL Mail

SQL Mail is the mail service of SQL Server 2000 that sends messages to mailboxes

and e-mail pagers using the Transact-SQL commands and xp_sendmail extended

stored procedure It receives and processes mails from a mail system and sends the query response to the designated mail account by creating a reply mail You can use a result set from a query, a message string, a Transact-SQL statement, or a page for an electronic pager as the content of an e-mail message For example, consider the following statements:

EXEC xp_sendmail ‘Scott@Macaluminium.USA’,

@subject = ’Database Login Information’,

@query = ‘Select * from master.dbo.master’

The Transact-SQL statement in the preceding example is a part of the content of the e-mail message You can also create a scheduled job for automatic process of e-mail The following table lists the SQL Mail stored procedures and their description:

xp_sendmail Sends e-mail messages from Transact-SQL batches,

scripts, triggers, and procedures to the designated user

xp_readmail Reads the message

xp_startmail Starts the session of SQL Mail

xp_stopmail Stops the session of SQL Mail

xp_deletemail Deletes specified messages

xp_findnextmsg Finds the next message in the SQL Server inbox for

processing

SQLAgentMail

SQLAgentMail is the mail service of SQL Server 2000 that is used for SQL Server

Agent services SQL Server Agent services are server components that run scheduled

SQL Server 2000 administrative tasks SQLAgentMail is used to send e-mail

notifications to the designated users when any scheduled task, such as database backup or recovery, succeeds or fails You can configure SQLAgentMail to send SQL Server alerts when specific event occurs For example, you can use SQLAgentMail to send an alert to the operators when a particular database event needs immediate action SQLAgentMail uses its own mail profile and domain account These mail profiles and domain accounts are different from that of SQL Mail

Prerequisite for Configuring SQL Mail and

Apart from stored procedures, triggers and alerts can also be coded to send messages using the SQL Mail system

Linked Server

Linked server is a component of SQL Server 2000 that links multiple database servers

to facilitate exchange of information Using this component you can connect or link multiple database servers, such as Oracle, and Microsoft Access using OLEDB data source and OLEDB data providers While you configure the linked server, you need to register the connection and data source information of the OLEDB data source with SQL Server 2000 After successful registration, you can always refer the data source with a single logical name Besides database servers, you can also link SQL Server

2000 database to a text file or a spreadsheet, as shown in the following figure:

You can create and configure the linked server, using SQL Server 2000 Enterprise Manager You can also create and configure a linked server using the

sp_addlinkedserver system stored procedure

SQL Server XML Support in IIS

SQL Server 2000 supports XML to convert an SQL Server 2000 instance into an XML enabled database server With the help of XML enabled database server, you can present the data on the web as XML pages in response to HTTP queries The

generated XML page can be used for exchanging information across different

platforms and organizations To do this, you need to configure IIS virtual directory The configured IIS virtual directory creates an association with the instance of SQL Server 2000 server that enables access to SQL Server 2000 database objects, such as tables through (Hypertext Transfer Protocol) HTTP In addition, you can also access the XML document consisting of one or more SQL statements

Additional Inputs

Using URL to Access SQL Server 2000

You can access SQL Server 2000 using the Uniform Resource Locator (URL) over the Hyper Text Transfer Protocol (HTTP) Using the URL you can:

1 Directly access the database objects, such as tables, view, or triggers of a SQL Server 2000 database However, this is not recommended due to security reasons

2 Execute the XML files containing Transact-SQL statements, known as
