makes that remote server the current server for the session. The local server in effect enters a pass-through mode, sending all SQL statements to the remote server. The remote database can now be processed directly over the connection, with standard, unmodified queries and data manipulation statements: Get the names and sales numbers of all salespeople who are already over quota.

ends the pass-through mode, and the local server once again becomes the current server. Except for the CONNECT/DISCONNECT statement pair, the mechanism for managing remote access is external to the SQL language. The database administrator tells the local database about the existence, locations, and names of remote servers through the spaddserver() and spdropserver() system stored procedures. The current local user name and password are used by default for access to the remote server. Alternatively, the database administrator can specify a proxy user name/password that is used for remote server access, again through system stored procedures. Sybase ASE offers other, more complex distributed database capabilities, but this basic capability has the advantage of maximum simplicity. Oracle takes a somewhat different approach to remote database access, but one that is similar to the capabilities provided by other DBMS brands. It requires that Oracle s SQL*Net networking software be installed along with the Oracle DBMS on both the local and the remote system. The database administrator is responsible for establishing one or more named database links from the local database to remote databases. Each database link specifies Network location of the target remote computer system Communications protocol to use

Name of the Oracle database on the remote server Remote database user name and password All remote database access occurs via a database link and is governed by the privileges of the supplied user name in the remote system. The database link thus embodies the answers to the which database, how to communicate, and what privileges questions raised earlier in this section. The database administrator assigns the database link a name. Links can be private (created for use by a specific user of the local system) or public (available for use by multiple users of the local system). To access a remote database over a database link, the local system user uses standard SQL statements. The name of the database link is appended to the remote table and view names, following an at sign (@). For example, assume you are on a local computer system that is connected to a copy of the sample database on a remote system over a database link called CENTRALHOST. This SQL statement retrieves information from the remote SALESREPS table: Get the names and sales numbers of all salespeople who are already over quota.

Oracle supports nearly all of the query capabilities that are available for the local database against remote databases. The only restriction is that every remote database entity (table, view, etc.) must be suffixed with the database link name. Also, Oracle does not support DDL or database updates via a database link. Here is a two-table join, executed on the remote Oracle database: Get the names and of ce cities of all salespeople who are already over quota.
SELECT FROM WHERE AND NAME, CITY, QUOTA, SALES SALESREPS@CENTRALHOST, OFFICES@CENTRALHOST SALES > QUOTA REP_OFFICE = OFFICE;
Informix Universal Server provides capabilities that are similar to those offered by Oracle, but uses a different mechanism for identifying remote databases, and a different SQL syntax extension. The Informix architecture differentiates between a remote database server and a remote database that is managed by the remote server, since it tends to provide rich support for multiple, named databases per server. Suppose an Informix copy of the sample database is called SAMPLE, and it resides on a remote database server called CENTRALHOST. Then this query is equivalent to the previous Oracle and Sybase examples: Get the names and sales numbers of all salespeople who are already over quota.
SELECT NAME, QUOTA, SALES FROM SAMPLE@CENTRALHOST:SALEREPS WHERE SALES > QUOTA;
