Connecting to Microsoft SQL Server 7.x, 2000 Use the settings in the following table to connect ColdFusion to Microsoft SQL Server 7.x, 2000 data sources: Setting CF Data Source Name Database Server Port Username Password Description Select Method Description The data source name (DSN) used by ColdFusion to connect to the data source. The database to which this data source connects. The name of the server that hosts the database that you want to use. If the database is local, enclose the word local in parentheses. The number of the TCP/IP port that the server monitors for connections. The user name that ColdFusion passes to the JDBC driver to connect to the data source if a ColdFusion application does not supply a user name-for example, in a cfquery tag. The password that ColdFusion passes to the JDBC driver to connect to the data source if a ColdFusion application does not supply a password-for example, in a cfquery tag. (Optional) A description for this connection. Determines whether server cursors are used for SQL queries. The Direct method provides more efficient retrieval of data when you retrieve record sets in a forward-only direction and you limit your SQL Server connection to a single open SQL statement at a time. This is typical for ColdFusion applications. The Cursor method lets you have multiple open SQL statements on a connection. This is not typical for ColdFusion applications, unless you use pooled statements. Maintain Connections ColdFusion establishes a connection to a data source for every operation that requires one. Enable this option to improve performance by caching the data source connection. Timeout (min) The maximum number of minutes after the data source connection is made that you want ColdFusion to cache a connection after it is used.

Login Timeout (sec) The number of seconds before ColdFusion times out the data source connection login attempt. CLOB Select to return the entire contents of any CLOB/Text columns in the database for this data source. If unchecked, ColdFusion retrieves the amount specified in the Long Text Buffer setting.

Connecting to Microsoft SQL Server 7.x, 2000
Use the settings in the following table to connect ColdFusion to Microsoft SQL Server
7.x, 2000 data sources:
Setting
Description
CF Data Source
Name
The data source name (DSN) used by ColdFusion to connect to the
data source.
Database
The database to which this data source connects.
Server
The name of the server that hosts the database that you want to use.
If the database is local, enclose the word local in parentheses.
Port
The number of the TCP/IP port that the server monitors for
connections.
Username
The user name that ColdFusion passes to the JDBC driver to
connect to the data source if a ColdFusion application does not
supply a user name—for example, in a
cfquery
tag.
Password
The password that ColdFusion passes to the JDBC driver to
connect to the data source if a ColdFusion application does not
supply a password—for example, in a
cfquery
tag.
Description
(Optional) A description for this connection.
Select Method
Determines whether server cursors are used for SQL queries.
The Direct method provides more efficient retrieval of data when
you retrieve record sets in a forward-only direction and you limit your
SQL Server connection to a single open SQL statement at a time.
This is typical for ColdFusion applications.
The Cursor method lets you have multiple open SQL statements on
a connection.
This is not typical for ColdFusion applications, unless
you use pooled statements.
Maintain
Connections
ColdFusion establishes a connection to a data source for every
operation that requires one. Enable this option to improve
performance by caching the data source connection.
Timeout (min)
The maximum number of minutes after the data source connection
is made that you want ColdFusion to cache a connection after it is
used.
Interval (sec)
The time (in seconds) that the server waits between cycles to check
for expired data source connections to close.
Disable Connections
If selected, suspends all client connections.
Login Timeout (sec)
The number of seconds before ColdFusion times out the data
source connection login attempt.
CLOB
Select to return the entire contents of any CLOB/Text columns in
the database for this data source. If unchecked, ColdFusion
retrieves the amount specified in the Long Text Buffer setting.
