Connecting to Microsoft SQL Server 7.x, 2000 47
Connecting to Microsoft SQL Server 7.x, 2000
Use the settings in the following table to connect ColdFusion MX to Microsoft SQL Server 7.x,
2000 data sources:
BLOB Select to return the entire contents of any BLOB/Image columns in the
database for this data source. If not selected, ColdFusion MX retrieves
the amount specified in the Blob Buffer setting.
LongText Buffer The default buffer size, used if Enable Long Text Retrieval(CLOB) is not
selected. Default is 64000 bytes.
BLOB Buffer The default buffer size, used if Enable binary large object retrieval (BLOB)
is not selected. Default is 64000 bytes.
Allowed SQL The SQL operations that can interact with the current data source.
Setting Description
CF Data Source Name The data source name (DSN) used by ColdFusion MX 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 MX 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 (16-character limit) that ColdFusion MX 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.
Limit Connections Specifies whether ColdFusion MX limits the number of database
connections for the data source. If you enable this option, use the Restrict
Connections to field to specify the maximum.
Restrict Connections to Specifies the maximum number of database connections for the data
source. To use this restriction, you must enable Limit Connections.
