Connecting to other data sources
Use the settings in the following table to connect ColdFusion MX to data sources through JDBC
drivers that do not appear in the drop-down list of drivers:
Login Timeout (sec) The number of seconds before ColdFusion MX 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 not selected, ColdFusion MX retrieves the
number of characters specified in the Long Text Buffer setting.
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
number of characters specified in the BLOB Buffer setting.
LongText Buffer The default buffer size; used if Enable Long Text Retrieval (CLOB) is not
selected. The default value is
64000
bytes.
BLOB Buffer The default buffer size; used if the BLOB option is not selected. The
default value 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.
JDBC URL The JDBC connection URL for this data source.
Driver Class The fully qualified class name of the driver. For example,

directory defined in the ColdFusion classpath.
Driver Name (Optional) The name of the driver.
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 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.
Connection String A field that passes database-specific parameters, such as login
