Connecting to Microsoft Access
Use the settings in the following table to connect ColdFusion MX to Microsoft Access data
sources:
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
amount 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
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.

locate and enter a database that contains database security information.
The system database is usually located in winnt\system32\system.mdw.

requesting a connection. The Microsoft Access driver uses the default
user name and password. (specified in Advanced Settings).
ColdFusion 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.
ColdFusion 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.
Page Timeout The time (in tenths of a second) before a request for a ColdFusion page
times out.
Max Buffer Size The total number of bytes that ColdFusion MX uses to cache application
pages. Enter a value to optimize ColdFusion performance.
Connection String A field that passes database-specific parameters, such as login
credentials, to the data source.
Default Username The user name that ColdFusion MX passes to the JDBC driver to connect
