Microsoft Access Connector

This node creates a connection to a Microsoft Access database file via its JDBC driver. You need to provide the path to the database file. No username and password are required for MS-Access databases.

This node uses the selected driver's JDBC URL template to create the concrete database URL. Field validation in the dialog depends on whether the (included) tokens referencing them are mandatory or optional in the template.

Options

Connection settings

Database Dialect
Choose the registered database dialect here.
Database Driver

Choose the JDBC driver to connect to the database here. If you select "Use latest driver version available" upon execution the node will automatically use the driver with the latest (highest) driver version that is available for the current database type. This has the advantage that you do not need to touch the workflow after a driver update. However, the workflow might break in the rare case that the behavior of the driver e.g. type mapping changes with the newer version.

If this option is not enabled, you can select a specific version of the registered drivers via the drop-down list. Additional drivers can be registered via KNIME's preference page "KNIME -> Databases". For more details on how to register a new driver see the database documentation.

Location
The path to the MSAccess database file. The corresponding driver URL template variable is file.

JDBC Parameters

This tab allows you to define JDBC driver connection parameter. The value of a parameter can be a constant, variable, credential user, credential password or KNIME URL. When dealing with large databases it is necessary to set the JDBC "memory" property to "false". For more information about the supported driver properties see the UCanAccess JDBC driver documentation.

Advanced

This tab allows you to define KNIME framework properties such as connection handling, advanced SQL dialect settings or logging options.

Input Type Mapping

This tab allows you to define rules to map from database types to KNIME types.

Mapping by Name
Columns that match the given name (or regular expression) and database type will be mapped to the specified KNIME type.
Mapping by Type
Columns that match the given database type will be mapped to the specified KNIME type.

Output Type Mapping

This tab allows you to define rules to map from KNIME types to database types.

Mapping by Name
Columns that match the given name (or regular expression) and KNIME type will be mapped to the specified database type.
Mapping by Type
Columns that match the given KNIME type will be mapped to the specified database type.
