H2 Connector (legacy)

Options

Path

The path to the H2 database file.

Timezone correction

Select the TimeZone to convert the date, time or timestamp field into. The current implementation can't represent time zones. In order to support persisting those fields into a database, the time values can be changed according to the selected time zone, which is used as the offset (including the daylight saving time) for the original values:

• No correction (use UTC) is used for workflows (created before 2.8) and doesn't apply any correction,
• Use local timezone uses the local time zone offset to correct the date field before reading or writing, and
• Use selected timezone allows selecting the time zone to covert the date values into.

Allow spaces in column names

Check this option if the database can handle spaces in column names. Otherwise KNIME will replaces them by underscores.

Validate connection on close

Check this option if you want to validate the connection when closing the dialog.

Retrieve metadata in configure

This option controls subsequent nodes. Usually when a database node is configured it retrieves the metadata of the current table or query from the database for usage in subsequent nodes. If metadata retrieval takes quite some time it will slow down workflow configuration and execution noticeably, especially since metadata is retrieved in both configure and execute. In such cases it's better to switch this option off and only retrieve metadata during execute.
