Description

Library path

Shows the path to the data connection if it has been previously saved to the library.

Enable cascading filters for any in-database data tables from this connection

[Only applicable if one or more data tables in the connection are configured for in-database loading.]

Select this check box to enable cascading filters for any in-database data tables in the selected connection, making the filters work more similar to the way filters work in imported data tables.

When cascading filters are enabled, the values displayed in filters are dependent on any other filter selections you have made. Only relevant values are available, and any values that have already been filtered out by filter selections in other filters are not displayed.

Caution: Enabling the cascading behavior for filters for in-database data tables results in an additional query load on the external data source. It is the user's responsibility to ensure that the external data source can handle the extra query load.

Manually add columns for table visualizations

[This option only affects in-database data tables from the selected connection.]

Determines whether to include and show all columns, when you create a new table visualization of an in-database data table in the connection.

By default, this option is cleared. When you create a new table visualization, all columns in the data table are selected and shown in the visualization.

When you select this option, new table visualizations are empty. You must manually select what columns to show in the visualization. To select columns, open the Data in analysis flyout and drag-and-drop the columns to the visualization. You can also select columns in the Visualization properties dialog.

Note: This option also affects the Details-on-Demand. To select columns manually, right-click the Details-on-Demand and select Properties. In the Properties dialog, go to the Columns tab.

Enable caching of data retrieved from this connection

 

No, always get fresh data from the external source

Use this option if you do not want to cache data from the data connection. Note that it can put a very high load on the database server to always get fresh data if many users are working with data from the same server simultaneously.

Yes, but let the cached data expire after

Use this option to cache data from the data connection, but to refresh if the cached data is older than the specified time limit.

Yes, but let the cached data expire every [day or day of the week] at [time]
 

Use this option to cache data from the data connection, but to refresh once every day or on a specified day every week, at the specified time.

Share cached data between all concurrent users of the Spotfire web client

Select this check box if you want to share the cached data for the data connection.

Note: If the external data source has been set up so that the data available for each user depends on who you are, then you should not allow sharing of cached data.
