If any joins have been specified between the tables currently used in the information link, clicking this button will automatically add one or more suitable joins to the Selected joins list. If a default join has been specified, then this join will be used if possible.

Join data source

If more than one join database have been defined during the setup of the server, then you can select where the joining should take place here.

id_create_information_link_tab_prompts.png

Note: Prompts may be converted to on-demand parameters if the prompted information link is added to an analysis from the Add Data Tables dialog. This is done by clicking on the Use-On Demand button when a prompt step is shown. Any required parameters must then be specified in the On-Demand Settings dialog instead.

Option

Description

Column

The names of added columns to prompt.

Prompt Type

Select what kind of selections should be available in the prompt when the link is opened.

Values lets you enter your own list of values to include. This prompt type should only be used if all end users of the information link know which values are valid for the column.

Range lets you specify a range of values. This prompt type is suitable for numerical or Date/DateTime/Time columns when a sustained range of numbers or time periods are to be retrieved.

Multiple selection presents a list of available values from which you can select multiple values. This type of prompt can be used even if the end users of the information link have no previous knowledge of the data.

Single selection presents a list of available values from which you can select a single value only. This type of prompt can be used even if the end users of the information link have no previous knowledge of the data.

See also Details on Open Information Link.

Mandatory

Select this check box to make it mandatory to select values in the prompt. It is not possible to clear the check box if Single selection has been chosen.

For non-mandatory prompts the end user can leave the prompt step dialog untouched in order to retrieve all data for that step.

Max Selections

Type the maximum number of selections allowed. It is not possible to specify a maximum number of selections if Single selection or Range has been chosen.

Add

Opens the Add Column dialog where you can select a column on which to add a prompt.

Remove

Removes the selected column from the Prompts section.

Move Up

Click to move an element up. This is used to control the order of the columns with prompts. Filter elements are always applied before prompts regardless of order.

Move Down

Click to move an element down.

Groups...

Opens the Prompt Groups dialog where you can specify different prompt groups for different prompts, making elements independent from each other. This is used to improve the performance of information links when retrieving data from STAR schema databases. See Using Prompt Groups for more information.

 

id_create_information_link_tab_conditioning.png

Option

Description

None

If a parameter is not listed even after clicking Refresh, you may have created a parameter containing unsupported characters. See Parameterized Information Links for more information. It is also possible that you have edited the SQL of the information link. In that case, the altered SQL code overrides the parameters settings in the user interface.

Data Type

id_create_information_link_tab_caching.png

Option

Description

Cacheable

Select this check box to allow caching of the information link. Caching  the results of an information link can improve the performance when executing information links that return non-volatile data (especially when the TIBCO Spotfire Server is situated far away from the data source).

Note: The information link should not be set as cacheable if the result of the information link is personalized or depending on things beyond the control of Information Services (for example, database row level security).

Timeout (seconds)

Allows you to specify a timeout limit for how long the cached data should be valid. When the limit has expired, the information link in the cache is no longer valid so the results will be fetched from the data source again the next time the information link is opened.

Validation data source

If your information link contains data from more than one data source you can select on which data source the validation query specified below should be run.

Validation SQL query

Allows you to provide a SQL query which gets executed when the result is added to the cache and each time it is later retrieved. The underlying data will be considered to be unchanged if the output is the same as the first time the query was executed. The SQL query should return 0 or 1 row containing a single column. An example could be:

select count(1) from TABLE
