The default generated SQL in a Spotfire information link uses Oracle syntax “(+)” to indicate joins. Not all database engines support this syntax.
Issue/Introduction
Resolution
Add this setting to <jdbc-type-settings> in the XML for your Teradata data source template in Spotfire:
<use-ansii-style-outer-join>true</use-ansii-style-outer-join>
If a setting that reads <use-ansii-style-outer-join>false</use-ansii-style-outer-join> already exists in the data source template, edit it to read as follows:
<use-ansii-style-outer-join>true</use-ansii-style-outer-join>
Background:
------------------
The table entry for use-ansii-style-outer-join in the table of available data-source-template XML settings in the Spotfire Server Installation and Configuration Manual notes that
----------------------------------------------------------------------------------------
'The default generated SQL uses the Oracle way with “(+)” to indicate joins. If this setting is set to true an attempt is made to rewrite it to standard ANSII format, making it possible to run on non-Oracle databases' that do not support this syntax.
----------------------------------------------------------------------------------------
The default value for this setting is False, but you can change a data source template to make it use ANSI style outer joins. After you have made this change and restarted the server, log into Spotfire Server from the Spotfire Professional desktop client once more. If the information link does not work now try creating a new, identical information link to see if the change takes effect then.
