Problem:

Executing Information Link based on Google BigQuery fails with error "Marshalling Error: INVALID_CHARACTER_ERR: An invalid or illegal XML character is specified."


Solution:

When executing an Information Link based on Google BigQuery using the default template, it may fail to load with the following error: 

Error message: Could not open information link.
ImportException at Spotfire.Dxp.Data:
Failed to execute data source query for data source "Information link". (HRESULT: 80131500)

Quotes (like " ") are appended to the schema, table and column names by default in the Information link query. In Google BigQuery, having quotes '' " in the schema, table and column names in the SQL query is not supported. To resolve, please follow either of the options:

Option 1) Edit the default SQL of the Information Link by removing the quotes to the schema, table and column names. See Editing the SQL of an Information Link for more details. For example, if the default Information Link SQL is: 
SELECT
  B1."ASSISTS" AS "ASSISTS",
  B1."NAME" AS "NAME",
  B1."POSITION" AS "POSITION"
FROM
  "spotfire_demodata"."dbo"."BASEBALL" B1
WHERE
  <conditions>
It should be modified to: 
SELECT
  B1.ASSISTS AS ASSISTS,
  B1.NAME AS NAME,
  B1.POSITION AS POSITION
FROM
   spotfire_demodata.dbo.BASEBALL B1
WHERE
  <conditions>


Option 2) Add the following lines before </jdbc-type-settings> in the default template available for Google BigQuery from the TIBCO Spotfire® JDBC Data Access Connectivity Details wiki page: 
<column-name-pattern>$$name$$</column-name-pattern>
<table-name-pattern>$$name$$</table-name-pattern>
<schema-name-pattern>$$name$$</schema-name-pattern>
<catalog-name-pattern>$$name$$</catalog-name-pattern>
<procedure-name-pattern>$$name$$</procedure-name-pattern>
<column-alias-pattern>$$name$$</column-alias-pattern>
