Designating a Teradata connector property as overridable in the QueryGrid portlet allows you to override configured Teradata connector properties when starting queries during an individual processing session.
When you override a Teradata connector property, the servername in the syntax statement indicates the foreign server the listed and overridable Teradata connector properties apply. The designated foreign server uses the value of the properties listed in the syntax statement until the occurrence (if any) of another servername.
