Trying to query what ApexClass was used by a CronTrigger by determining what Trigger executed an AsyncApexJob.

The AsyncApexJob shows the Apex Class and if I can query the CronTriggerId that executed that job, I can determine what job was using that Apex Class.

The SOAP API Developer Guide shows that the Metadata for AsyncApexJob has a field for CronTriggerId but when I attempted to query that info, I received an error that the column doesn't exist for CronTriggerId.
