How do you determine the article ID from the long guid filename format?

Question

It would be very useful sometimes to determine the article Id number from the guid name or to get the guid name from the
article ID number.
Sometimes a log error references a guid name. Which isn't too bad because you can go to the distribution point and look through the folders and or install the contents.
The other way around, finding a specific update from a list of guid number folders can be a bit of a job.

I put together this SCCM admin console query:
I set the Querys object Type :  <unspecified>  
 then I pasted in this:
SELECT SMS_SoftwareUpdate.ArticleID,
SMS_SoftwareUpdate.BulletinID
  FROM SMS_CIToContent
  INNER JOIN SMS_SoftwareUpdate
  ON SMS_CIToContent .CI_ID =SMS_SoftwareUpdate.CI_ID
Where SMS_CIToContent.ContentUniqueID =##PRMMS_CIToContent.ContentUniqueID##
I patched this together from several sources, but was largly able to retain my ignorance about the how and whys of
Extended WQL and its join syntax. It seems very similar to SQL, (from which its derived, I'm told), but you can't just type in SQL code and expect it to work.
I thought you might know of a media source for learning and using  WQL and Extended WQL?
