Can someone please tell me what this previously-written SQL is doing?
I don't understand how it is structured. I'm familiar with JOINs such
as this (1 joined table per 1 ON phrase):
FROM t1
LEFT OUTER JOIN t2 ON t1.id = t2.id
LEFT OUTER JOIN t3 ON t2.name = t3.name
But the following SQL is puzzling me. To which JOINs are the ON
phrases connected?
Any help would be appreciated! (Feel free to re-format the physical
structure of the lines....as this is the way it came to me!)
