The query ...

Select...
From ...
Join ...
Group By ...
From ...

... is malformed. You can't just daisy-chain From clauses. If there must be multiple From clauses, they need to be in parenthesised subqueries.

And, the query doesn't aggregate so what's the purpose of the Group By clauses following each Select...From block?

We can't just make up syntax. The query needs a rewrite.
