SQL Oracle LEFT JOIN and SUBQUERY error: ORA-00905: missing keyword
Asking for your help on this Oracle query. It's giving me the error 2 "ORA-00905: missing keyword". It was working fine before I added the LEFT JOIN statement. Obviously it won't deliver the information as we need it without the LEFT JOIN statement.
Please provide any help to know which keyword is missing in this query
Thanks a lot!:

In Oracle we don't include the AS
when declaring a table alias. Instead of
) AS TABLE_RESOLVERS
write
) TABLE_RESOLVERS
This is one example when Oracle syntax is more restrictive than some other flavours of SQL. It is also inconsistent with the declaration of column aliases, which is unfortunate but almost certainly it's too complex to change this far down the road.
It seems like the "AS" is extraneous near "AS TABLE_RESOLVERS"
