> If > 1 row on source side matches the same row on target side that means that
> we are forced update (or delete) the same row in target more than once as
> part of the same SQL statement. This should raise an error per SQL Spec
> ISO/IEC 9075-2:2011(E)
> Section 14.2 under "General Rules" Item 6/Subitem a/Subitem 2/Subitem B
> There is no sure way to do this via static analysis of the query.
> Can we add something to ROJ operator to pay attention to ROW__ID of target
> side row and compare it with ROW__ID of target side of previous row output?
> If they are the same, that means > 1 source row matched.
> Or perhaps just mark each row in the hash table that it matched. And if it
> matches again, throw an error.
