      Description

      RewritePredicateSubquery rewrites correlated subquery to join operations. During the structural integrity, I found {[RewritePredicateSubquery}} can produce unresolved query plans due to conflicting attributes. We should not let RewritePredicateSubquery produce unresolved plans.
