# Proposed changes Issue Number: close #7929 ## Problem Summary: The tuple ids of the empty set node must be exactly the same as the tuple ids of the origin root node. In the issue, we found that once the tree where the root node is located has a window function, the tuple ids of the empty set node cannot be calculated correctly. This pr mostly fixes the problem. In order to calculate the correct tuple ids, the tuple ids obtained from the SelectStmt.getMaterializedTupleIds() function in the past are changed to directly use the tuple ids of the origin root node. Although we tried to fix #7929 by modifying the SelectStmt.getMaterializedTupleIds() function, this method can't get the tuple of the last correct window function. So we use other ways to construct tupleids of empty nodes. ## Checklist(Required) 1. Does it affect the original behavior: (Yes/No/I Don't know) 2. Has unit tests been added: (Yes/No/No Need) 3.
