Ulrich Kramer commented on CALCITE-4188:
----------------------------------------
I also created a PR for this issue: https://github.com/apache/calcite/pull/3562
I had overlooked this ticket here.
The main difference between the two PR is how correlation variable are handled:
- 3562 uses an offset of 10000 to put the correlation variables into the
DataContext
- 2116 uses an enum to distinguish between correlation variables and dynamic
variables, which is the more robust way.
