Julian Hyde commented on CALCITE-2303:
--------------------------------------
We (the Calcite community) didn't choose to follow a different standard than
Dremio. We just didn't notice that our view of the standard is wrong.
Why? Because we don't have anyone in the community actively working on ODBC
compatibility tests.
Actually, we do. You guys. When you write tests or code, please push them
upstream. Then we'll be in sync, and we won't need extra engineering effort to
deal with drift.
