thankd you @rednaxelafx your sharing is always good enough. My origin requirement is finding a way which behavior is similar with `BlockExpression`, the name `delegate` is just a alias. I see what you worried about, it may make plan and expression fuzzy that's we don't expect. "local alias" to me more like a udf but we build it in SQL directly, not sure it's accpted since it introduces some complex. Besides, the idea enhancements the Catalyst sounds excited to me, I'd like to do this. Maybe I need sometime to think about it. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
