Hi, I am new to calcite. if you can provide any info about the following questions, I would really appreciate it.
I have a RexInpuRef which refers to a column from input schema. 1) how do I find the column name and column position in its input schema? The the input schema is formed by joining two tables, 2) how do I find original column name and original column position in original user-defined table? Do we store any such info in the RefInputRef node itself? Thanks in advance, Dustin
