Julian Hyde created CALCITE-445:
-----------------------------------
Summary: Pull up filters rejected by a ProjectableFilterableTable
Key: CALCITE-445
URL: https://issues.apache.org/jira/browse/CALCITE-445
Project: Calcite
Issue Type: Bug
Reporter: Julian Hyde
Assignee: Julian Hyde
Suppose that {{t (i, j, k)}} is a table that implements
ProjectableFilterableTable, we execute the query {{select k from t where j =
1}}, and {{t}} refuses to evaluate the filter {{j = 1}}.
We should still push the project to the table. But we need to project the extra
column, {{j}} needed by the filter, and transform it, because it now occurs
after the project.
