Jay Narale created CALCITE-4875: ----------------------------------- Summary: NVL Function Incorrectly changes nullability field of its operands Key: CALCITE-4875 URL: https://issues.apache.org/jira/browse/CALCITE-4875 Project: Calcite Issue Type: Bug Components: core Reporter: Jay Narale
We rewrite the NVL function in _org/apache/calcite/sql2rel/StandardConvertletTable.java:303_ , during the rewrite we currently override the operands' nullability to be NOT NULL which is not needed. This causes issues if that operand is pushdown , since the input of that operand need not be not nullable whereas we forced that operand to be Not nullable -- This message was sent by Atlassian Jira (v8.3.4#803005)
