Haisheng Yuan created CALCITE-3492: -------------------------------------- Summary: Exception thrown when terms has 1 RexNode in RexUtil.simplifyOrs() Key: CALCITE-3492 URL: https://issues.apache.org/jira/browse/CALCITE-3492 Project: Calcite Issue Type: Improvement Components: core Reporter: Haisheng Yuan
This is a regression caused by the refactoring in 1.20.0. When {{terms}} has only 1 element, it will throw an exception. We discovered the issue when trying to upgrade Calcite. {code:java} public static RexNode simplifyOrs(RexBuilder rexBuilder, List<RexNode> terms) { return new RexSimplify(rexBuilder, RelOptPredicateList.EMPTY, EXECUTOR) .simplifyUnknownAs(rexBuilder.makeCall(SqlStdOperatorTable.OR, terms), RexUnknownAs.UNKNOWN); } {code} We can't assume the {{terms}} always has more than 1 element. Although this method is deprecated, I think we need to correct the regression. Maybe we don't need a test case, given it is a deprecated method. -- This message was sent by Atlassian Jira (v8.3.4#803005)
