Zoltan Haindrich created CALCITE-3215: -----------------------------------------
Summary: Simplification may not fully simplify IsNotNull expressions Key: CALCITE-3215 URL: https://issues.apache.org/jira/browse/CALCITE-3215 Project: Calcite Issue Type: Bug Reporter: Zoltan Haindrich Assignee: Zoltan Haindrich CALCITE-2929 have added a safety check to avoid simplifying problematic cases. The safety check apparently misses some kinds, for example: {{UNARY_PLUS}} {code} @Test public void testIsNullSimplificationWithUnaryPlus() { RexNode expr = isNotNull(coalesce(unaryPlus(vInt(1)), vIntNotNull(0))); RexNode s = simplify.simplifyUnknownAs(expr, RexUnknownAs.UNKNOWN); assertThat(expr.isAlwaysTrue(), is(true)); assertThat(s, is(trueLiteral)); } {code} -- This message was sent by Atlassian JIRA (v7.6.14#76016)
