Summary: RexSimplify.removeNullabilityCast() always removes cast for operand with ANY type Key: CALCITE-2069 URL: https://issues.apache.org/jira/browse/CALCITE-2069 Project: Calcite Issue Type: Bug Reporter: Volodymyr Vysotskyi Assignee: Julian Hyde When a field is received from Dynamic Table, its type left {{ANY}}, and it is used in the filter condition with the cast, which actually should produce physical cast (for example we are trying to cast varchar to boolean) {{RexSimplify.removeNullabilityCast()}} removes this cast and lefts only field in condition. This test helps to observe this issue: {code:java} @Test public void testFilterCastAny() { final RelBuilder builder = RelBuilder.create(config().build()); final RelDataType intType = builder.getTypeFactory().createSqlType(SqlTypeName.ANY); RelNode root = builder.scan("EMP") .filter( builder.cast( builder.patternField("varchar_field", intType, 0), SqlTypeName.BOOLEAN)) .build(); assertThat(str(root), is("LogicalFilter(condition=[CAST(varchar_field.$0):BOOLEAN NOT NULL])\n" + " LogicalTableScan(table=[[scott, EMP]])\n")); } {code} It happens because {{SqlTypeUtil.equalSansNullability()}} returns true if any of its arguments has {{ANY}} type. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
