Jess Balint created CALCITE-1595: ------------------------------------ Summary: NPE in SqlTypeUtil Key: CALCITE-1595 URL: https://issues.apache.org/jira/browse/CALCITE-1595 Project: Calcite Issue Type: Bug Components: core Reporter: Jess Balint Assignee: Julian Hyde Priority: Minor
I have some RelBuilder code building an expression something like {{+(+($0, "30"), "30")}}. Yes, they are string literals :) This results in an NPE as the type of {{+($0, "30")}} is _null_ and it hits the following code: {code} public static boolean isExactNumeric(RelDataType type) { SqlTypeName typeName = type.getSqlTypeName(); if (typeName == null) { return false; } switch (typeName) { {code} Here's the stack: {noformat} at org.apache.calcite.sql.type.SqlTypeUtil.isExactNumeric(SqlTypeUtil.java:414) at org.apache.calcite.rel.type.RelDataTypeFactoryImpl.createDecimalQuotient(RelDataTypeFactoryImpl.java:521) at org.apache.calcite.sql.type.ReturnTypes$7.inferReturnType(ReturnTypes.java:464) at org.apache.calcite.sql.type.SqlTypeTransformCascade.inferReturnType(SqlTypeTransformCascade.java:54) at org.apache.calcite.sql.type.SqlReturnTypeInferenceChain.inferReturnType(SqlReturnTypeInferenceChain.java:56) at org.apache.calcite.sql.SqlOperator.inferReturnType(SqlOperator.java:469) at org.apache.calcite.rex.RexBuilder.deriveReturnType(RexBuilder.java:271) at org.apache.calcite.rex.RexBuilder.makeCall(RexBuilder.java:245) at org.apache.calcite.tools.RelBuilder.call(RelBuilder.java:529) {noformat} Where would be an appropriate place to add a new test for this? I'll get a PR for this and the other stuff created soon. Thx. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
