[jira] [Updated] (CALCITE-4382) CompileException on table with
array of struct column
[ https://issues.apache.org/jira/browse/CALCITE-4382?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Nathan Hartwell updated CALCITE-4382:
-------------------------------------
Description:
Trying to query a table like this
{code:java}
Table brokenTableWithArrayOfStructs = new EmptyTable() {
@Override
public RelDataType getRowType(RelDataTypeFactory typeFactory) {
return typeFactory.builder()
.add("A", typeFactory.createArrayType(typeFactory.builder().add("foo", SqlTypeName.INTEGER).build(), -1))
.add("B", SqlTypeName.INTEGER)
.build();
}
};{code}
fails; the relevant bit appears to be
{code:java}
Caused by: org.codehaus.commons.compiler.CompileException: Line 5, Column 59: No applicable constructor/method found for actual parameters "java.lang.Object"; candidates are: "public static org.apache.calcite.linq4j.Enumerable org.apache.calcite.linq4j.Linq4j.asEnumerable(java.lang.Iterable)", "public static org.apache.calcite.linq4j.Enumerable org.apache.calcite.linq4j.Linq4j.asEnumerable(java.lang.Object[])", "public static org.apache.calcite.linq4j.Enumerable org.apache.calcite.linq4j.Linq4j.asEnumerable(java.util.List)", "public static org.apache.calcite.linq4j.Enumerable org.apache.calcite.linq4j.Linq4j.asEnumerable(java.util.Collection)"
{code}
Removing column A in the example above so that the array of structs is the only column works, as does defining column B as a map of structs. Full test case and output(including full stack trace and problematic generated code) attached.
