Summary: Getting java.lang.NullPointerException at
org.apache.calcite.schema.Schemas.queryable(Schemas.java:211)
Key: CALCITE-3624
URL: https://issues.apache.org/jira/browse/CALCITE-3624
Project: Calcite
Issue Type: Bug
Reporter: anjali shrishrimal
I am creating a RelNode using RelBuilder.
@Test
public void testRun() throws Exception {
FrameworkConfig frameworkConfig = config().build();
final RelBuilder builder = RelBuilder.create(frameworkConfig);
String[] name = new String[]\{"ITEM", "ITEM"};
RelNode scan = builder.scan(name).build();
TranslatableTable items =
(TranslatableTable)frameworkConfig.getDefaultSchema().getSubSchema("ITEM").getTable("ITEM");
scan = items.toRel(ViewExpanders.simpleContext(scan.getCluster()),
scan.getTable());
RelNode level0RelNode =
builder.push(scan)
.filter(
builder.call(SqlStdOperatorTable.AND,
builder.call(SqlStdOperatorTable.EQUALS, builder.field("ITEM_ID"),
builder.literal("AM_TestItem_21Aug17_0614")),
builder.call(SqlStdOperatorTable.EQUALS, builder.field("OBJECT_TYPE"),
builder.literal("Item"))
)
).build();
System.out.println(level0RelNode);
try (PreparedStatement preparedStatement = RelRunners.run(level0RelNode)) {
System.out.println("------------------------");
System.out.println(preparedStatement.toString());
System.out.println("------------------------");
String s = CalciteAssert.toString(preparedStatement.executeQuery());
System.out.println("------------------------");
System.out.println(s);
}
public static Frameworks.ConfigBuilder config() {
CalciteSchema rootSchema1 = CalciteSchema.createRootSchema(true);
rootSchema1 = rootSchema1.add("ITEM", new MySchema());
// MySchema consists of Map of MyTable which extends AbstractQueryableTable
and implements TranslatableTable
return Frameworks.newConfigBuilder().defaultSchema(rootSchema1.plus());
}
