-------------------------------------
Summary: RelToSqlConverter does not support
LogicalTableFunctionScan
Key: CALCITE-3354
URL: https://issues.apache.org/jira/browse/CALCITE-3354
Project: Calcite
Issue Type: Bug
Affects Versions: 1.21.0
Reporter: Anton Haidai
Here is the test in *RelBuilderTest* to reproduce the isse (the right place for
this test is RelToSqlConverterTest, but it does not have test table functions
configured):
{code}
@Test
public void testFailToConvertLogicalTableFunctionScanToSql() {
final RelBuilder builder = RelBuilder.create(config().build());
final SqlOperator rampFunction = new MockSqlOperatorTable.RampFunction();
RelNode root = builder.functionScan(rampFunction, 0, builder.literal(3))
.build();
toSql(root, CalciteSqlDialect.DEFAULT);
}
private static String toSql(RelNode root, SqlDialect dialect) {
final RelToSqlConverter converter = new RelToSqlConverter(dialect);
final SqlNode sqlNode = converter.visitChild(0, root).asStatement();
return sqlNode.toSqlString(dialect).getSql();
}
{code}
Result:
{code}
