Description
Overloaded user-defined functions that have Double and BigDecimal arguments will goes wrong. We add the following udf method in Smalls.AllTypesFunction:
public double toDouble(BigDecimal var) { return var.doubleValue(); } public double toDouble(Double var) { return var; }
when test it :
@Test public void testBigDecimalAndLong() { final CalciteAssert.AssertThat with = withUdf(); with.query("values \"adhoc\".\"toDouble\"(cast(1.0 as double))") .returns("EXPR$0=1.0\n"); }
where price is a double value in table tb, exception occurs:
