Danny Chan commented on CALCITE-3065:
-------------------------------------
Thanks [~Aron.tao], i do not have strong willingness for Calcite to support
primitive numeric type for method SqlLiteral#getValueAs, because in our code
base, we do not have use cases like you did:
{code:java}
val tp = new JavaTypeFactoryImpl(RelDataTypeSystem.DEFAULT)
literal.getValueAs(tp.getJavaClass(literal.getType).asInstanceOf[java.lang.Class[_]])
{code}
So, what i'm curious and confused about is why you need the "true" typed value
of the literal ? I think you should give us a persuasive reason, after all,
Calcite is for all kinds of engines and use cases, we should not add a logic
that is not common and not used even for Calcite itself.
