Hi [~danny0405]
you mean literal.getType? *SqlTypeName typeName* is Integer, from the first
coommet, I didn't argue that.
But the value of RexLiteral is decimal, so I do
this:*literal.getValueAs(Otherwise why exists this method)*.
code from previous comment:
val tp = new JavaTypeFactoryImpl(RelDataTypeSystem.DEFAULT)
literal.getValueAs(tp.getJavaClass(literal.getType).asInstanceOf[java.lang.Class[_]])
*literal.getType ->* INTEGER
*tp.getJavaClass*(*INTEGER*) -> int
literal.getValueAs does not process `int` scenario.
I didn't get your point, hope to hear your voice.
Thanks.
