> In TyepCheckProcFactory.NumExprProcessor, the ExprNodeConstantDesc is created
> from strVal:
> {code}
> else if (expr.getText().endsWith("BD")) {
> // Literal decimal
> String strVal = expr.getText().substring(0, expr.getText().length()
> - 2);
> HiveDecimal hd = HiveDecimal.create(strVal);
> int prec = 1;
> int scale = 0;
> if (hd != null) {
> prec = hd.precision();
> scale = hd.scale();
> }
> DecimalTypeInfo typeInfo = TypeInfoFactory.getDecimalTypeInfo(prec,
> scale);
> return new ExprNodeConstantDesc(typeInfo, strVal);
> }
> {code}
> It should use HiveDecmal:
> return new ExprNodeConstantDesc(typeInfo, hd);
