SInce `eval()` need input, you mean write it like this ?
```
protected def visitConstant(ctx: ConstantContext): String =
withOrigin(ctx) {
expression(ctx) match {
case l: Literal => if (l.value == null) {
null
} else {
Cast(l, StringType, Some(SQLConf.get.sessionLocalTimeZone))
.eval(InternalRow.apply(l.value)).toString
}
case _ =>
throw IllegalArgumentException("")
}
}
```
