> TableAPI {{testAllPassingFilter}}:
> {code}
> val t = util.addTable[(Int, Long, String)]('int, 'long, 'string)
> val resScala = t.filter(Literal(true)).select('int as 'myInt, 'string)
> val resJava = t.filter("TrUe").select("int as myInt, string")
> {code}
> We got error:
> {code}
> org.apache.flink.table.api.ValidationException: Cannot resolve [TrUe] given
> input [int, long, string].
> {code}
> The error is caused by :
> {code}
> lazy val boolLiteral: PackratParser[Expression] = ("true" | "false") ^^ {
> str => Literal(str.toBoolean)
> }
> {code}
> I want improve the method as follow:
> {code}
> lazy val boolLiteral: PackratParser[Expression] =
> ("(t|T)(r|R)(u|U)(e|E)".r | "(f|F)(a|A)(l|L)(s|S)(e|E)".r) ^^ { str =>
> Literal(str.toBoolean)}
> {code}
> Is there any drawback to this improvement? Welcome anyone feedback ?
