> The result is error when casting binary type as varchar type.
> For example,
> {code:java}
> @Test
> def testCast1(): Unit = {
>   testSqlApi(
>     "CAST(X'68656c6c6f' as varchar)",
>     "hello")
> }
> {code}
> The result is
> {code:java}
> Expected :hello
> Actual   :[B@57fae983
> {code}
> It is right as follow,
> {code:java}
> @Test
> def testCast(): Unit = {
>   testSqlApi(
>     "CAST(CAST(X'68656c6c6f' as varbinary) as varchar)",
>     "hello")
> }
> {code}
> We just need to change 
> {code:java}
> case (VARBINARY, VARCHAR | CHAR){code}
> to 
> {code:java}
> case (BINARY | VARBINARY, VARCHAR | CHAR) 
> {code}
> in ScalarOperatorGens#generateCast.
