>Reporter: jiaan.geng
>Priority: Major

> In Spark, decode(bin, charset) - Decodes the first argument using the second
> argument character set.
> Unfortunately this is NOT what any other SQL vendor understands DECODE to do.
> DECODE generally is a short hand for a simple case expression:

> SELECT DECODE(c1, 1, 'Hello', 2, 'World', '!') FROM (VALUES (1), (2), (3)) AS
> T(c1)
> =>
> (Hello),
> (World)
> (!)
> {code}
