Ramin Gharib updated FLINK-37926:
---------------------------------
Description:
h2. Casting
* A primitive value Variant can be cast to the corresponding type. An
exception will be thrown in case of a type error if `CAST` is used, and null
will be returned if `TRY_CAST` is used.
* An array variant can be cast to ARRAY<T> type, and each element will be cast
to type T. An exception will be thrown in case of a type error if `CAST` is
used, and null will be returned if `TRY_CAST` is used.
* An object variant can be cast to ROW or STRUCTURED type. An exception will
be thrown in case of a type error if `CAST` is used, and null will be returned
if `TRY_CAST` is used.
