>  * 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.
