TRYCAST takes a string and tries to cast it to a data type specified after the AS keyword (similar to CAST). If the conversion fails, TRYCAST returns a NULL instead of failing.

The result of the conversion is returned unless there is an error, in which case a NULL is returned. The result data type is whatever data type was specified by the data_type input.
