+ description: Returns a new value being cast to type type. A CAST error
throws an exception and fails the job. If you're performing a cast operation
that may fail, like INT to STRING, you should rather use TRY_CAST, in order to
handle errors. E.g., CAST('42' AS INT) returns 42; CAST(NULL AS VARCHAR)
returns NULL of type VARCHAR; TRY_CAST('non-number' AS INT) throws an exception
and fails the job.
