> Add a new SQL function try_cast. try_cast is identical to CAST with `spark.sql.ansi.enabled` as true, except it returns NULL instead of raising an error. This expression has one major difference from `cast` with `spark.sql.ansi.enabled` as true: when the source value can't be stored in the target integral(Byte/Short/Int/Long) type, `try_cast` returns null instead of returning the low order bytes of the source value.
