> {noformat}
> CAST(<datetime> AS <char string type> [FORMAT <template>])
> CAST(<char string> AS <datetime type> [FORMAT <template>])
> {noformat}
> to specify patterns to use during cast.
> Oracle DB 18 already supports a similar formatting option during cast: [https://docs.oracle.com/en/database/oracle/oracle-database/18/sqlrf/CAST.html]
> There is an initiative in Impala: IMPALA-4018 and Hive HIVE-21575 to support.
