> create table t1 (c1 DECIMAL(38,6));
> create table t2 (c2 TIMESTAMP);
> insert into t1 select * from t2;

> select cast(cast('2012-12-19 11:12:19.1234567' as timestamp) as
> decimal(30,8)){code}
> But it'll throw exception "The cast conversion from TIMESTAMP type to NUMERIC
> type is not allowed" with Hive dialect in Flink.
