 Combining fill_history option and where clause, stream can processing data of specific time range. For example, only process data after a past time. (In this case, 2020-01-30)
 
 ```sql
-create stream if not exists s1 fill_history 1 into st1  as select count(*) from t1 where ts > timestamp '2020-01-30' interval(10s)
+create stream if not exists s1 fill_history 1 into st1  as select count(*) from t1 where ts > '2020-01-30' interval(10s)
 ```
 
 As another example, only processing data starting from some past time, and ending at some future time.
 
 ```sql
-create stream if not exists s1 fill_history 1 into st1  as select count(*) from t1 where ts > timestamp '2020-01-30' and ts < timestamp '2023-01-01 '> interval(10s)
+create stream if not exists s1 fill_history 1 into st1  as select count(*) from t1 where ts > '2020-01-30' and ts < '2023-01-01' interval(10s)
 ```
 
 If some streams are totally outdated, and you do not want it to monitor or process anymore, those streams can be manually dropped and output data will be still kept.

 结合 fill_history 1 选项，可以实现只处理特定历史时间范围的数据，例如：只处理某历史时刻（2020年1月30日）之后的数据
 
 ```sql
-create stream if not exists s1 fill_history 1 into st1  as select count(*) from t1 where ts > timestamp '2020-01-30' interval(10s)
+create stream if not exists s1 fill_history 1 into st1  as select count(*) from t1 where ts > '2020-01-30' interval(10s)

 再如，仅处理某时间段内的数据，结束时间可以是未来时间
 
 ```sql
-create stream if not exists s1 fill_history 1 into st1  as select count(*) from t1 where ts > timestamp '2020-01-30' and ts < timestamp '2023-01-01 '> interval(10s)
