   The statement I wrote is as follows:
   
   CREATE TABLE `F_PO_DETAIL` 
   (
       ...
       `SK_MONTH` INT NOT NULL COMMENT "订货年月代理键",
       `PRODUCT_NO` VARCHAR(30) NOT NULL COMMENT "产品代码键",
       `PO_TOT_AMT` DECIMAL(27, 5) NULL COMMENT "销售额",
       ...
   )
   ENGINE=OLAP
   DUPLICATE KEY(`DM_ETL_TIME`, `DM_DC_TIME`, `SK_MONTH`)
   PARTITION BY RANGE(`SK_MONTH`)()
   DISTRIBUTED BY HASH(`SK_MONTH`)
   PROPERTIES 
   (
       "dynamic_partition.time_unit" = "MONTH",
       "dynamic_partition.prefix" = "p",
       "dynamic_partition.buckets" = "10"
   );
   
   But it doesn’t meet my needs. 
   I saw the official document but the examples given are all for managing 
future data.
   How to import historical data with dynamic partition?
