OrientDB ETL导入日期字段

Question

我导入了一个包含人口统计信息的大表，我的ETL JSON看起来像这样

{
 "config": {
"log": "debug"
},
 "extractor" : {
  "jdbc": { "driver": "com.mysql.jdbc.Driver",
            "url": "jdbc:mysql://localhost/avicenna",
          "userName": "xxxxxx",
          "userPassword": "xxxxxxxxxxxx",
          "query": "select * from patients",
          "fetchSize": 1000 
          }
 },
 "transformers" : [
  { "vertex": { "class": "patients"} }
 ],
 "loader" : {
   "orientdb": {
  "dbURL": "plocal:c:/tools/orientdb-community-2.0.5/databases/Avicenna",
  "dbType": "graph",
  "dbAutoCreate": true
  }
 }
 }

我在OrientDB中的患者类定义如下

-------------------------------+-------------+
 NAME                          | TYPE        |
-------------------------------+-------------+
 PatientID                     | INTEGER     |
 MaritalStatus                 | STRING      |
 DOB                           | DATE        |
 Sex                           | STRING      |
-------------------------------+-------------+

尽管MySQL患者表将DOB字段创建为“日期”，但所有导入的数据仍会显示完整的DateTime

orientdb {db=avicenna}> select from patients limit 3

  ----+-----+--------+---------+-------------------+-------------+----+------------
#   |@RID |@CLASS  |PatientID|DOB                |MaritalStatus|Sex  |out_admitted
     ----+-----+--------+---------+-------------------+-------------+----+------------
0   |#18:0|patients|1022     |1996-02-29 00:00:00|Single       |M   |[size=5]
1   |#18:1|patients|1033     |1996-02-02 00:00:00|Single       |M   |[size=1]
2   |#18:2|patients|1089     |1995-07-21 00:00:00|Single       |F   |[size=1]
----+-----+--------+---------+-------------------+-------------+----+------------

我的导入脚本有问题吗？ 现在我如何清理OrientDB中的日期？

Answer 1

我相信你的剧本没有任何问题，这就是日期的存储方式。

create property V.someDate date
create property V.someDateTime datetime

insert into V set someDate = sysdate(), someDateTime = sysdate()

select from V
