Question

在我的数据库CU242176中，DBMS OrientDB版本2.0.7是一个表M_PERM：

PERM_DESC:string;
PERM_ID:integer not null;
PERM_NAME:string.

在我的数据库CU242176中，DBMS DB2版本9.1是具有相同结构的表M_PERM。在这个表14行。使用模块Orientdb-ETL，我确实导入了数据。没有错误，但表中没有数据。而表是在PERM_ID上创建索引。这是我的配置：

    {
  "config":{
    "log": "debug"
  },
  "extractor" : {
    "jdbc": 
    {  "driver": "com.ibm.db2.jcc.DB2Driver",
       "url": "jdbc:db2://ITS-C:50000/CU242176",
       "userName": "metr",
       "userPassword": "metr1",
       "query": "select PERM_DESC,PERM_ID,PERM_NAME from METR.M_PERM"
    }
  },
  "transformers":[
  ],
  "loader" : {
    "orientdb": {
      "dbURL": "plocal:c:/Program Files/orientdb-community-2.0.7/databases/CU242176",
      "dbUser": "admin",
      "dbPassword": "admin",
      "dbAutoCreate": false,
      "standardElementConstraints": false,
      "tx":true,
      "wal":false,
      "batchCommit":1000,
      "dbType": "document",
      "classes":[{"name": "M_PERM"}],
      "indexes": [{"class":"M_PERM", "fields":["PERM_ID:integer"], "type":"UNIQUE" }]
    }
  }
}

日志执行命令（oetl config_Import_M_PERM_JDBC.json）：

OrientDB etl v.2.0.7 (build @BUILD@) www.orientechnologies.com
[orientdb] DEBUG Opening database 'plocal:c:/Program Files/orientdb-community-2.0.7/databases/

END ETL PROCESSOR

如何解决此问题？对于加载到我的表格中的14行。

Answer 1

而不是：

"classes": [{"name": "M_PERM"}],

使用：

  "class": "M_PERM"

我无法在任何地方看到这一点，但它对我有用。

从RDBMS DB2导入到文档DB OrientDB
