我已经创建了这个配置文件：

{ 
    "config": { "log": "debug" }, 
    "extractor": { 
        "jdbc": {
            "driver":"com.ibm.db2.jcc.DB2Driver",

            "userName": "lidt9bl", 
            "userPassword": "Wam52017", 
            "query": "select * from DB2TST5.COMVTC" } }, 
    "transformers": [ 
{log: {prefix: "MySQL -> "}},
{"field": {"fieldName":"text", "value": "Medical Vendor Type Code"} }, 
{"field": {"fieldName":"code","expression": "COMVTC_C"} }, 
{"field": {"fieldName":"COMVTC_C", "operation" :"remove"} }, 
{"field": {"fieldName":"display", "expression" : "COMVTC_NM"} }, 
{"field": {"fieldName":"COMVTC_NM", "operation" : "remove"} },

{"field": {"fieldName":"userID", "expression" : "COMVTC_REC_MTN_ID"} },

{"field": {"fieldName":"system", "value": "1"} }, 
{"field": {"fieldName":"version", "value": "1"} }, 
{"field": {"fieldName":"userSelected", "value": false} }, 
{"vertex":{"class": "codeableConcept"} } ],
"loader": {
        "orientdb": {
            "dbURL": "plocal:localhost/p01/app/gdb/orientdb-community-2.2.17/databases/CorporateProviderData",
            "dbUser": "admin",
            "dbPassword": "admin",
            "dbAutoDropIfExists": false,
            "dbAutoCreate": false,
            "tx": false,
            "wal": true,
            "batchCommit": 2,
            "dbType": "graph",
            "dbAutoCreateProperties": true,
            "classes":[{"name":"codeableConcept", "extends": "coding"},{"name":"coding", "extends": "V"}]
             } } }

类 codeableConcept 已经存在但没有记录。选择表读取一个有两行的小表：

COMVTC_C COMVTC_STUS_C COMVTC_EFF_DT    COMVTC_TRM_DT   COMVTC_NM                 COMVTC_REC_MTN_TS             COMVTC_REC_MTN_ID
--------        -------------             -------------                   -------------            --------------------------------------------------   --------------------------  -----------------

我正在更改列名以匹配以下内容：

create class coding extends V;
create property coding.system string;
create property coding.version string;
create property coding.code string;
create property coding.display string;
create property coding.userSelected Boolean;
ALTER PROPERTY coding.system MANDATORY true;
ALTER PROPERTY coding.version MANDATORY true;
ALTER PROPERTY coding.code MANDATORY true;
CREATE INDEX Index_CodeSet_key ON coding (system,version,code) UNIQUE;

create class codeableConcept extends coding;
create property codeableConcept.text string;

这是日志的结尾：

[3:field] DEBUG Transformer output: {COMVTC_C:null,COMVTC_STUS_C:null,COMVTC_EFF_DT:null,COMVTC_TRM_DT:null,COMVTC_NM:null,COMVTC_REC_MTN_TS:null,COMVTC_REC_MTN_ID:null,text:Medical Vendor Type Code,code:MS,display:Medical Service                                   ,status:A,effectiveDate:1937-01-01,terminationDate:null,createTS:2007-01-15 02:06:29.416709,userID:APOLIDB ,system:1,version:1,userSelected:false}

它说它创建了 codeableConcept RID #22:8，但它不存在。

orientdb {db=CorporateProviderData}> info class codeableConcept

CLASS 'codeableConcept'

Records..............: 0

Default cluster......: codeableconcept (id=25)
Supported clusters...: codeableconcept(25), codeableconcept_1(26), codeableconcept_2(27), codeableconcept_3(28)

有任何想法吗？

我找到了解决方案。又看了几眼，不过是在dbURL里面。

"dbURL": "plocal:localhost/p01/app/gdb/orientdb-community-2.2.17/databases/CorporateProviderData"

由于使用了“localhost”，我没有意识到它正在另一个目录中创建一个新数据库。一旦我删除它，它就起作用了。
