问题

我正在尝试在ArangoDB的单个查询中执行多次插入。具体来说,它们如下:

response.Message.Value.TryGetValue("Version", out object result); 

具有以下参数:

INSERT { _key: @personId, firstName: @firstName, lastName: @lastName, gender: @gender, birthday: @birthday, birthday_day: @birthday_day, birthday_month: @birthday_month, creationDate: @creationDate, locationIP: @locationIP, browserUsed: @browserUsed, email:
@email, speaks: @speaks } INTO Person
 INSERT { _from: Person/@personId, _to: Place/@placeId } INTO isLocatedIn
 INSERT { _from: Person/@personId, _to: Tag/@tag0Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag1Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag2Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag3Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag4Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag5Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag6Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag7Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag8Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag9Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag10Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag11Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag12Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag13Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag14Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag15Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag16Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag17Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag18Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag19Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag20Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Tag/@tag21Id } INTO hasInterest
 INSERT { _from: Person/@personId, _to: Organisation/@studyOrg0Id, classYear: @classYear0 } INTO studyAt
 INSERT { _from: Person/@personId, _to: Organisation/@workOrg0Id, classYear: @workFrom0 } INTO workAt
 INSERT { _from: Person/@personId, _to: Organisation/@workOrg1Id, classYear: @workFrom1 } INTO workAt

但是当我尝试执行此操作时,出现以下错误:

Params: {personId=35184372096260, firstName=André, lastName=Atem, gender=female, birthday=501897600000, birthday_day=27, birthday_month=11, creationDate=1347546700674, locationIP=41.205.16.11, browserUsed=Internet Explorer, email=[Andre35184372096260@yahoo.com], speaks=
[en], placeId=1048, tag0Id=285, tag1Id=441, tag2Id=1761, tag3Id=2019, tag4Id=2800, tag5Id=2832, tag6Id=4994, tag7Id=5116, tag8Id=5446, tag9Id=5531, tag10Id=5677, tag11Id=6369, tag12Id=7340, tag13Id=7756, tag14Id=7853, tag15Id=8219, tag16Id=8481, tag17Id=9738, tag18Id=98
68, tag19Id=10410, tag20Id=11121, tag21Id=11211, studyOrg0Id=1980, classYear0=2004, workOrg0Id=205, workFrom0=2006, workOrg1Id=209, workFrom1=2005}

似乎在ArangoDB中,我无法在一个查询中向同一集合中插入两次?我是否需要针对每个插入内容执行单独的查询?

感谢您的帮助!

解决方案

使用Exception in thread "main" com.arangodb.ArangoDBException: Response: 400, Error: 1579 - AQL: access after data-modification by collection 'Person' (while optimizing ast) at com.arangodb.internal.util.ResponseUtils.checkError(ResponseUtils.java:53) at com.arangodb.internal.velocystream.VstCommunication.checkError(VstCommunication.java:146) at com.arangodb.internal.velocystream.VstCommunicationSync.execute(VstCommunicationSync.java:128) at com.arangodb.internal.velocystream.VstCommunicationSync.execute(VstCommunicationSync.java:42) at com.arangodb.internal.velocystream.VstCommunication.execute(VstCommunication.java:129) at com.arangodb.internal.velocystream.VstProtocol.execute(VstProtocol.java:47) at com.arangodb.internal.ArangoExecutorSync.execute(ArangoExecutorSync.java:71) at com.arangodb.internal.ArangoExecutorSync.execute(ArangoExecutorSync.java:53) at com.arangodb.internal.ArangoDatabaseImpl.query(ArangoDatabaseImpl.java:197) 构造重新定义AQL查询可以解决以下问题:

答案 0 :(得分:1)

通过Java驱动程序,您可以使用collection.insertDocuments 命令并传递要插入的文档数组。参见文档here

在http界面中,您可以使用

POST /_api/document/{collection}

并按照here的说明传递带有文档数组的json(请参阅创建文档部分)

最后,通常直接在AQL中使用FOR doc in [arrayOfDocs] insert {<stuff>} into collection

以下是在Web GUI中直接运行的AQL中插入多个记录的示例:

let Params =[ {personId:35184372096260, firstName:'André', lastName:'Atem'}, {personId:35184372096261, firstName:'Robert', lastName:'Smith'} ]

for item in Params
insert item into test5
