Java -执行AQL查询失败

Question

如何修正AQL语法错误？我试图使用查询创建边缘，但出现以下错误：

执行查询失败。响应: 400，错误: 1501 - AQL:语法错误，查询字符串在1:57位置附近意外结束(解析时)

用于执行查询的代码：

try {

 String query = "INSERT { _from:TurmaA._teste2, _to:TurmaA._testepedro } IN @edges";
 Map<String, Object> bindVars = new MapBuilder().put("edges", nome2).get();
 ArangoCursor<BaseDocument> cursor = arangoDB.db(dbName).query(query, bindVars, 
null, BaseDocument.class);

cursor.forEachRemaining(aDocument -> {
  System.out.println("Key: " + aDocument.getKey());
 });
} catch (ArangoDBException e) {
 System.err.println("Failed to execute query. " + e.getMessage());
}

请注意，@@。

因此，您的代码示例可能很容易修复如下：

try {

 String query = "INSERT { _from:TurmaA._teste2, _to:TurmaA._testepedro } IN @@edges";
 Map<String, Object> bindVars = new MapBuilder().put("@edges", nome2).get();
 ArangoCursor<BaseDocument> cursor = arangoDB.db(dbName).query(query, bindVars, 
null, BaseDocument.class);

cursor.forEachRemaining(aDocument -> {
  System.out.println("Key: " + aDocument.getKey());
 });
} catch (ArangoDBException e) {
 System.err.println("Failed to execute query. " + e.getMessage());
}
