OrientDB.RequestError：无法找到该命令请求的命令执行：SQL＃11.1

我与OrientDB（社区版V1.7-RC2）/ Oriento试验（0.4.0）OrientDB.RequestError：无法找到该命令请求的命令执行：SQL＃11.1

功能

function linkChildToParent(oChild, oParent) { 
    return (
     oDB.edge.from(oChild).to(oParent) 
     .create({"@class": 'OrgUnit_isPartOf_OrgUnit'}) 
     .tap(log) 
     .return(oChild) 
    ); 
}

与异常

       throw res.e; 
         ^

所以我调试到驱动程序，直到我发现

失败

命令的内容return db.query(command);前右是

CREATE EDGE OrgUnit_isPartOf_OrgUnit FROM (#11.1) TO (#11.0)

然后我用的（基于浏览器）的控制台来验证OrgUnit_isPartOf_OrgUnit实际上是从边缘继承。我也验证过它会将OrgUnit与OrgUnit顶点链接起来，并且OrgUnit是从顶点引出的。我还仔细检查了记录＃11.1和＃11.0实际存在于数据库中。

然后我在控制台发出

CREATE EDGE OrgUnit_isPartOf_OrgUnit FROM (#11.1) TO (#11.0)

直接找来

com.orientechnologies.orient.core.command.OCommandExecutorNotFoundException: Cannot find a command executor for the command request: sql.#11:1

这基本上是相同的异常。有了Google，我发现了一些Javadoc for this exception。然而，这并没有帮助我。

什么是错，我该如何解决？

正确的命令应该没有括号。括号执行子查询：

CREATE EDGE OrgUnit_isPartOf_OrgUnit FROM #11:1 TO #11:0

有关更多信息，请参阅Create Edge命令。

有趣。现在我必须弄清楚为什么查询生成器会放入palenthesis。但这肯定是造成了这个问题。 – 2014-09-24 05:13:58
