OrientDB.RequestError：無法找到該命令請求的命令執行：SQL＃11.1

我與OrientDB（社區版V1.7-RC2）/ Oriento試驗（0.4.0）OrientDB.RequestError：無法找到該命令請求的命令執行：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) 
    ); 
}

與異常

C:\Users\Udo\workspace\NodeOrient\node_modules\oriento\node_modules\bluebird\js\main\async.js:93 
       throw res.e; 
         ^

所以我調試到驅動程序，直到我發現

失敗

命令的內容return db.query(command);前右是

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

然後我用的（基於瀏覽器）的控制檯來驗證OrgUnit_isPartOf_OrgUnit實際上是從邊緣繼承。我也驗證過它會將OrgUnit與OrgUnit頂點鏈接起來，並且OrgUnit是從頂點引出的。我還仔細檢查了記錄＃11.1和＃11.0實際存在於數據庫中。

然後我在控制檯發出

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

直接找來

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

這基本上是相同的異常。有了Google，我發現了一些Javadoc for this exception。然而，這並沒有幫助我。

什麼是錯，我該如何解決？

正確的命令應該沒有括號。括號執行子查詢：

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

有關更多信息，請參閱Create Edge命令。

有趣。現在我必須弄清楚爲什麼查詢生成器會放入palenthesis。但這肯定是造成了這個問題。 – 2014-09-24 05:13:58
