OrientDB REST API ignoreError

Question

这是我每天的 OrientDB 问题：

是否可以在通过 REST 执行一批命令期间忽略错误 API？

我正在使用

等命令在节点之间创建边

CREATE EDGE ManagedBy FROM (SELECT FROM Employee WHERE account = '<theId>') TO (SELECT FROM Employee WHERE account = '<theId>')

事实是有时指定的帐户不在数据库中，因此我得到以下错误：

Error:com.orientechnologies.orient.core.exception.OCommandExecutionException: No edge has been created because no source vertices

由于我对无法创建边这一事实感到满意，因此我想跳过返回的错误以便插入尽可能多的边。

目前我正在一条一条地插入边，我认为使用批量插入会大大加快这个过程。

最后我听从了@wolf4ood 的建议：我创建了一个 insert_edge JS 服务器函数，我为我想要创建的每个边调用它。如果目标节点和源节点存在，则创建边，否则不采取任何操作。这是它的正文：

var g = orient.getGraph();
var fromQ = "SELECT FROM " + fromTable + " WHERE " + fromField + " = '" + fromValue + "';";
var toQ = "SELECT FROM " + toTable + " WHERE " + toField + " = '" + toValue + "';";

var from = g.command('sql', fromQ, []);
var to = g.command('sql', toQ, []);

if(from.length > 0 && to.length > 0) {
    var createQ = "CREATE EDGE " + edgeType + " FROM (SELECT FROM " + fromTable + " WHERE " + fromField + " = '" + fromValue + "')" + " TO (SELECT FROM " + toTable + " WHERE " + toField + " = '" + toValue + "');";

    return g.command('sql', createQ, []);
}

return null;

参数为fromTable, fromField, fromValue, sourceTable, sourceField, sourceValue, edgeType。我这样调用函数：

SELECT insert_edge('Employee', 'account', <theId>, 'Employee', 'account', <theManager>, 'ManagedBy')
