我正在尝试使用Python脚本(pyorient)在两个顶点之间创建边缘,但是我收到了一个奇怪的错误消息。我正在遵循OrientDB SQL语法,查询如下:
public class MyPatternLayout extends PatternLayout {
private List<String> test = new ArrayList<>();
public void addTest(String test) {
this.test.add(test);
}
@Override
public String doLayout(ILoggingEvent event) {
return test.stream().collect(Collectors.joining(", ")); //temporary, for testing purposes only
}
}
我得到的错误信息是:
client.command("Create ExtModToTimePoint from (select from ExtendedModel where name = 'EM') to (select from TimePoint where date = %s)" % today)
有没有人见过这个?
谢谢!

正确的命令是CREATE EDGE
