Question

我试图运行简单的脚本，但不知何故它不起作用。不确定这是否包含最新快照或其他内容。

这是脚本。

script SQL
CREATE CLASS Person extends V;
CREATE VERTEX Person set name="Luca";
LET $a = (MATCH {class:Person, as:s} RETURN s);
select expand($a.s);
end

这是输出，我不明白它为什么会失败。另一件事是错误是三次而不是一次，所以这里缺少一些东西。我正在使用orientdb 3.0的最新快照

orientdb {db=demo}> script SQL
[Started multi-line command. Type just 'end' to finish and execute]

Error: java.lang.StringIndexOutOfBoundsException: String index out of range: -1
CREATE CLASS Person extends V;

OrientDB无法在orientdb中执行SQL脚本
