推荐答案

我想您正在谈论这样的事情.

I suppose you are talking about something like this.

此消息是由Fuseki组件YASGUI(或更确切地说是YASQE)产生的警告.

This message is a warning produced by Fuseki component called YASGUI (or rather YASQE).

您有两个选择:

• 使用更多符合标准语法，i. e. SELECT DISTINCT ?id (str(?name) AS ?str_name)等

• Use more conformant syntax, i. e. SELECT DISTINCT ?id (str(?name) AS ?str_name) etc.

忽略此警告并运行查询，Jena ARQ应该接受它并返回结果.

Ignore this warning and run your query, Jena ARQ should accept it and return a result.
