来自平面文件的内部联接行集和 SQL

Question

我有如下所示的 TSV 文件。

Domain_ID   Domain_URL  Company_Name_1  Company_Type
179238792   sample.com  sample  IT

我有一个如下所示的 USQL table。

Domain_ID   Domain_URL  Company_Name_1
179238792   sample.com  sample

我正在尝试加入行集并尝试为每个公司获取 Company_Type。

脚本：

@result = EXTRACT
    Domain_ID int,
    Domain_URL string,
    Company_Name_1 string,
    Company_Type string
    FROM @"sample.txt"
    USING Extractors.Tsv(skipFirstNRows:1);
@result1=SELECT * FROM table
@result2= @result2= SELECT @result1.Company_Name_1 , @result1.Company_Type FROM @result1
        INNER  JOIN @result ON @result.Domain_ID==@result1.Domain_ID
OUTPUT @result2
            TO "/Mobius_POC/Output/Company_Type.tsv"
            USING Outputters.Tsv();

执行上述脚本时出现以下错误。
