Google bigquery Google Bigquery，BrowserTool-查询运行，但在定义目标表时不运行

我正在使用浏览器工具

当我只是“运行查询”时，查询会完美执行，但当我启用选项并定义目标表时，会出现错误：

错误：record.subject.Equity\u代码不是联接中任一表的字段 作业ID:robotic-weft-474:Job_6IDQeNNhONJRttK6P-44a9rNqkE

以下是查询：

record.subject.Tax_ID,
record.subject.Equity_Code,
comp_group.num_comps,

FROM
(

    (
    SELECT *
    FROM [flat_file.dallas_flatfile]
    WHERE 
        Assessed_Value>=1000000

    ) as subject
