如何避免使用子查询连接时发生InternalError

Question

运行查询时连接两个子查询时出现internalError。查询看起来是这样的：

SELECT data_table.title AS name 
FROM 
    ( 
    SELECT id, title 
    FROM 
    [citrius-altrius-fortius:analyze.topic_735_1354233600], [citrius-altrius-fortius:analyze.topic_735_1354320000] 
) AS data_table 
    INNER JOIN 
    ( 
    SELECT id FROM 
    [citrius-altrius-fortius:analyze.topic_735_1354233600], [citrius-altrius-fortius:analyze.topic_735_1354320000] 
    WHERE 
    UPPER(title) CONTAINS ("BUDGET") 
) AS filter_table 
ON data_table.id == filter_table.id 

这是我的答复得到：

} 

冠军和ID是纯字符串列（不重复）。这两个表的大小都相当小（在连接的右侧添加限制1000并不会改变任何内容）。但是，如果将查询更改为仅使用一个表格：

SELECT data_table.title AS name 
FROM 
    ( 
    SELECT id, title 
    FROM 
    [citrius-altrius-fortius:analyze.topic_735_1354233600] 
) AS data_table 
    INNER JOIN 
    ( 
    SELECT id FROM 
    [citrius-altrius-fortius:analyze.topic_735_1354233600] 
    WHERE 
    UPPER(title) CONTAINS ("BUDGET") LIMIT 1000 
) AS filter_table 
ON data_table.id == filter_table.id 

它每次都有效。 加入两个子查询（子查询）从多个表中进行选择的正确方法是什么？

你打一个已知的bug在加入做一个表格工会： BigQuery - UNION on left side of JOIN == Unexpected. Please try again

我们正在积极努力解决这个问题。
