如何联合两个以临时 table 逻辑 BigQuery SQL 开头的 table

Question

我有两个表需要合并。两者逻辑相同，只是源表不同。查询如下所示：

with origin_table as (
    SELECT
        date,
        (
            SELECT
                value
            FROM
                UNNEST(hits.customDimensions)
            WHERE
                INDEX = 10
        ) AS second_scroll,
        (
            SELECT
                value
            FROM
                UNNEST(hits.customDimensions)
            WHERE
                INDEX = 11
        ) AS dwell
    FROM
        (
            SELECT
                date,
                hits,
            FROM
                `table_1`,
                UNNEST(hits) AS hits
        )
    GROUP BY
        1
    select
        date,
        case
            when second_scroll is not null
            AND dwell is not null then 1
            when second_scroll is null
            AND dwell is not null then 0
            when second_scroll is not null
            AND dwell is null then 0
        end as ENGAGEMENT
    from
        origin_table

这个查询工作得很好，但是当我在下面添加完全相同的查询时，它从 table_2 中提取数据并使用 UNION ALL 我有以下错误：Syntax error: Expected "(" or keyword SELECT but got keyword WITH 所以查询不能以 with table as 开头。现在用这个逻辑联合两个表？

我认为这很接近...需要更多关于问题性质的详细信息或重新创建它以隔离问题的能力...
