Bigquery - 两列内多个值的总和乘积

Question

我有这个值

我想计算一个新列，它将添加 ticket_units_count 和价格的乘积，因此它必须是： 5 * 33104.0 + 4 * 23449.0 = 259316

如何在 bigquery 中做到这一点？我试过这个

SELECT 
SUM(CAST(price AS FLOAT64) * CAST(ticket_units_count AS INT64))
FROM table

但它显示此错误：错误的双精度值：33104.0；23449.0 需要您的帮助来指定查询以获得预期的结果

Answer 1

考虑以下方法

select *, 
  ( select sum(cast(_count as int64) * cast(_price as float64))
    from unnest(split(ticket_units_count, ';')) _count with offset
    join unnest(split(price, ';')) _price with offset
    using (offset)
  ) as total
from your_table

如果应用于您问题中的示例数据 - 输出为
