如何使用行號對這個BigQuery查詢進行分頁？

Question

如何更新此BigQuery查詢以允許其他分頁語句？

SELECT test.id, test.city, ROW_NUMBER() OVER () rownumber FROM prod.test LEFT OUTER JOIN prod.locations AS location ON (test.city = location.id)
WHERE active = true 
AND rownumber BETWEEN 10000 AND 30000 

產生的錯誤是：

無法識別的名稱：行號

Answer 1

對於此示例，使用子查詢：

SELECT t.*
FROM (SELECT test.id, test.city, ROW_NUMBER() OVER () rownumber
      FROM prod.test LEFT OUTER JOIN
           prod.locations location
           ON test.city = location.id
      WHERE active = true
     ) t 
WHERE rownumber BETWEEN 10000 AND 30000 ;

但是，您可能應該使用LIMIT和OFFSET 。

Answer 2

您也可以使用CTE

with cte as
(
 SELECT test.id, test.city, ROW_NUMBER() OVER () rownumber 
 FROM prod.test LEFT OUTER JOIN prod.locations AS location ON (test.city = location.id)
WHERE active = true
 ) select * from cte where rownumber BETWEEN 10000 AND 30000 

rownumber是直接在where子句中不支持的內聯別名

Answer 3

如果bigquery支持，則可以使用此標准sql子句，

SELECT 
       test.id
      ,test.city
FROM prod.test as test 
LEFT OUTER JOIN prod.locations AS location ON (test.city = location.id)
    WHERE active = true
order by test.id
offset 10000 rows fetch next 20000 rows only
