如何在 BigQuery Standard SQL 中生成系列 [英] How to generate series in BigQuery Standard SQL

问题描述

我需要用说每行600个连续数字(从51开始)生成表格
我如何使用 BigQuery 标准 SQL 做到这一点?

I need to generate table with say 600 consecutive numbers (starting with 51) in each row
How I do this with BigQuery Standard SQL?

推荐答案

BigQuery Standard SQL

BigQuery Standard SQL

SELECT 50 + ROW_NUMBER() OVER() AS num
FROM UNNEST((SELECT SPLIT(FORMAT("%600s", ""),'') AS h FROM (SELECT NULL))) AS pos
ORDER BY num

BigQuery 旧版 SQL

BigQuery Legacy SQL

SELECT 50 + pos AS pos FROM (
  SELECT ROW_NUMBER() OVER() AS pos, * 
  FROM (FLATTEN((SELECT SPLIT(RPAD('', 600, '.'),'') AS h FROM (SELECT NULL)), h))
) WHERE pos BETWEEN 1 AND 600

从那里你可以调整逻辑例如以获得连续的天数和其他序列

From there you can adjust logic for example to get consecutive days and other sequences
