如何在BigQuery Standard SQL中生成系列

Question

我需要生成表说,连续600号的每一行中(从51)
我如何做到这一点与BigQuery标准SQL？

Answer 1

尝试GENERATE_ARRAY标准SQL:

SELECT num FROM UNNEST(GENERATE_ARRAY(51, 650)) AS num;

Answer 2

BigQuery 标准 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

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，例如获得连续的天数和其他序列
