如何根据雪花(SQL)中最小和最大之间的所有值的范围创建行?

Question

假设我有以下数据:

<表类> ID T_Min T_Max tbody><<tr>135214

样本数据:

CREATE OR REPLACE TABLE T1 (
ID INT,
T_Min INT,
T_Max INT);
INSERT INTO T1(ID, T_Min, T_Max)
SELECT * FROM VALUES (1, 3, 5), (2, 1, 4) t(ID, T_Min, T_Max);

解决方案:

WITH N AS (
SELECT ROW_NUMBER() OVER(ORDER BY SEQ4()) AS T FROM TABLE(GENERATOR(ROWCOUNT => 1000)) -- Set to the maximum value of the difference between T_Max and T_Min
)
SELECT T1.ID, N.T
FROM T1
JOIN N ON N.T BETWEEN T1.T_Min AND T1.T_Max
ORDER BY T1.ID, N.T;
