mysql 列出所有日期

-- 创建一个示例表
CREATE TABLE example_table (
    id INT AUTO_INCREMENT PRIMARY KEY,
    date_column DATE
);

-- 插入日期序列
INSERT INTO example_table (date_column)
SELECT DATE_ADD('2023-01-01', INTERVAL n DAY)
FROM (
    SELECT a.N + b.N * 10 + c.N * 100 AS n
    FROM (SELECT 0 AS N UNION ALL SELECT 1 UNION ALL SELECT 2 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) a
    CROSS JOIN (SELECT 0 AS N UNION ALL SELECT 1 UNION ALL SELECT 2 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) b
    CROSS JOIN (SELECT 0 AS N UNION ALL SELECT 1 UNION ALL SELECT 2 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) c
) numbers
WHERE DATE_ADD('2023-01-01', INTERVAL n DAY) <= '2023-12-31';
