我有一个像上面一样的表（cycle_set），并且想要获取（cycleNO，month，year，start date，close date）条件为state = 0和start-close date，其中包含下个月内的系统日期状态=0。

输出应该是：

cycleNO | month | year | start date | close date

SELECT cycleNO,month,year,start_date,close_date FROM cycle_set
WHERE state=0
AND MONTH(start_date) = (SELECT month FROM cycle_set WHERE state=0 AND...)
AND MONTH(close_date) = (SELECT month FROM cycle_set WHERE state=0 AND...)

问题是，您无法选择下一个结果月。这两个子选择中的 WHERE 子句中有什么内容？

如果您提取所有数据，然后在 PHP 或您正在使用的任何工具中处理它会容易得多。

select cycleNO,month,year,start_date,close_date 
FROM cycle_set
WHERE state=0 and sysdate between start_date and close_date

更新：如果你想同时获得当前和下个月：

select cycleNO, month, year, start_date, close_date 
FROM cycle_set
WHERE state=0 
   and ( sysdate between start_date and close_date or --current month
         sysdate between add_months(start_date,-1)  and close_date --next_month
        )

假设您有一个数据集（如示例所示）：

    SELECT  cycleno,month,year,start_date,close_date 
      FROM  cycle_set
     WHERE  state=0 
       AND  (   month = EXTRACT(month FROM sysdate) 
             OR month = EXTRACT(month FROM sysdate)+1
            )
  ORDER BY  cycleno, month, year, start_date
