SELECT DATA_TIME, DATA_VALUE FROM YXDDZH_MIDDLE.GZ_SCREEN_SY_REGULATORY_LAW WHERE IS_DELETED = 0 AND DATA_NAME = '日期' AND DATA_TIME <= CURDATE() ORDER BY DATA_TIME DESC LIMIT 12;这个SQL怎么修改

根据你的描述，如果想要查询的表中，日期列名为`DATA_TIME`，日期值列名为`DATA_VALUE`，表名为`YXDDZH_MIDDLE.GZ_SCREEN_SY_REGULATORY_LAW`，并且查询的条件为`IS_DELETED = 0`，`DATA_NAME = '日期'`，则可以按照以下方式修改SQL语句，查询距离当前日期最近的12条数据：

SELECT DATA_TIME, DATA_VALUE
FROM YXDDZH_MIDDLE.GZ_SCREEN_SY_REGULATORY_LAW
WHERE IS_DELETED = 0
  AND DATA_NAME = '日期'
  AND DATA_TIME <= CURDATE()
ORDER BY DATA_TIME DESC
LIMIT 12;

这个查询会选取日期列小于或等于当前日期的所有数据，按照日期列倒序排列，最后限制结果集只包含前12条数据，并且只包含`DATA_TIME`和`DATA_VALUE`这两列。

SELECT DATA_TIME,DATA_VALUE FROM YXDDZH_MIDDLE.GZ_SCREEN_SY_REGULATORY_LAW WHERE IS_DELETED = 0 AND DATA_NAME = '日期' ORDER BY DATA_TIME limit -12;

这是一个SQL语句，根据条件查询YXDDZH_MIDDLE数据库中GZ_SCREEN_SY_REGULATORY_LAW表中的DATA_NAME为'日期'，且IS_DELETED为0的数据，并按DATA_TIME从小到大排序，返回最后12条数据的DATA_TIME和DATA_VALUE字段。其中limit -12表示返回倒数12条数据。

CONFIG_CFG80211_REG_DEBUG

CONFIG_CFG80211_REG_DEBUG is a configuration option in the Linux kernel that enables debug messages related to regulatory domain handling in the cfg80211 subsystem. When enabled, it prints debugging information about regulatory domain updates, channel switching, and other regulatory-related events. This can be useful for developers and system administrators who need to troubleshoot issues related to wireless networking and regulatory compliance. However, it may also generate a large amount of log data, which can impact system performance and consume storage space. Therefore, it is recommended to enable this option only when necessary and disable it in production environments.
