查询捕获时间戳注册00:00:00

Question

如何获取不使用默认DatePercentUpdate = 0000-00-00 00:00:00的时间戳的查询？我以为我使用0拥有了它，但是它捕获了注册00:00:00。

$stmtSummary = $mysqliSummary
    ->prepare("SELECT n.nodeID, n.percentRedYellow, n.count, c.Loopback_ip, c.city 
               FROM CATV.CableData  c 
               INNER JOIN CATV.node n ON n.nodeID = c.Node_ID   
               INNER JOIN CATV.CM cm ON cm.LoopbackIP=c.Loopback_ip
               WHERE c.LocationID IS NOT NULL 
                 AND c.Status_Update_Time <= NOW() 
                 AND c.Status_Update_Time >=(NOW() - INTERVAL 2 DAY) 
                 AND c.Status_Update_Time>0
                 AND n.DatePercentUpdate <= NOW() 
                 AND n.DatePercentUpdate >=(NOW() - INTERVAL 2 DAY) 
                 AND n.DatePercentUpdate>0
                 AND length(c.Node_ID)>0
               Group BY c.city, n.nodeID");

已添加：我尝试在线搜索以在查询中使用0000-00-00 00:00:00，但没有在过滤器中找到任何内容。

Answer 1

您可以像这样简单地使用>（大于）比较运算符或!=（不等于）比较运算符

WHERE `date_field` != '0000-00-00 00:00:00'

该示例将获取日期不等于该值的所有行。

Answer 2

捕获查询，其中时间戳为0000-00-00 00:00:00

选择行 select * from table_name where your_column = 0;

更新行 UPDATE table_name SET column_name = new_value where your_column = 0;

这将解决

mysql incorrect datetime value: '0000-00-00 00:00:00' mysql错误

Answer 3

SELECT DATE_FORMAT(field_date, "0000-00-00 00:00:00");
