尝试在时间戳之间检索值时出现错误代码：1064

Question

在我的表中，我有条目（与datetime数据类型），如：

我需要特定UNIX时间戳之间的结果。当我运行查询时：

Select ifnull(ji.JobID,'') as JobID, ifnull(ji.ReelIndex,'') as ReelIndex, ifnull(ji.FileName,'') as FileName, 
 ifnull(ji.MediaType,'') as MediaType, ifnull(ji.QCStatus,'') as QCStatus, ifnull(ji.QCComments,'') as QCComments, 
 ifnull(ji.PackagingStatus,'') as PackagingStatus, ci.Name 
from job_info as ji 
left join content_info as ci on 
 ji.ContainerID = ci.ID 
where ji.Progress = 100 
where ji.ProcessStartTime >= 1449081000 
  and ji.ProcessEndTime <= 1450549800 
order by Name asc, ReelIndex asc 
LIMIT 0 , 20

它会抛出错误：

  

错误代码：1064您的SQL语法出错;查看与您的MySQL服务器版本对应的手册   要使用的语法＆＃39;其中ji.ProcessStartTime＆gt; = 1449081000和   ji.ProcessEndTime＆lt; = 1450549800或＆＃39;在第4行

这可能是什么原因？

Answer 1

您需要使用WHERE加倍AND/OR：

SELECT ifnull(ji.JobID,'') AS JobID,
       ifnull(ji.ReelIndex,'') AS ReelIndex,
       ifnull(ji.FileName,'') AS FileName,
       ifnull(ji.MediaType,'') AS MediaType,
       ifnull(ji.QCStatus,'') AS QCStatus,
       ifnull(ji.QCComments,'') AS QCComments,
       ifnull(ji.PackagingStatus,'') AS PackagingStatus,
       ci.Name
FROM job_info AS ji
LEFT JOIN content_info AS ci 
  ON ji.ContainerID = ci.ID
WHERE ji.Progress = 100 
  AND ji.ProcessStartTime >= FROM_UNIXTIME(1449081000)     -- here 
  AND ji.ProcessEndTime <= FROM_UNIXTIME(1450549800)
ORDER BY Name ASC, ReelIndex ASC 
LIMIT 0, 20;

修改

如果您想跳过时间部分并将其设置为00:00:00 CAST至DATE：

...
AND CAST(ji.ProcessStartTime AS DATE) >= FROM_UNIXTIME(1449081000)     
AND CAST(ji.ProcessEndTime AS DATE) <= FROM_UNIXTIME(1450549800)

另请注意，您需要使用FROM_UNIXTIME将unix_timestamp转换为datetime。
