Question

我正在执行一个查询，该查询应该删除包含特定字符串的行：

DELETE FROM Event 
WHERE EventMessage LIKE '%Missing format string - selector:%' 
IN
Select WhenOccurred,EventMessage
From Event
Where WhenOccurred > DateFunc('now', -1)

我查看了有关删除和点赞语句的所有文档，但是我不知道为什么会出现此错误：

查询失败：“ DELETE”附近：语法错误

Answer 1

MySQL：

DELETE FROM Event 
WHERE EventMessage LIKE '%Missing format string - selector:%' ;

Select WhenOccurred,EventMessage
From Event
Where WhenOccurred >  NOW() - INTERVAL 1 DAY

Answer 2

您的问题似乎不完整

如果您只想删除具有事件消息（例如'％Missing格式字符串-选择器：％'）的记录，则仅运行第一个查询

DELETE FROM Event 
WHERE EventMessage LIKE '%Missing format string - selector:%'

或者如果您想添加更多条件，例如最近24小时内发生的删除事件

DELETE FROM Event 
WHERE EventMessage LIKE '%Missing format string - selector:%' and WhenOccurred >= DATEADD(hh, -24, GETDATE())

删除查询失败：“ DELETE”附近：语法错误
