通过搜索匹配的字符串来删除此病毒

Question

我有这个病毒的截图：

如何查找以<div style="display:none">开头并以</div>结尾的字符串并将其删除？

Answer 1

岂不：

--To Check    
SELECT * 
FROM [YOUR_TABLE]
WHERE [YOUR_COLUMN] like '<div style="display:none">%'

--To delete
DELETE FROM [YOUR_TABLE]
WHERE [YOUR_COLUMN] like '<div style="display:none">%'

为你工作？

修改

听起来你需要在Where子句中使用正则表达式：

UPDATE
lg 
SET lg.ACIKLAMA = REPLACE(lg.ACIKLAMA,t.cleaned,'')
 FROM log_GENELPARAMETRELER lg JOIN ( 


SELECT lg2.PARAMKOD , SUBSTRING(lg2.ACIKLAMA,(CHARINDEX('<div style="display:none">',lg2.ACIKLAMA)),(LEN(lg2.ACIKLAMA) - CHARINDEX('<div style="display:none">',lg2.ACIKLAMA) + 1)) AS cleaned

  FROM log_GENELPARAMETRELER lg2 WHERE lg2.ACIKLAMA LIKE '%<div style="display:none">%' ) t ON lg.PARAMKOD = t.PARAMKOD
