declare cur1 cursor for
       --xtype in (231,167,239,175,99,35) 为char,varchar,nchar,nvarchar,ntext,text类型

     --update tablename set fieldA=replace(cast(fieldA as varchar(8000)) ,'aa','bb')这样的语句。
     exec sp_executesql @sql     
     set @iRow=@@rowcount
     set @iResult=@iResult+@iRow
     if @iRow>0
     begin
print '表：'+@tableName+' ,列:'+@columnName+'被更新'+convert(varchar(10),@iRow)+'条记录;'
     end     
     fetch next from cur1 into @columnName

end
close cur1
deallocate cur1
fetch next from cur into @tableName,@tbID
end
print '数据库共有'+convert(varchar(10),@iResult)+'条记录被更新!!!'
close cur
deallocate cur
set nocount off 

上面就是批量删除数据库中所有字符串后面被挂JS木马的批量删除语句，记录下。
