multithreading - QMutex stuck in locked state -

-

I have a function that is part of a square and in this function there is a mute x at the beginning of the function. And a mute x just before its return. Unlock Now I had to face a situation where the mutex has been trapped in the looted state. What can this do if this function is the only place where I use to lock and unlock that Mute X The function is called from the main thread and 1 or 2 other qtthread.

Update: There was a problem due to not sleeping thread between function calls. Could the lack of sleep really add to Mutex fast? If you have been thrown into a function, then unlock

() Can not be executed at the end to ensure that in such cases QMutex unlocks, you can lock with the object. This object will automatically unlock the mute when it will be lost, even if it occurs during stack online after an exception.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
