MySQL Get Value On hour At specific date -


मेरी तालिका इस प्रकार दिखती है: 

  (int) युग, (स्ट्रिंग) मूल्य 12345 , 123.22 12346, 111.33 12347, 119.44 13211, 100.44 13255, 120.05 ...

मुझे दिए गए समय और तारीख में कीमत मूल्य प्राप्त करने में सक्षम होना चाहिए। उदाहरण: GetPriceAt ("12/01/2015 16:00")

यदि वास्तव में 12/01/2015 को 16:00 मान है, तो इसे वापस लौटाएं, अगर वहां पिछले मूल्य में वापस नहीं किया गया है टेबल। उदाहरण: 

  12/01/2015 13:00, 123.22 12/01/2015 13:01, 111.33 12/01/2015 13:50, 119.44 12/01/2015 14:10 , 100.44 12/01/2015 14:15, 120.05

GetPriceAt ("12/01/2015 14:00") - वापस 119.44 (13:50 से कीमत)

<पी> GetPriceAt ("12/01/2015 13:00") - 123.22 वापस आएगा (हमें यह एक था)

मैं MySQL कैसे पूछूं? बहुत बहुत धन्यवाद

(परीक्षण नहीं किया गया और नहीं)

I have been trying to use Qt5 multimedia to record audio with QAudioInput, however, when I see If QAudioInput is started, it increases the master volume of my sound device to 100%. How can I prevent QAudioInput from changing the master volume? My current development platform is Linux with PalsAdio (with flat audio disabled). How can I use QAudioInput : QAudioDeviceInfo device_info = QAudioDeviceInfo :: defaultInputDevice (); QAudio format format; Format.setSampleRate (44100); Format.setChannelCount (1); Format.setSampleSize (16); Format.setCodec ("Audio / PCM"); Format.setSampleType (QAudioFormat :: SignedInt); Format.setByteOrder (QAudioFormat :: LittleEndian); Std :: cout & lt; & Lt; Device_info.deviceName ().
