मेरे पास एक टेबल है PersonalInfo जैसे कॉलम जैसे आईडी, नाम, पता । मान लें कि मेरा डेटा निम्न है 1 जॉन यूएस 2 मार्क यूके 3 जॉन यूके 4 डेविड यूएस अब जब मैं नया रिकार्ड निम्न सम्मिलित करता हूं 5 जॉन चीन मैं पिछले रिकार्ड को उसी नाम के रूप में अद्यतन करना चाहता हूँ जैसा कि उदाहरण के लिए नया है जैसा कि यहां दिखाया गया है 3 जॉन यूके को 3 जॉन चीन पर अपडेट कर दिया जाएगा। जब मैं 5 वीं रिकॉर्ड को सम्मिलित करता है तो तालिका 1 जॉन यूएस 2 मार्क यूके 3 जॉन चीन 4 डेविड यूएस 5 जॉन चीन मुझे किस SQL ​​क्वेरी का उपयोग करना चाहिए? आईडी मान लेना ऑटो-वर्धित है, यह उस नाम और पता संयोजन के लिए सबसे अधिक मूल्य होगा। सेट पता personalinfo अद्यतन = 'अमेरिका' कहां आईडी = (चयन मैक्स (आईडी) personalinfo से जहां नाम = 'जॉन' और पता = 'ब्रिटेन')

I create an IPA with which it Successfully creates my application and creates an IPA, but when I want to upload it to testflightapp, I get this error: Invalid IPA: missing embedded provisioning profiles Are you sure that this Is an ad hoc? I have added the provisioning profile to create a profile like If I create an IPA manually with Xcode> Product> Archive, then I can successfully upload an IPA to testflightapp. So my guess is that Xcode Maven plugin can not read my provisional profile.

I am using IPA from this path: / target / checkout / src / xcode / build / debug-iphonimulator / target / checkout / src / xcode / build / release-iphoneos This was a stupid mistake.
