Question

का उपयोग कर asp.net mvc3 ऐप में डेटाबेस (स्क्लाइट) खोलने में असमर्थ मैं एक एएसपीएनटी एमवीसी 3 वेब एप्लिकेशन लिख रहा हूं। मैं एक स्क्लाइट डेटाबेस का उपयोग करना चाहता हूँ। दुर्भाग्य से मुझे एक SQLiteException मिलता है जो "डेटाबेस खोलने में असमर्थ" कहता है।

वसंत-संस्करण: 1.3.2

NHibernate-संस्करण: 3,2

DbProvider/connectionstring:

<db:provider id="employeesDbProvider" 
      provider="SQLite-1.0.72" 
      connectionString="Data Source=.\Database\Employees.db3;Version=3;"> 
</db:provider> 

स्टैकट्रेस: ​​

bei NHibernate.Connection.DriverConnectionProvider.GetConnection() 

मैंने डेटासोर्स को एक पूर्ण पथ (सी: \ temp \ डेटाबेस \ Employees.db3) पर सेट करने का भी प्रयास किया है, लेकिन वही SqLiteException फेंक दिया गया है।

Answer 1

मैं SQLite, Spring.Net साथ एक त्वरित परीक्षण किया था और यह एक ही त्रुटि के साथ विफल, लेकिन जब मैं बैकस्लैश बजाय स्लैश इस्तेमाल किया कनेक्शन स्ट्रिंग में यह जादुई रूप से काम करना शुरू कर देता है।

<db:provider id="employeesDbProvider" 
    provider="SQLite-1.0.72" 
    connectionString="Data Source=c:/temp/Database/Sample.db3;Version=3;"> 
</db:provider> 

संपादित करें: मैं थोड़ा पता लगाने के लिए जहां फ़ाइल अगर मैं डॉट का उपयोग उपसर्ग जैसे संग्रहीत किया जाता है और आगे जांच की ./Employees.db3। IISExpress में इसे C:\Program Files (x86)\IIS Express में संग्रहीत किया जाता है, जो संभवतः आपने अपेक्षा की थी।

आईआईएस 7 में यह Unable to open the database file त्रुटि के साथ बस विफल रहता है, ihmo क्योंकि यह Temporary ASP.NET Files फ़ोल्डर को लिखने का प्रयास करता है।

सबसे सुरक्षित शर्त

<db:provider id="employeesDbProvider" 
    provider="SQLite-1.0.72" 
    connectionString="Data Source=|DataDirectory|Sample.db3;Version=3;"> 
</db:provider> 

उपयोग करने के लिए कौन सा अपने MVC आवेदन की App_Data फ़ोल्डर है।

मैंने अपने परीक्षणों के लिए SQLite 1.0.80.0 का उपयोग किया। ध्यान रखें कि SQLite निर्देशिका नहीं बनाता है और एसीएल लिखने के अधिकारों की आवश्यकता है।
