सार्वजनिक वर्ग DBHelper SQLiteOpenHelper {सार्वजनिक DBHelper (संदर्भ संदर्भ) विस्तारित करता है {html>

मेरा DBHelper वर्ग 

  सुपर (संदर्भ, "SIMPLE_DB", अशक्त, 1); } @ ओवरराइड पब्लिक व्हाइड ऑन क्रिएट (SQLiteDatabase db) {db.execSQL ("टैबलेट सिंपल (" + "आईडी प्राथमिक कुंजी" + "डीईएससी टेक्स्ट) बनाएँ";);; } @ ओवरराइड पब्लिक वर्ड ऑनअपग्रेड (SQLiteDatabase डीबी, इंट पुरानावर्सन, इंट न्यूवर्सन) {}}

गतिविधि वर्ग 

  सार्वजनिक वर्ग सरलडेटाबेस गतिविधि को बढ़ाता है {/ * * गतिविधि पहली बार होने पर बुलाया गया। * / @ ओवरराइड सार्वजनिक शून्य पर क्रेट (बंडल सहेजे गए इन्स्टैंसस्टेट) {सुपर। कॉन्टेट (सहेजे गए इन्स्टेंसस्टेट); setContentView (R.layout.main); डीबीएचल्पर डीबीएचलपर = नया डीबीएचलपर (यह); SQLiteDatabase डीबी = dbHelper.getReadableDatabase (); Db.execSQL ("सरलतम मानों में शामिल करें (शून्य, 'परीक्षण');"); कर्सर कर्सर = db.rawQuery ("सिलेक्ट * से SIMPLE_TABLE", रिक्त); टेक्स्टव्यू टेक्स्ट = (टेक्स्टव्यू) ढूंढें वीवीबीआईआईडी (आर.आईड.टेक्स्टबॉक्स); text.setText (cursor.getString (0)); }}

मुझे लगता है कि यह दुर्घटनाग्रस्त हो गया (आवेदन अप्रत्याशित रूप से बंद कर दिया है!) SQLiteDatabase डीबी = ... क्योंकि अगर मैंने कोड को वहां से अंत तक टिप्पणी की तो यह ठीक काम किया। लेकिन मुझे पता नहीं है कि वह ऐसा क्यों करता है। कोई भी मदद की सराहना की जाएगी।

कोई बात नहीं, मुझे पता चला कि मैंने अब क्या गलत किया। 

  db.execSQL ("टेबल बनायें SIMPLE_TABLE (" + "आईडी प्राथमिक कुंजी & lt; कॉमा यहां जाती है;" + "डीईएससी पाठ);");

कॉमाएं गंभीर व्यवसाय हैं I बेवकूफ सवाल के लिए क्षमा करें।

windows - Heroku throws SQLITE3 Read only exception -

-
After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k]) < / Div>
