sql - oracle query returns 4 duplicates of each row -

I'm running an Oracle query. Besides working, it seems that it gives 4 duplicates of each result. Query:

  SELECT * FROM (A *, select the ROWNUM rnum (NEW_USER *, NEW_EHS_QUIZ_COMPLETE.datetime NEW_USER, NEW_EHS_QUIZ_COMPLETE Where exists (NEW_EHS_QUIZ_COMPLETE where SELECT * FROM NEW_USER. .. ID = NEW_EHS_QUIZ_COMPLETE.USER_ID) last_name order by ASC) a where ROWNUM   
 Does anybody know why it is not working properly? 
  
 
 
 You have a cross here: 
 
  SELECT NEW_USER * , NEW_EHS_QUIZ_COMPLETE.DATetime to NEW_USER, NEW_EHS_QUIZ_COMPLETE where exists (* NEW_EHS_QUIZ_COMPLETE Select * NEW_USER.id = NEW_EHS_QUIZ_COMPLETE.USER_ID)  
 
 You probably mean this: 
 
 Select  NEW_USER. *, NEW_USER.id = N EW_EHS_QUIZ_COMPLETE.USER_ID

windows - Heroku throws SQLITE3 Read only exception -

September 15, 2015








    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 -



-



September 15, 2015








    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 -



-



February 15, 2015








    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])
