i been googling last hour , can not find answer this. i have large text file (1gb) , have file has mapped know on line x line y contains data after. my question how take lines interested in without iterating through lines in file? the main reason interested in doing way performance reasons, imagine quicker take rows 503,432 row 504,432 cycle row 1 504,432 find these rows. any tips appreciated if looking specific row number, need read rows count them anyway. can't count rows without reading file except if lines fixed length. not need save lines when read them. save linenumber need, or handle them without keeping them in memory later.

i have query , when run error message ora-00907: missing parenthesis . when replace case statement either x = g and or y = g and runs expected. select * table1, table2, table3, table4, table5, table6, table7, table8 = b , c = d , e = d , case strfldvar when 'broken_arrow' (x = g) when 'broken_box' (y = g) else -1 end , f = h , = j what doing wrong here? case expression, not predicate (i.e condition) : 'returns' typed value , can not contain predicate result (in then parts). in case (assuming else -1 means 'no match') : and g = case strfldvar when 'broken_arrow' x when 'broken_box' y else null -- never match, if g null end although think simpler replace : and ( (strfldvar = 'broken_arrow' , x = g) or (strfldvar = 'broken_box' , y = g) )

i trying decide http method should used put or post. while looking @ posts on stackoverlflow see this post. one of answers in post says put idempotent, if put object twice, has no effect. nice property, use put when possible. can 1 me out here example. lets have scenario trying create student entry passed in student table in rdbms. so here if try put entry again , again there no effect? in put, you're setting all values of resource, when put done, know state of resource. if wait week , call put again, still know state of resource. a post, contrast, not idempotent - post subset of values. if call post today, wait week, , make same post call again, don't know state of resource - might have changed value you're not setting in post. idempotent means no matter when or how make call, end state of resource same. delete , idempotent.

i have simple tabbar-controller in storyboard. viewcontroller 1 has navigation controller around itself. viewcontroller 2 not have one. viewcontroller 1 shown first when app goes up. i need implement following method: -(void)tabbar:(uitabbar *)tabbar didselectitem(uitabbaritem *)item but cant set delegate of uitabbar. want set deleagte in viewcontroller 1. in ib can show delegate property cant draw line. tried set delegate programmatically. no matter set it, app crashes. have set delegate of uitabbar ? you should make app delegate delegate of tab bar. should able drag tab bar controller in storyboard appdelegate (maybe file's owner). in code, can reference tab bar controller , set tbc.delegate = self in didfinishlaunchingwithoptions: . in both scenarios, make sure first make delegate listen delegate methods adding <uitabbarcontrollerdelegate> interface declaration.

this kinda hard explain. our client wants able add "fictional data" or "ghost data". data shouldn't show unless explicitly defined. able "what if had delivery @ address". (which don't wanna pretend did) my first thought add boolean column tell whether entry ghost entry. means we'd have include constraint every stored procedure. or linq query we've every written , write. not solution. another idea coworker had creating duplicate table containing ghost data. way can keep them separate. problems arise once realize there's relationships table. these has duplicated too. , maintainability takes hit cause every change make in normal table have reflected in "ghost" table. ideas? you can create duplicate tables. - of course every table potentially hold ghost data need seperate table. to around problem relations need joins against unions of real , ghost data. edit: example

i have seen many comments in stack-overflow articles found things either @transactional use @service or @controller "usually, 1 should put transaction @ service layer." "the normal case annotate on service layer level" "think transactions belong on service layer. it's 1 knows units of work , use cases. it's right answer if have several daos injected service need work in single transaction." [source] drawback use @transactional @service layer if had 2 methods example saveuser() , saveemail() (because store emails in database send them later - queue) create in service method saveuserandsendemail(user user) transactional. [source] it means create many methods in service layer instead of 1 save generic method follow public <t> long save(t entity) throws dataaccessexception { session session = sessionfactory.getcurrentsession(); long getgenval=(long) session.save(entity); return getgenval; } acco...

i created default windows forms application project in visual studio 2012. when run program saw width of form can not less 140 pixels. why? , how overcome strange restriction? users wouldn't able use window's minimize, maximize, , close buttons @ top. don't believe can change behaviour sizable formborderstyle. it's usability thing. if remove border, setting none example, can set whatever want programmatically doing: form.width = [...]; you can resize further forms border types: none, fixedtoolwindow, , sizabletoolwindow. toolwindows won't let go below amount well, none let above 2px. set value below that, without getting exception, won't anything.

consider following 2 django models: class item(models.model): ''' represents single item. ''' title = models.textfield() class information(models.model): ''' stores information item. ''' approved = models.booleanfield(default=false) multipurpose_field = models.positiveintegerfield() due way models organized, forced use positiveintegerfield in information referencing item instead of using foreignkey . makes queries more difficult. i select items referenced information instance approved set true . in other words, this: information.objects.filter(approved=true) ...except query return instances of information instead of item referenced in multipurpose_field . i raw sql: select app_item.title app_item left join app_information on app_information.multipurpose_field = app_item.id app_information.approved = 1 is there way without resorting raw sql (which isn't por...
