i having problems in recalculating running totals. i have situation have duplicate transactions , these must deleted , and initial , closing balance must recalculated based on amount , taking account when isdebit. my attempt have nested cursors (parent-child) , parent select distinct bookingno , child calculation looks messy , didn't work, didn't post because didn't want confuse things. i know in sql server 2012 can use ( sum on partition by ) cannot figure how handle deleted row etc.. below did far --create table testing if object_id(n'testtransaction', 'u') not null drop table testtransaction go create table [testtransaction] ( [id] [bigint] identity(1,1) not null, [bookingno] [bigint] not null, [isdebit] [bit] not null, [amount] [decimal](18, 2) not null, [initialbalance] [decimal](18, 2) not null, [closingbalance] [decimal](18, 2) not null ) on [primary] go i

found interesting issue quick search if single character search, 25 characters work fine, 1 doesn’t – “n” quick search select of form: select* some_full_text_table contains(the_full_text_field, ' "n*" ') this should search full text field in table beginning “n”. example data rows: “name1 foo bar cardiac” “aname foo2 echo” “some name foo3 ct” “the requested letter” the query should return rows 1 , 3 1 have words begin “n”. the actual result rows returned, row 4, has no n’s @ all. i believe sql bug. “na*” works expected , returns 1 , 3. looking solution or work around here example sql 2014 create table testfulltextsearch ( id int not null, alltext nvarchar(400) ) create unique index test_tfts on testfulltextsearch(id); create fulltext catalog ftcat_tfts; create fulltext index on testfulltextsearch(alltext) key index test_tfts on ftcat_tfts change_tracking auto, stoplist off go /* no n's in data */ insert testfulltextse

i have form people can fill in there details , share current timetable. go , find times suit people , sort them groups. currently php form prints variable either 'work' or 'free' (based on selection in form) table , send email contact details , timetable. is possible assign text color or cell color value particular cell of table, when sending form? (so when receive email cells have 'free' variable in them colored green etc.) <?php $name_f = $_post['name_f']; $name_l = $_post['name_l']; $phne = $_post['phne']; $cont_em = $_post['cont_em']; $mon09to10h = $_post['mon09to10h']; $tue09to10h = $_post['tue09to10h']; $wed09to10h = $_post['wed09to10h']; ... $to = "email@email.com"; $subject = "new message"; ... $message = <<<eod new form submitted<br><br> <b>name:</b> $name_f $name_l <br> <b>phone:</b> $phne <br>

it possible me rename namespace of entire project (including of course: dbcontext class, migrations configuration classes, etc) without breaking or having recreate migrations? say, have project myproject, namespace is foo.myproject and configuration classes in foo.myproject.migrations say want rename foo namespace bar , , of course configurations namespace be bar.myproject.configurations is there correct way of doing , maintain current migrations still working? these ways involve manually editing ___migrationhistory table or something? (at glance see contextkey column, suspect should manually edit.) yes, indeed need update contextkey in the__migrationhistory table. code: update [dbo].[__migrationhistory] set [contextkey] = 'new_namespace.migrations.configuration' [contextkey] = 'old_namespace.migrations.configuration' a read on topic of renaming namespaces ef6: http://jameschambers.com/2014/02/changing-the-namespace-with-entity-fr

if associative array exists in python3, waste check if element of exists rather using it? should you: if 'name' in array , not array['name'].startswith('something'): or should just: if not array['name'].startswith('something'): ... , python3 handle "for" you? you can - if not array.get('name', 'something').startswith('something'): get() function returns second value default if key ( name ) not found. so in above case , return something , if key not found in dictionary, , because of .startwith() , not , complete conditional expression evaluate false , doing in op's first example .

if knows secret key , alters lets example username of json token , expiry time, able access secured data on sever? you need 5 different parameters access token - grant_type, username, password, client_id, client_secret so, knowing secret key, username not token; knowing password get. precisely means token if he/she knows parameters, else not!

we have "erp like" project use_tz = false in our settings , set time_zone desired zone requested each client, since each client different site (each client has it's own wsgi proccess , settings file) but moving django tenants (it gets hostname in middleware , changes db schema according it). , 1 settings file rule them all. trying emulate previous behavior wrote middleware change timezone using django.utils.timezone.activate if call datetime.datetime still getting time using settings.time_zone instead "activated" timezone. how should dealing timezone in scenario? additional info: it important same timezone user on same subdomain(tenant) independently of location of each user. we using postgresql timestamp time zone fields. al operations should remain date/time have.

i have string like: "water water asdf fdsa" as strings like: "water water asdf fdsa water" i need remove first instance of back substrings these 2 cases become: "water asdf fdsa" , "water asdf fdsa water" what tried do: list<string> substrings = findsubstrings(returnstring); ienumerable<string> duplicateitems = x in substrings group x x grouped grouped.count() > 1 select grouped.key; so have seperate findsubstrings method returns list contains substrings original string. (from online found) way detect duplicates list of them placed in ienumerable. is best way go like: (int = 0; < substrings.count; i++) { //if duplicateitems contains substring , substring[i+1] same item, remove it) } the issue cant string duplicateitems if contains more 1 duplicate substring

here resource definition: app.factory('program', ['$resource', function ($resource) { return $resource(host + '/rest/program/:id/:action', {}, {query: {method: 'get', isarray: false}}); }]); when call program.save({id:3,name:'foo'}); sends request post /rest/program , places {id:3,name:'foo'} in request body. shouldn't send update request /rest/program/3 , put {name:'foo'} in request body. try this: app.factory('program', ['$resource', function ($resource) { return $resource(host + '/rest/program/:id/:action', { id: '@id', action: '@action' }, { query: { method: 'get', isarray: false } }); }]); you might need pass them parameters too.

okay, know following 2 lines equivalent - (0 == i) (i == 0) also, first method encouraged in past because have allowed compiler give error message if accidentally used '=' instead of '=='. my question - in today's generation of pretty slick ide's , intelligent compilers, still recommend first method? in particular, question popped mind when saw following code - if(dialogresult.ok == messagebox.show("message")) ... in opinion, never recommend above. second opinions? i prefer second one, (i == 0), because feel more natural when reading it. ask people, "are 21 or older?", not, "is 21 less or equal age?"

i working off .net website has bunch of webforms. user types in data via browser , submitted data pushed sql server database. i trying analyze data in database struggling because there no code book shows me codes 1, 2, 3 etc represent. is there relatively simple tool in javascript or can use extract options in dropdown list , tell me how coded ? instance, right-clicking on source code can see mode: there 3 options: 1=research, 2=test , 3=non-research . i've got couple of hundred of these things not want hand... i thinking there tools (hopefully online, maybe jsfiddle) can automatically. i have copied snippet of html below. not know if helps page uses: bootstrap.js jquery.js some css <tr> <th class="newpatient-label">mode: </th> <td> <select name="ctl00$cphbody$fvpatient$modedropdownlist" id="cphbody_fvpatient_modedropdownlis

i have ransack form on project inherited looks this: <%- ransack_form_options ||= {} -%> <%- search_field_options ||= {} -%> <%- search_field_options.merge! autocomplete: "off", id: "q" -%> <div class="search-form"> <%= search_form_for(@q, ransack_form_options) |f| %> <%= f.text_field search_on, search_field_options %> <%= f.submit 'search' %> <%= button_tag '', class: 'cancel-search' %> <% end %> </div> the value of search_on student_first_name_or_student_last_name_or_student_email_cont . this works searching first name or last name or email. if want search full name or first name or last name or email? how can that?

this not 'pure' functional question involves side-effects. have function may take 10 seconds, complete. function generates data in database (for example). if run twice @ same time create duplicate data. lets function can triggered clicking button in browser. if 2 people click within seconds of each other function can running twice concurrently. in java , similar systems use synchronise on semaphore. in node or django can take advantage of single threading drop parallel runs. running = false def long_running_process(): global running # run once if running: return try: running = true .... go ... finally: running = false the requirement in python global reference clear hint function requires state - , imperative nature. so, questions. how 'pure' functional programs demand immutability handle problem? and how implement in python (for example)? is best option use reactive python library? i know haskell people tell me create state

when change translations keeping previous value not new one. first, have file #: choices/__init__.py:14 msgid "power on" msgstr "encendido" then, changed this #: choices/__init__.py:14 msgid "power on" msgstr "dispositivo encendido" i compile messages, translation not updated. happens translation not all. in development mode, not behind ningx. restart runserver. what reason? that because of app loading order. if app, defined later in installed_apps defines different translation same literal.

if have model: class model(models.model): variable_name = value variable_name2 = models.fieldtype(default=value) what's difference; first 1 allowed? kind of variable that? i.e count = 2 vs count = models.integerfield(default=2) follow question i know inherently goes against constant variables there variable shared among instances still editable? static/constant variables seem shared among instances definition seems must defined in code; instead of user input want. class dog(models.model): var = 10; # static variable, want changeable in admin instance = dog(____) # var = 10 as @nightshadequeen said, models.*field fields saved database. other constant. as second question, no there not. constant , while can change it, remain changed scope of instance. here's example of mean: class example(models.model): variable_name = 5 def description(): instance_a = example() instance_a.variable_name == 5 # true instance_a.variable_name = &#
