i trying learn best way write queries. understand importance of being consistent. until now, have randomly used single quotes, double quotes, , backticks without real thought. example: $query = 'insert table (id, col1, col2) values (null, val1, val2)'; also, in above example, consider "table," "col[n]," , "val[n]" may variables. what standard this? do? i've been reading answers similar questions on here 20 minutes, seems there no definitive answer question. backticks used table , column identifiers, necessary when identifier mysql reserved keyword , or when identifier contains whitespace characters or characters beyond limited set (see below) recommended avoid using reserved keywords column or table identifiers when possible, avoiding quoting issue. single quotes should used string values in values() list. double quotes supported mysql string values well, single quotes more accepted other rdbms, habit use single quot

in code. have 'no path' option value trigger when selected. have hierachy of no path, mono, stereo, surround. surround being highest option , no path being lowest. what i'm trying have div class triggered if option higher eg. surround. so if option on "surround" , change "stereo" trigger event. the same applies if went "surround" "mono" trigger event because going higher lower. however...if go "mono" "stereo" (or "mono" "surround) not trigger event because going higher option. i have tried manually code got confusing , long , didnt work. it if - changing option less important (or lower than) option selected - trigger event else - don't trigger event. i've trawled through lots of sites , tried piece halfway before stuck. any thoughts on how better? here code: script var hello = ('select option:selected'); alert(hello); $('select').on('change

i have 4 tables: orderforms deliverynota invoices creditnota what make possible link of document other document. example creditnote id 10 linked invoice id 155. orderform 17 linked deliverynote 10. i see 3 possible solutions: create table every link ex.: orderform_link_diliverynote, orderform_link_invoice, orderform_link_creditnote, deliverynote_link_invoice, ... table "document_linking" 5 columns: link_id, orderform_id, deliverynote_id, invoice_id, creditnote_id. table "document_linking" once again 5 cols, in following way: link_id, documentype_one (eg.: invoice, creditnote, ...), document_id_one, document_type_two (eg.: invoice, creditnote, ...), document_id_two i personaly prefer last one, in opinion dynamic solution. if ever add 1 or more doctypes, able without changing document_linking table. other advantage, in opinion, can link documents of thesame type. as don't have experience on kind of linking, ask advice. every kind of welcom

i have global variable needs shared among viewcontrollers. in objective-c, can define static variable, can't find way define global variable in swift. do know of way it? from swift programming guide global variables variables defined outside of function, method, closure, or type context.global constants , variables computed lazily you can define file , can access in current module anywhere. can define in somewhere in file outside of scope.there no need static , global variables compute lazily. var yourvariable = "somestring" and can access anywhere in current module. however should avoid global variables not application state , reason of bugs. as shown in answer in swift can encapsulate them in struct , can access anywhere. can define static variables or constant in swift also.encapsulate in struct struct myvariables { static var yourvariable = "somestring" } you can use variable in class or anywhere let string

the situation this: i created remote branch other remote develop branch -> fetched local -> made changes -> git add -> git commit -> pushed remote , made pull request. pull request still there , branch hasn't been merged yet. is safe delete local branch hasn't been merged yet? i don't want have bunch of local branches don't need anymore. it's technically safe delete local branch once you've pushed remote branch , retrieve changes remote branch, if pull request not merged yet. however, i'd wait until pull request merged. whole idea behind having pull requests, opposed allowing merge want, allow feedback loop between developer , maintainer of project. depends on project's etiquette , level of trust maintainer has towards you, may take several roundtrips of improvements before pull requests merged. i'd avoid hassle of having recreate local branch each time , leave there , work on until request merged.

i use tesseract serial number recognition, want recognize single characters, no word, no dictionary. therefore use 1 of trained tesseract font-types serial number achieve better recognition results. these trained tesseract font-types: andale_mono.ttf arial_black.ttf arial_bold.ttf arial.ttf comic_sans_ms_bold.ttf comic_sans_ms.ttf courier_new_bold.ttf courier_new.ttf georgia_bold.ttf georgia.ttf gottf impact.ttf times_new_roman_bold.ttf times_new_roman.ttf trebuchet_ms_bold.ttf trebuchet_ms.ttf verdana_bold.ttf verdana.ttf since trained font-types have different font-desin styles, there problems in distinguishing example "z" , "2" characters. times new roman has more rounded design, while arial has more straight lines. my experience is, tesseract has problems distinguish "z" , "2" due changed similarity of other font-designs. therefore think can achieve better recognition results, if 1 font-type (for example arial) used character
