Indawo yokufaka

Inkqubo yethu yobungcali. Ke ngoko, ungasebenzisa iintlobo ezahlukeneyo zamasimi ukufaka ulwazi olwahlukileyo. Iinkalo zokungeniswa kwedatha ziyahluka zombini ngenkangeleko kunye nenjongo yazo. Indawo yokungena kwedatha inokuba yinto elula okanye ibandakanye amaqhosha ongezelelweyo.

Imimandla yokufaka kuwo onke amaxesha

Indawo yokufaka umbhalo

Kwindawo yokubhaliweyo , ngenisa nawuphi na umbhalo usebenzisa ibhodi yezitshixo. Umzekelo, xa ucacisa "igama lomsebenzi" .

Indawo yamanani
Ungangenisa kuphela inani kwindawo yamanani . Amanani anokuba yinani elipheleleyo okanye ngamaqhezu. Kumanani amaqhezu, inani elahlukileyo lamagama liboniswa emva kwesahluli secandelo elipheleleyo ukusuka kwi-fractional. Isahluli sinokuba lichaphaza okanye isiphumlisi.
Xa usebenza kunye "ubungakanani" imveliso yezonyango, uya kuba nako ukungena ukuya kuthi ga kwidijithi ezintathu emva kwedelimiter. Uza kungena nini "izixa zemali", ngoko ke abalinganiswa ababini kuphela abaya kuboniswa emva kwechaphaza.

Uluhlu lwamaxabiso
Ukuba kukho iqhosha elinotolo olusezantsi, ngoko unoluhlu oluhlayo lwamaxabiso.
1. Uluhlu lunokulungiswa , apho ungenako ukukhankanya naliphi na ixabiso elingenasizathu.
2. Uluhlu lunokuhlelwa , ngoko awukwazi ukukhetha kuphela ixabiso kuluhlu, kodwa ungenise elinye elitsha kwibhodi yezitshixo.
  Olu khetho luluncedo xa ukhankanya "isikhundla somsebenzi" . Uya kukwazi ukukhetha indawo kuluhlu lwezifakwe ngaphambili, okanye ufake indawo entsha ukuba enye ayikaboniswa.
  Kwixesha elizayo, xa ufaka omnye umqeshwa, isithuba esifakiweyo ngoku siya kuvela nako kuluhlu, kuba inkqubo yengqondo ye-'USU' isebenzisa oko kubizwa ngokuba 'zizintlu zokuzifundela'.
Jonga indlela yokusebenzisa uphendlo kuluhlu lwamaxabiso okufakwayo kwendawo .

Ukukhetha kuluhlu
Ukuba kukho iqhosha eline-ellipsis, ngoko le yintsimi yokhetho kulawulo . IN "intsimi enjalo" Ukufaka idatha kwibhodi yezitshixo akuyi kusebenza. Kuya kufuneka ucofe iqhosha, emva koko uya kuzifumana kuluhlu olufunekayo. Apho ungakhetha ixabiso esele likho okanye wongeze elitsha.
Jonga indlela yokuchaneka ngokuchanekileyo nangokukhawuleza ukukhetha kwincwadi yereferensi .
Kwenzeka ukuba ukhetho oluvela kulawulo lwenziwa kusetyenziswa uluhlu oluhlayo. Oku kwenziwa xa kubaluleke kakhulu ukukhetha ngokukhawuleza ixabiso kunokukwazi ukongeza into engekhoyo kumxholo. Umzekelo uya kuba sisikhokelo "Iimali" , kuba kunqabile kakhulu uya kungena kwimarike yesinye ilizwe kwaye wongeze imali entsha. Amaxesha amaninzi, uya kukhetha ngokulula kuluhlu oluhlanganiswe ngaphambili lweemali.

Indawo yokufaka iintambo ezininzi
Kukwakho nemimandla yokufaka yemigca emininzi apho ungangena khona "umbhalo omkhulu" .

Intsimi yeBoolean
Ukuba akukho magama afunekayo, ngoko i ' iflegi ' iyasetyenziswa, enokwenziwa okanye ingasebenzi. Umzekelo, ukubonisa ukuba umsebenzi othile sele ekhona "ayisebenzi" wena, nqakraza nje.

Umkhethi womhla
Ukuba ufuna ukucacisa date , unokuyikhetha usebenzisa ikhalenda yotsalo-phantsi eluncedo, okanye uyingenise kwibhodi yezitshixo.
Ngaphezu koko, xa ufaka ixabiso kwikhibhodi, awukwazi ukubeka amanqaku ahlulayo. Ukukhawulezisa umsebenzi wakho, inkqubo yethu iya kongeza yonke into oyifunayo ngokwayo. Ungabhala unyaka ngoonobumba ababini kuphela, okanye ungayibhali kwaphela, kwaye emva kokungena usuku nenyanga, cinezela u ' Ngena ' ukuze udweliso lwenkqubo lususe ngokuzenzekelayo unyaka wangoku.
Kukho neendawo zokungena kwixesha . Kukho kwakhona umhla kunye nexesha kunye.

Indawo yokulungelelanisa
Kunokwenzeka ukuba uvule imephu kwaye ucacise ulungelelwaniso emhlabeni , umzekelo, indawo "umonde" .

Jonga indlela yokusebenza ngemephu .

Ukukala
Omnye ummandla onomdla onokubakho kumnqongo womthengi xa uceliwe ngu ' Umlinganiselo '. Ungabonisa isimo sakho sengqondo kumxhasi ngamnye ngenani leenkwenkwezi.

Ikhonkco
Ukuba umhlaba ufomathwe njenge ' ikhonkco ', ngoko unokulandelwa. Umzekelo omkhulu yintsimi "I-imeyile" .
Ukuba ucofa kabini kwidilesi ye-imeyile, ngoko uya kuqalisa ukudala ileta kwinkqubo yeposi.
Xa kufuneka kubhekiselelwe kwezinye iifayile , inkqubo yeUSU inokuphumeza oku ngeendlela ezahlukeneyo.
- Ungagcina ikhonkco kuyo nayiphi na ifayile ukuba awufuni ukuba i-database ikhule ngokukhawuleza.
- Okanye khuphela ifayile ngokwayo, ukuze ungakhathazeki ngokulahlekelwa yiyo.
Ipesenti
Kukho ngamanye amaxesha i ' field-percent '. Ayigcwaliswanga ngumsebenzisi. Ibalwa yinkqubo ye -USU ngokwayo ngokwe-algorithm ethile. Ngokomzekelo, kwimodyuli yezigulane, unokwenza intsimi eya kubonisa ukuba idatha epheleleyo ifakwe ngabalawuli malunga nomntu ngamnye.

Ukukhetha umbala
Yile ndlela intsimi yokukhetha umbala ibonakala ngayo, iphinda idalwe ukuba iyalele ukuba kuyimfuneko.
Iqhosha loluhlu oluhlayo likuvumela ukuba ukhethe umbala kuluhlu. Kwaye iqhosha le-ellipsis libonisa ibhokisi yencoko yababini epheleleyo ngombala wombala.
Ifestile inokuba nembono ehlangeneyo kunye neyandisiweyo. Imboniselo eyandisiweyo iboniswa ngokunqakraza ku ' Chaza umbala ' iqhosha ngaphakathi kwebhokisi yencoko yababini ngokwayo.

Umfanekiso
Indawo yokufaka umfanekiso inokufumaneka, umzekelo, "Apha" .
Funda ngeendlela ezahlukeneyo zokulayisha umfanekiso .
