Learn SQL Database & Editor

I-SQL Academy: Funda nge-AI wuhlelo lokusebenza lokugcina lweselula lokwazi kahle i-SQL kanye nezisekelo zedathabheyisi. Kungakhathaliseki ukuthi ungumuntu osaqalayo ukuhlola izizindalwazi okokuqala ngqa noma unjiniyela ochwepheshile ofuna ukuthuthukisa amakhono akho emibuzo ye-SQL, lolu hlelo lokusebenza lunikeza indlela ehlakaniphile, eqondisiwe, nesebenza ngezandla yokufunda i-SQL ngezifundo ezisebenzisanayo, izindawo zokuzijwayeza bukhoma, nokusekelwa okunamandla e-AI.

Ulimi Lombuzo Ohleliwe (SQL) luyisisekelo sezinhlelo zedatha yesimanje. Inika amandla yonke into kusukela kumawebhusayithi nezinhlelo zokusebenza zeselula kuya ezinkundleni zezibalo nezinhlelo zokusebenza zebhizinisi. I-SQL Academy yenza ukufunda i-SQL kusebenze futhi kujabulise ngokubuza ngesikhathi sangempela, isizindalwazi esibukhoma sangaphakathi nohlelo, izifundo eziqondene nawe, kanye nosizo oluhlakaniphile oluqhutshwa yi-AI—khona kanye entendeni yesandla sakho.

I-AI-Powered Learning: Funda i-SQL ngejubane lakho ngokusekelwa umfundisi we-AI ohlakaniphile ohlukanisa imiqondo ibe izingcezu ezilumayo, eziqondakalayo. Noma ngabe ufunda izitatimende KHETHA noma uhlola UKUJOYINA okuthuthukile, imibuzo engaphansi, kanye nezinkomba, i-AI ichaza isinyathelo ngasinye, igqamisa imiqondo eyinhloko, futhi ikuqondise ngezibonelo ezisebenzisanayo. Valelisa ezincwadini zokufunda eziyisicefe—lokhu ukufunda ngezandla, okomuntu siqu ngokusemandleni akho.

I-Interactive SQL Editor: Zijwayeze ukubhala imibuzo ye-SQL ngokuqondile kuhlelo lokusebenza usebenzisa i-SQL Editor yethu eyakhelwe ngaphakathi kanye nesizindalwazi esibukhoma. Qalisa imiyalo efana nokuthi KHETHA, FAKA, BUYEKEZA, SUSA, futhi JOYINA futhi ubone imiphumela ngokushesha. Shintsha amathebula, dala izikimu, futhi uzame ngamadathasethi omhlaba wangempela. Konke okwenzayo kwenzeka ngaphakathi kwendawo ephephile, enebhokisi lesihlabathi eziphatha njengenjini yangempela ye-SQL—akukho ukufakwa okudingekayo.

Usizo Lombuzo Ohlakaniphile: Unephutha ku-syntax yakho ye-SQL? I-AI ithola futhi ichaze inkinga, inikeze izilungiso futhi ikusize uqonde ukuthi yini engahambanga kahle nokuthi ungayilungisa kanjani. Kungakhathaliseki ukuthi udonsa kanzima nge-JOIN logic, izigaba ze-GROUP BY, noma imibuzo engezansi, i-AI ayigcini nje ngokulungisa umbuzo wakho—ikusiza ukuthi ufunde ukuthi kungani ukulungisa kusebenza, kuqinise ukuqonda kwakho nekhono.

Ikhodi ye-SQL Ekhiqizwe yi-AI: Udinga usizo ngokubhala umbuzo? Vele ubuze i-AI ngesiNgisi esilula. Ingabe ufuna “ukuthola bonke abasebenzisi ababhalise ngenyanga edlule,” “ukuthola imikhiqizo enenani eliphezulu,” noma “ujoyine ama-oda anamagama amakhasimende”? I-AI ikhiqiza ngokushesha imibuzo ye-SQL ehlanzekile, esebenzayo yemisebenzi yedatha evamile (neyinkimbinkimbi), ongayiqhuba, uyihlaziye, futhi uyilungise ngesikhathi sangempela.

Londoloza futhi Uphinde Uvakashele Imibuzo: Hlela futhi ulondoloze imibuzo yakho eyintandokazi, ukujoyina okuyinkimbinkimbi, namaphethini asebenzisekayo ukuze asetshenziswe esikhathini esizayo. Landela intuthuko yakho kuzo zonke izifundo futhi uzakhele umtapo wakho wezincwadi we-SQL njengoba uhamba. Kungakhathaliseki ukuthi wakha imibiko, amadeshibhodi, noma uphatha idatha, imibuzo yakho elondoloziwe itholakala ngokuthepha nje.

I-Notebook Yokufunda: Thwebula imininingwane, amanothi, nezikhumbuzi ngenothibhukwana eyakhelwe ngaphakathi. Kungakhathaliseki ukuthi i-syntax ye-LEFT JOIN, indlela yokusebenzisa i-GROUP BY, noma amathiphu okuthuthukisa imibuzo, wonke amanothi akho ahlala endaweni eyodwa ukuze asetshenziswe kalula futhi abuyekezwe.

Qedela Ikharikhulamu ye-SQL: I-SQL Academy inikeza indlela ehlelekile ukusuka kwabaqalayo ukuya ezihlokweni ezithuthukile, okuhlanganisa:

Izisekelo ze-SQL: KHETHA, LAPHO, ODA NGE

Ukuhlunga nokufanisa iphethini (LIKE, BETWEEN, IN)

Hlanganisa imisebenzi (COUNT, AVG, SUM, MIN, MAX)

IQEMBU NGOKUNYE NOKUBA

Imibuzo engezansi kanye nemibuzo efihliwe

Ukudala ithebula nokukhohlisa kwedatha (DALA, FAKA, BUYEKEZA, SUSA)

Ubudlelwano kanye NOKUJOYINA (OKUPHAKATHI, KWESOKUNXELE, KWESOKUDLA, NGAPHANDLE OKUGCWELE)

Okhiye abayinhloko nokhiye bangaphandle

Ukwenza inkomba nokushuna kokusebenza

Ukubuka kanye nezinqubo ezigciniwe

Izimvume zomsebenzisi nokuphepha kwesizindalwazi

Izinhlobo zedatha nokujwayelekile

Amasethi edatha omhlaba wangempela kanye nezifundo zezenzakalo

Isifundo ngasinye sihlanganisa ukuvivinya umzimba ngezandla, imibuzo esebenzisanayo, nezinselele ezincane zokuqinisa ulwazi lwakho nokuthuthukisa ukugcinwa.

Izinselele ze-SQL Zesikhathi Sangempela: Qhudelana emhlabeni wonke nabanye abafundi ezinseleleni zemibuzo zomhlaba wangempela. Rarulula izinkinga ezinesikhathi ngokusekelwe kumasethi wedatha wangempela, gibela ibhodi yabaphambili, uzuze amabheji, futhi ucije amakhono akho ngenkathi uzijabulisa.

Kusukela emisebenzini yokuhlanza idatha ukuya ekuhlanganiseni okuyinkimbinkimbi kwamathebula amaningi, lezi zinselele zikugcina umatasa futhi uthuthuka ngokuqhubekayo.
