Marton Greber

Mayelana nalolu hlelo lokusebenza

Funda i-SQL ngezikhathi zansuku zonke zemizuzu eyi-15 — efonini yakho, noma kuphi.

Ukuzijwayeza kwe-SQL kuguqula izikhathi zokungasebenzi zibe ukuqeqeshwa kwamakhono edatha okusebenzayo. Ngokuzivivinya okusebenzisanayo, amasethi edatha angempela, kanye nempendulo esheshayo, uzokwakha ukuzethemba kwe-SQL kusukela ezisekelweni zabaqalayo kuya kumakhono okulungela ingxoxo — khona kanye efonini yakho.

Kungokwabani:
- Abashintshi bemisebenzi abangena kwezobuchwepheshe
- Ochwepheshe bengeza i-SQL kuthuluzi labo lamathuluzi
- Abafundi balungiselela izingxoxo zobuchwepheshe
- Noma ubani othanda ukwazi ngedatha kanye nezizindalwazi

Kungani kuhlukile:
- Idatha yangempela: ukuzijwayeza ngezimo ezingokoqobo
- Ikharikhulamu eqhubekayo: qala elula, wakhele imibuzo eyinkimbinkimbi
- Umklamo weselula-kuqala: funda noma kuphi, noma nini
- Qonda amaphutha futhi uthuthukise ngokushesha
- Intuthuko ehlanganisiwe: imigqa, i-XP, kanye nempumelelo ukuze uhlale uhambisana

- Ukuhlanganiswa (COUNT, SUM, AVG…)
- Imibuzo engezansi kanye namasu athuthukile
- Imiqondo yokuklama isizindalwazi esiyinhloko

Hlala ubambekile:
- Izinselele zokuzijwayeza zansuku zonke
- Ukuzijwayeza okuqondiwe ngesihloko
- Imodi eqinile yabasebenzisi abanamandla
- Izibalo zentuthuko ezinemininingwane
- Impumelelo

Qala uhambo lwakho lwedatha namuhla - akukho sipiliyoni sokubhala ikhodi sangaphambilini esidingekayo, imizuzu eyi-15 nje yelukuluku.
