Iqukethe izikhangiso

Mayelana nalolu hlelo lokusebenza

Ufuna ukufunda i-SQL kodwa ukhathele izifundo zethiyori? I-SQL Gym ikuvumela ukuthi uzijwayeze kusukela ngomzuzu wokuqala.

Bhala imibuzo yangempela ngokumelene nesizindalwazi sesitolo esingelona iqiniso (amakhasimende, imikhiqizo, nama-oda) bese uthola ukuqinisekiswa okusheshayo. Awekho amaseva, akukho ukubhaliswa, akukho uxhumano lwe-inthanethi.

Indlela esebenza ngayo

Uqhubeka ngendlela yokufunda ehlelekile kumamojula ama-5:

• KHETHA — ithola idatha oyidingayo
• LAPHO — ihlunga imigqa enemibandela
• ODA NGO- — ihlela imiphumela yakho
• IQEMBU NGO- — ihlanganisa futhi ifingqa idatha
• JOYINA — ihlanganisa ulwazi oluvela kumathebula amaningi

Ukuzivocavoca ngakunye kukunikeza inkinga yangempela yebhizinisi: "Yimiphi imikhiqizo emi-5 ethengiswa kakhulu?" noma "Yimaphi amakhasimende abeke ama-oda angaphezu kwama-3?" Ubhala umbuzo, uhlelo lokusebenza luyawenza futhi lukutshele ukuthi ulungile yini ngokuqhathanisa imiphumela — hhayi i-syntax.

Izici Eziyinhloko

✓ Izivivinyo ezingama-20 eziqhubekayo, ezihlelwe ngomqondo

✓ Imodi ye-Sandbox yokuhlola isizindalwazi samahhala
✓ Umhloli weskimu ohlanganisiwe: amathebula emibuzo namakholomu nganoma yisiphi isikhathi
✓ Uhlelo lokuqhubekela phambili olunokuvula kancane kancane kokuzilolonga
✓ Isebenza ngo-100% ungaxhunyiwe ku-inthanethi — konke kusebenza kudivayisi yakho
