Mayelana nalolu hlelo lokusebenza

Uhlelo lokusebenza olukuqondisa kuzisekelo zokusebenzisa imiyalo ye-SQL.
Kwethulwa imiyalo ye-SQL yolwazi olu-5 (i-Oracle, i-MySQL, i-SQLServer, i-PostgreSQL, i-SQLite3).

[Sebenzisa]
Uhlelo lokusebenza lomhlahlandlela olukuvumela ukuthi ubheke kalula i-SQL lapho i-SQL iyala imemori yayo ingacaci noma lapho i-SQL iba yiphutha ngasizathu simbe.

-Ungabheka i-SQL ngokubheka emuva kusuka egameni lomyalo nenhloso yokusebenzisa.
Amasampula we-Runtime anikezwa yonke imiyalo.
-Ukuze kusetshenziswe imiyalo esetshenziswa njalo, umsebenzi oyintandokazi wokubhala (inkinobho emise okwenhliziyo) ulula.

Ingasetshenziswa ngokuyimpumelelo ezindaweni zokuthuthukisa lapho i-Intanethi ingenakusetshenziswa khona.
Ingasetshenziselwa nokufunda kwe-SQL lapho uya emsebenzini noma esikoleni.



[Umehluko osesho lwe-SQL nge-Inthanethi]
Inani lemininingwane kulolu hlelo lokusebenza alinakuqhathaniswa uma liqhathaniswa nolwazi lwe-SQL kwi-Intanethi, olunolwazi oluningi kakhulu.
Kodwa-ke, lolu hlelo lokusebenza lunokusebenziseka okuhle okwenzelwe ama-Smartphones, futhi ungabheka kalula i-target SQL.
Ngaphezu kwalokho, ungaguqula i-SQL ehlolwe ngenhloso bese uyiqopha njengememo (irejista njengeyintandokazi).




【Amanothi】
1) Lokhu akulona iqoqo lamasu we-SQL.
Uma ufuna ukuthola ngamasu we-SQL, lolu hlelo lokusebenza alifanele.

2) I-SQL ethunyelwe kungenzeka ingasebenzi.
I-SQL kungenzeka ingasebenzi ngenxa yokwehluka kwemvelo nenguqulo yedatha ngesikhathi sokuqinisekiswa kokusebenza.
