Ngakho-ke, yini Idethi ye-Diff Sql, futhi kungani kubalulekile? Idethi ye-Diff Sql kuwumsebenzi we-SQL obala umehluko phakathi kwezinsuku ezimbili. Umqondo olula, kodwa ongaba nomthelela obalulekile endleleni esihlaziya ngayo futhi esikhohlisa ngayo idatha. Noma ngabe ungusosayensi wedatha, umhlaziyi webhizinisi, noma unjiniyela, Idethi ye-Diff Sql iyithuluzi elibalulekile kukhithi yakho yamathuluzi.
Kulokhu okuthunyelwe kwebhulogi, ngizohlola umhlaba we Idethi ye-Diff Sql futhi sikubonise ukuthi ingasetshenziswa kanjani ukuguqula ukuhlaziywa kwedatha yakho. Sizongena esimeni somhlaba wangempela futhi sibone ukuthi kanjani Idethi ye-Diff Sql ingasetshenziswa ukuxazulula inkinga evamile. Futhi, kunjalo, sizohlola izinzuzo nemikhawulo ye Idethi ye-Diff Sql, ukuze ukwazi ukwenza izinqumo ezinolwazi mayelana nokuthi uzoyisebenzisa nini.
Kuyini Idethi ye-Diff Sql nethi Kungani Kubalulekile?
Idethi ye-Diff Sql kuwumsebenzi we-SQL obala umehluko phakathi kwezinsuku ezimbili. Umqondo olula, kodwa ongaba nomthelela obalulekile endleleni esihlaziya ngayo futhi esikhohlisa ngayo idatha. Noma ngabe ungusosayensi wedatha, umhlaziyi webhizinisi, noma unjiniyela, Idethi ye-Diff Sql iyithuluzi elibalulekile kukhithi yakho yamathuluzi.
Ngakho, kungani Idethi ye-Diff Sql kunendaba? Nokho, okokuqala, ikuvumela ukubala kalula umehluko phakathi kwezinsuku ezimbili. Lokhu kungaba usizo ezimweni ezihlukahlukene, ezifana nokubala iminyaka yekhasimende, ukucacisa ubude besikhathi sephrojekthi, noma ukuhlonza amathrendi kudatha.
Kodwa Idethi ye-Diff Sql ingaphezu kokubala nje okulula. Kuyithuluzi elinamandla elingasetshenziswa ukuguqula ukuhlaziywa kwedatha yakho. Ngokusebenzisa Idethi ye-Diff Sql, ungathola imininingwane ngedatha yakho obungeke ukwazi ukuyithola ngenye indlela. Ngokwesibonelo, ungasebenzisa Idethi ye-Diff Sql ukuhlonza amaphethini ekuziphatheni kwamakhasimende, ukulandelela ukuqhubeka kwephrojekthi, noma ukuhlaziya umthelela womkhankaso wokumaketha.
Isimo Somhlaba Wangempela: Ukuguqula Idethi ye-Diff Sql Yempumelelo
Ake sithi ungumphathi wokumaketha enkampanini yokudayisa. Unikezwe umsebenzi wokuhlaziya umthelela womkhankaso wakamuva wokumaketha ekuthengisweni. Unedathasethi ehlanganisa amadethi omkhankaso, kanye nedatha yokuthengisa yesikhathi sangaphambi nangemuva komkhankaso.
Ukuhlaziya idatha, ungasebenzisa Idethi ye-Diff Sql ukubala umehluko phakathi kwamadethi omkhankaso kanye nedethi yedatha yokuthengisa. Lokhu kuzokuvumela ukuthi ukhombe ubude besikhathi somkhankaso kanye nomthelela obe nawo ekuthengisweni.
Kodwa akugcini lapho. Ngokusebenzisa Idethi ye-Diff Sql, ungase futhi usebenzise idatha ukuhlonza amaphethini ekuziphatheni kwekhasimende. Isibonelo, ungasebenzisa idatha ukukhomba ukuthi yiziphi izinsuku zeviki noma yiziphi izikhathi zosuku ezibone ukuthengiswa okuningi. Lolu lwazi lungasetshenziselwa ukwazisa imikhankaso yokumaketha yesikhathi esizayo futhi kuthuthukiswe ukusebenza kahle kwayo.
Ngakho-ke, ungayisebenzisa kanjani Idethi ye-Diff Sql ukuze uguqule ukuhlaziywa kwedatha yakho? Nawa amathiphu ambalwa:
