Ukuba ukhangele indlela elula nesebenzayo yokukhupha idatha kwi-database yangaphandle usebenzisa i-ColdFusion, ukwindawo efanelekileyo. Idatha ingakhutshwa njani kwiidathabheyisi zangaphandle kusetyenziswa iColdFusion? ngumbuzo oqhelekileyo phakathi kwabo bafuna ukwandisa amandla obu buchwepheshe. Ngethamsanqa, iColdFusion ibonelela ngezixhobo ezininzi kunye neempawu ezenza kube lula ukufikelela kunye nokukhupha idatha kuluhlu lwangaphandle. Kweli nqaku, siza kuphonononga inyathelo ngenyathelo ukuba unokwenza njani uninzi lweColdFusion ukuqhagamshela kunye nokukhupha idatha kuluhlu lwangaphandle ngokulula nangempumelelo.

– Inyathelo ngenyathelo ➡️ Ungayikhupha njani idatha kwiziko ledatha langaphandle ngeColdFusion?

• Ekuqaleni, Kufuneka uqwalasele uxhulumaniso kwisiseko sedatha sangaphandle kwifayile yoqwalaselo yeColdFusion.
• Emva koko, Kuya kufuneka udale umbuzo weSQL usebenzisa ithegi kwifayile ye.cfm apho ufuna ukukhupha idatha.
• Emva koko, Umbuzo uyenziwa kusetyenziswa ithegi kwaye iziphumo zabelwe ukuguquguquka.
• Okulandelayo, uyakwazi ukulophu kwiziphumo eziguquguqukayo usebenzisa iluphu ukubonisa idatha kwiphepha lewebhu.
• Ekugqibeleni, Kucetyiswa ukuvala uqhagamshelo lwedatha yangaphandle usebenzisa ithegi ngophawu lwe-dbtype=”ODBC” kunye nokuphumeza=”vala” uphawu.

Imibuzo neempendulo

Imibuzo Ebuzwa Rhoqo malunga nokutsalwa kwedatha kwiColdFusion
