Qhov no kuj muaj tseeb rau cov ntaub ntawv DDD. Cov no yog cov ntaub ntawv Alpha tsib Cov Ntaub Ntawv Cov Ntaub Ntawv los yog GLBasic 3D Cov Ntaub Ntawv Cov Ntaub Ntawv, tiam sis ob qho ntawm cov qauv no muaj txhua yam ua nrog SQL Cov Lus Txhais Cov Lus Txhais Lus. Ib yam li DLL cov ntaub ntawv, koj xav tau kev pabcuam nkaus kiag los qhib lawv.
Yog hais tias koj tsis tshua muaj DDL cov ntaub ntawv, ces tshawb xyuas cov ntaub ntawv txuas ntxiv nrog rau tom kawg ntawm koj cov ntaub ntawv. Ua li ntawd, koj tuaj yeem paub tias hom ntawv twg yog nyob rau hauv thiab cov kev pabcuam hauv kev software yog sib xws li cov ntaub ntawv ntawd.
Ntau pab nrog DDL ntaub ntawv
Yog tias koj muaj DDL cov ntaub ntawv, tiam sis nws tsis qhib lossis ua haujlwm zoo, saib Kev Pab Ntxiv rau cov ntaub ntawv hais txog kev hu rau kuv ntawm kev tes hauj lwm sib txuas los yog hauv email, luam tawm rau cov kev sib tham hauv kev pabcuam tech, thiab ntau dua.
