oracle如何通過存儲(chǔ)過程上傳list保存功能

這篇文章將為大家詳細(xì)講解有關(guān)oracle如何通過存儲(chǔ)過程上傳list保存功能，小編覺得挺實(shí)用的，因此分享給大家做個(gè)參考，希望大家閱讀完這篇文章后可以有所收獲。

一、創(chuàng)建oracle 需要保存的數(shù)據(jù)類型type和存儲(chǔ)過程produce

create TYPE "AL01TYPE"                                                                                                                                                                                                                                  as object
