回答:`execl()` 是一個(gè) Linux 系統(tǒng)編程中的函數(shù),用于執(zhí)行一個(gè)可執(zhí)行文件。它屬于 `exec` 函數(shù)族,其他的函數(shù)包括 `execlp()`、`execvp()`、`execle()`、`execve()` 等。 `execl()` 函數(shù)原型如下: c #include extern char **environ; int execl(const char *path, const ...
回答:給你講一下思路,我當(dāng)時(shí)學(xué)數(shù)據(jù)庫沒了解這個(gè)。一般對(duì)字母的排序都是ASCII值來排序,依次增長。在自定義函數(shù)里面寫一個(gè)比較語句,應(yīng)該就可以啦。
回答:謝邀請(qǐng)!想必你是軟件相關(guān)專業(yè)或者工作的。那么其實(shí)你應(yīng)該看一下三范式,然后區(qū)分部分,完全,傳遞三種依賴方式。好,那你說的部分函數(shù)依賴,其實(shí)就是,設(shè)X,Y是關(guān)系R的兩個(gè)屬性集合,存在X→Y,若X’是X的真子集,存在X’→Y,則稱Y部分函數(shù)依賴于X。舉個(gè)例子:學(xué)生基本信息表R中(學(xué)號(hào),身份證號(hào),姓名)當(dāng)然學(xué)號(hào)屬性取值是唯一的,在R關(guān)系中,(學(xué)號(hào),身份證號(hào))->(姓名),(學(xué)號(hào))->(姓名),(身份證號(hào))...
