std::generate用于填充容器中已有元素，需提前分配空間；1.可使用lambda捕獲變量實(shí)現(xiàn)遞增序列；2.可結(jié)合隨機(jī)數(shù)引擎生成隨機(jī)值；3.可通過仿函數(shù)維持狀態(tài)生成如平方數(shù)等序列；生成器需為可調(diào)用對(duì)象，常用于初始化測試數(shù)據(jù)或生成特定序列，使用靈活且簡潔。

要正確處理SQL中的單引號(hào)，需將字符串中的單引號(hào)用兩個(gè)單引號(hào)表示，如'O''Connor'，這是適用于大多數(shù)數(shù)據(jù)庫的標(biāo)準(zhǔn)方法；1.在字符串中使用兩個(gè)單引號(hào)來表示一個(gè)literal單引號(hào)；2.避免依賴反斜杠轉(zhuǎn)義，因其行為依賴數(shù)據(jù)庫模式設(shè)置；3.最佳實(shí)踐是使用參數(shù)化查詢，由數(shù)據(jù)庫驅(qū)動(dòng)自動(dòng)安全地處理轉(zhuǎn)義，防止SQL注入并簡化代碼。
