回答:WITH AS短語,也叫做子查詢部分(subquery factoring),可以讓你做很多事情,定義一個SQL片斷,該SQL片斷會被整個SQL語句所用到。有的時候,是為了讓SQL語句的可讀性更高些,也有可能是在UNION ALL的不同部分,作為提供數據的部分。 特別對于UNION ALL比較有用。因為UNION ALL的每個部分可能相同,但是如果每個部分都去執行一遍的話,則成本太高,所以可以使...
回答:只有你努力 堅持 堅持 就們沒有問題。我本人33歲轉Java開發從hello world開始 。10年過去已經是加拿大一家公司CTO 但天天仍然寫代碼。為了第一份開發工作 把整本英文版java core,設計模式,算法 oracle oca 全部背下來 手機里也裝了 沒事就背誦 理解 。不理解的立馬上機寫代碼。天天白板手寫算法。沒有工作就到處求人免費幫人做系統。激情燃燒的歲月。所謂歲數精力不夠我個...
回答:說一句潑涼水打擊的話,自由職業者做編程一點前途沒有,趁早打消這樣的念頭。主要原因是你搞不到賺錢的項目。軟件開發不同于送外賣,會騎摩托、能認識門牌號就可以;軟件開發者做的軟件首先要得到認可,有人愿意用,愿意掏錢。回到正題。不同方向,使用工只不一樣。互聯網、AI、手機應用開發,先選方向,再決定用VS、JAVA還是Python等工具。
