為什麼sql注入的時候會寫union select 1,2~~~~~from admin
我也是最近好奇才去學了一點web滲透的知識。在這之前還是需要一定的資料庫的相關知識。這裡假設知道當前表有多少列(這裡設定為10),也可以直接通過order by直接測試出來。union 是聯和查詢的一個關鍵字,這個有一個前提就是必須滿足所有的列是相同的,所以在這前面必須要新增

通過非聚集索引讓select count(*) from 的查詢速度提高几十倍、甚至千倍
通過非聚集索引,可以顯著提升count(*)查詢的效能。 有的人可能會說,這個count(*)能用上索引嗎,這個count(*)應該是通過表掃描來一個一個的統計,索引有用嗎? 不錯,一般的查詢,如果用索引查詢,也就是用Index Seek了,查詢就會很快。
