裡面主要說的是同乙個位址2個不同資料庫之前的操作，a資料庫裡面a表資料有 新增、修改、刪除時，去觸發下面的函式，然後對b資料庫裡面的b表做對應的操作（a表b表結構可以說是相同的）

使用觸發器
觸發器 trigger 是個特殊的儲存過程 一般儲存過程主要通過儲存過程名而被直接呼叫，觸發器則是通過事件觸發執行。觸發器基於乙個表來建立並和乙個或多個資料修改操作 插入 更新或刪除 相關聯，可視作表的一部分。觸發器與資料庫中的表緊密相關，比如當對表執行insert update或delete操作時...
觸發器的使用！
可以定義乙個無論何時用insert語句向表中插入資料時都會執行的觸發器。當觸發insert觸發器時，新的資料行就會被插入到觸發器表和inserted表中。inserted表是乙個邏輯表，它包含了已經插入的資料行的乙個副本。inserted表包含了insert語句中已記錄的插入動作。inserted表...
