Access資料庫多表聯合查詢
access 資料庫多表聯合查詢 1 access 資料庫多表聯合查詢，每次連線之前須將連線符前面的內容放在括號裡面，示例如下 select 表a.欄位1，表b.欄位1，表c.欄位1，表d.欄位1 from 表a inner join 表b on 表a.欄位 表b.欄位 inner join 表c ...
Access資料庫多表連線查詢
第一次在access中寫多表查詢，就按照ms資料庫中的寫法，結果報語法錯，原來access的多表連線查詢是不一樣的 表a b c，a關聯b，b關聯c，均用id鍵關聯 一般寫法 select from a inner join b on a.id b.id inner join c on b.id c...
