      JOIN關鍵字sql語句大全
      使用JOIN關鍵字可以進行連接查詢,它和基本連接查詢一樣都是用來連接多個表的操作。使用JOIN關鍵字可以引導出多種連接方式,如內連接、外連接、交叉連接、自連接等。其連接條件主要通過以下方法定義兩個表在查詢中的關系方式:

      l  指定每個表中要用于連接的目標列。即在一個基表中指定外鍵,在另外一個基表中指定與其關聯的鍵。
      l  指定比較各目標列的值要使用比較運算符,如=、<等。
      使用JOIN關鍵字連接查詢的語法格式為:
      SELECT select_list
      FROM table join_type JOIN table2 [ON join_conditions]
      [WHERE search_conditions]
      [ORDER BY order_expression]
               Table1與table2為基表;join_type指定連接類型,正是該連接類型指定了多種連接方式如內連接、外連接、交叉連接和自連接;join_conditions指定連接條件。
      例如在“網店購物系統”數據庫中“商品信息”和“訂單信息”兩個表中都包含“商品編號”列,用戶可以使用JOIN關鍵字將兩個表建立連接,可以使用下面的語句:
      USE 網店購物系統
      SELECT 商品信息.商品名稱,商品信息.商品價格,訂單信息.交易數量
      FROM 商品信息 JOIN 訂單信息
      ON 商品信息.商品編號 = 訂單信息.商品編號
      WHERE 商品信息.商品價格 < 350
      在上面的語句中,首先在FROM子句中使用JOIN關鍵字將兩個表建立連接,然后通過ON子句給出了連接的條件,最后,使用WHERE子句又給出了連接的限定條件。執行上面語句后,得到如圖5-24所示的結果。
