      使用EXISTS關鍵字

      sql語句大全

      EXISTS關鍵字的作用是在WHERE子句中測試子查詢返回的行是否存在,如果存在則返回真值;如果不存在則返回假值。使用EXISTS關鍵字的子查詢實際上不產生任何數據,其語法格式為:
      SELECT select_list
      FROM table_source
      WHERE EXISTS|NOT EXISTS(subquery)
      同樣,我們以上面的實例為例,查詢交易數量大于8的會員的會員編號,在這個語句中使用EXISTS關鍵字,如果子查詢中能夠返回數據行即查詢成功,則子查詢外圍的查詢也能成功;如果子查詢失敗,則外圍的查詢也會失敗,這里EXISTS連接的子查詢可以理解為外圍查詢的觸發條件。可以使用下面的語句:
      USE 網店購物系統
      SELECT TOP 3 會員名稱,會員地址,消費總額 FROM 注冊會員
      WHERE  EXISTS
      (SELECT 會員編號 FROM
      訂單信息 WHERE 交易數量 >3)
      執行該語句,得到的結果如圖5-35所示。

      圖5-35  使用EXISTS關鍵字
      使用NOT EXISTS與使用EXISTS相反,當子查詢返回空行或查詢失敗時,外圍查詢成功;當子查詢成功或返回非空行時,外圍查詢失敗。同樣使用上面的實例,只不過將EXISTS換為NOT EXISTS,將子查詢中查詢出交易數量大于7的會員編號,當然這個子查詢肯定失敗,那么得到的結果如圖5-36所示。可以使用下面的語句:
      USE 網店購物系統
      SELECT TOP 3 會員名稱,會員地址,消費總額 FROM 注冊會員
      WHERE NOT EXISTS
      (SELECT 會員編號 FROM
      訂單信息 WHERE 交易數量 >3)

      圖5-36  使用NOT EXISTS子查詢
