      查詢

      一. 查詢的基礎知識

      所謂查詢是指根據用戶指定的一個或多個條件,在數據庫中查找滿足條件的記錄,并將其作為文件存儲起來。
      在Access中,查詢是一個特殊的文件,它是數據庫中的一種組件,其目的是以一定的結構存儲用戶檢索到的一組數據。用戶通過查詢告訴Access檢索條件,Access根據用戶提供的條件將查詢到的數據反饋給用戶。

      1. 查詢的類型

      選擇查詢:是最常用的查詢方法,它的作用是根據用戶提供的條件,從一個或多個數據表中檢索數據,并且在數據表中顯示結果。
      參數查詢:是一種動態查詢,在建立查詢時為用戶留有動態參數接口。在執行時顯示“輸入參數值”的對話框,提示用戶根據當時需要輸入參數信息,然后再檢索相應的記錄。再次執行該查詢時,輸入其他參數信息,就會得到另外一組數據。
      匯總查詢:在選擇查詢的基礎上對數據進行分組,并且對查找到的數據記錄進行總計、計數、求平均以及其他類型的統計計算。
        交叉表查詢:可以顯示來源于表中某個字段的統計值(求和、平均等),并將它們分組,分別列在數據表的左側和上方,構成一個二維表格。
      動作查詢:在數據表中,用戶一次只能修改一處數據,而在查詢中,用戶一次可以根據條件修改、刪除多處數據或者增加一組記錄,還可以利用一個或多個表中的全部或部分數據創建新表。
      *   刪除查詢--從一個或多個表中刪除一組記錄。
      *   更新查詢—將一個或多個表中的記錄做全局性的修改。
      *   追加查詢--從一個或多個表中將一組記錄添加到另一個表的末尾。
      *   生成表查詢--利用一個或多個表中的全部或部分數據創建一個新表。
      SQL查詢:使用標準的SQL語句創建的查詢
       

       2. 查詢的作用

      *進行了查詢操作以后,Access將檢索到的數據存入一個動態數據集中,供用戶瀏覽和分析,用戶對其做的修改將直接存入到對應的表中。
      *可將查詢得到的結果用作窗體和報表的數據來源。每次打開窗體或打印報表時,該查詢從數據表中檢索最新數據,供窗體或報表使用。用戶也可以在基于查詢的窗體上直接輸入或修改數據,這些記錄內容的變化將引起查詢內容的變化,并且通過查詢反映到數據表中。
      *  計算字段--在查詢中除了選擇表中的字段以外,還可以建立一些新的字段,并用這些字段保存計算結果,這樣的字段被稱為計算字段。
