      推薦:解析ASP中連接各種類型數(shù)據(jù)文件的方法
      1.建立MdbRecordset對象。MDB數(shù)據(jù)庫是一個完整的數(shù)據(jù)庫,內(nèi)部可能含有若干個數(shù)據(jù)表,在此函數(shù)中,Connection的作用是連接數(shù)據(jù)庫,Recordset的作用是打開數(shù)據(jù)表。 Function CreateMdbRecordset(數(shù)據(jù)庫文件名, 數(shù)據(jù)表名或Select語句 ) Dim conn,Provider,DBPat

      顯示形式:
               ID     NAME      |    ID   NAME
               1       JULIET    |    2     PALYBOY
               3       BABY      |    4     TOM
               5       LENA      |    6      JERY
       首頁 前頁 后頁 尾頁  頁數(shù):1/4  6條/頁   總記錄數(shù):25條
