推薦：解析DateDiff函數(shù)的語法參數(shù)
描述返回兩個(gè)日期之間的時(shí)間間隔。語法 DateDiff(interval, date1, date2 [,firstdayofweek][, firstweekofyear]]) DateDiff 函數(shù)的語法有以下參數(shù)：參數(shù) 描述 interval 必選項(xiàng)。String expression 表示用于計(jì)算 date1 和 date2 之間的時(shí)間間隔。有關(guān)數(shù)值

1.建立MdbRecordset對(duì)象。MDB數(shù)據(jù)庫是一個(gè)完整的數(shù)據(jù)庫，內(nèi)部可能含有若干個(gè)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,DBPath
　 ’建立Connection 對(duì)象
Set conn = Server.CreateObject
(“ADODB.Connection”)
　 Provider=“Provider=Microsoft.Jet.OLEDB.4.0；”
　 DBPath = “Data Source=” ＆ Server.MapPath(“數(shù)據(jù)庫文件名”)
　 ’打開數(shù)據(jù)庫
　 conn.Open Provider ＆ DBPath
　 Set CreateMdbRecordset = Server.CreateObject(“ADODB.Recordset”)
　 ’打開數(shù)據(jù)表
　 CreateMdbRecordset.Open “數(shù)據(jù)表名”, conn, 2, 2
　 End Function

2.建立帶密碼的MDB數(shù)據(jù)庫的Recordset對(duì)象。它的建立方式與建立不帶密碼的MDB數(shù)據(jù)庫的Recordset對(duì)象類似，只是多了一個(gè)密碼參數(shù)，即在與數(shù)據(jù)庫連接時(shí)，必須給出密碼信息。

Function CreateSecuredMdbRecordset( 數(shù)據(jù)庫文件名, 數(shù)據(jù)表名或Select語句，password )
Dim conn,Provider,DBPath
’建立Connection 對(duì)象
Set conn = Server.CreateObject
(“ADODB.Connection”)
Provider = “Provider=Microsof.Jet.OLEDB.4.0；”
DBPath = “Data Source=”＆ Server.MapPath(“數(shù)據(jù)庫文件名”)
’連接數(shù)據(jù)庫,注意要帶有密碼參數(shù)
conn.Open Provider ＆ DBPath＆“Jet OLEDB:Database Password=”＆assword
Set CreateSecuredMdbRecordset = Server.
CreateObject(“ADODB.Recordset”)
’打開數(shù)據(jù)表
CreateSecuredMdbRecordset.Open “數(shù)據(jù)表名”, conn, 2, 2
End Function

3.DBF文件不是一個(gè)標(biāo)準(zhǔn)的數(shù)據(jù)庫文件，只相當(dāng)于標(biāo)準(zhǔn)數(shù)據(jù)庫文件中的一個(gè)數(shù)據(jù)表，所以為了使用DBF文件，可以把所有的DBF文件放在一個(gè)目錄下，這樣把目錄名看成標(biāo)準(zhǔn)數(shù)據(jù)庫，每一個(gè)DBF文件相當(dāng)于標(biāo)準(zhǔn)數(shù)據(jù)庫中的數(shù)據(jù)表。下面函數(shù)中的Directory是DBF所在的目錄名。

Function CreateDbfRecordset( 目錄名, DBF文件名或Select語句 )
Dim conn,Driver,SourceType,DBPath
’建立Connection 對(duì)象
Set conn = Server.CreateObject
(“ADODB.Connection”)
Driver=“Driver={Microsoft Visual FoxProDriver};” SourceType = “SourceType=DBF;”
DBPath=“SourceDB=” ＆ Server.MapPath(“目錄名”)
’調(diào)用Open 方法打開數(shù)據(jù)庫
conn.Open Driver ＆ SourceType ＆ DBPath
Set CreateDbfRecordset = Server.CreateObject(“ADODB.Recordset”)
’打開DBF文件
CreateDbfRecordset.Open “DBF文件名或Select語句”, conn, 2, 2
End Function

4.由FoxPro生成的DBC數(shù)據(jù)庫與MDB數(shù)據(jù)庫相似，都是一個(gè)數(shù)據(jù)庫包含幾個(gè)數(shù)據(jù)表的形式，所以對(duì)DBC數(shù)據(jù)庫的存取方法與MDB數(shù)據(jù)庫相似。

Function CreateDbcRecordset( DBC數(shù)據(jù)庫文件名, 數(shù)據(jù)表名或Select語句 )
Dim conn,Driver,SourceType,DBPath
’建立Connection 對(duì)象
Set conn = Server.CreateObject
(“ADODB.Connection”)
Driver=“Driver={Microsoft Visual FoxPro Driver};”
SourceType = “SourceType=DBC;”
DBPath = “SourceDB=” ＆ Server.MapPath(“DBC數(shù)據(jù)庫文件名”)
’連接數(shù)據(jù)庫
conn.Open Driver ＆ SourceType ＆ DBPath
Set CreateDbcRecordset = Server.CreateObject(“ADODB.Recordset”)
’打開數(shù)據(jù)表
CreateDbcRecordset.Open“數(shù)據(jù)表名或Select語句”, conn, 2, 2
End Function

5.將Excel生成的XLS文件（book）看成一個(gè)數(shù)據(jù)庫，其中的每一個(gè)工作表(sheet)看成一個(gè)數(shù)據(jù)庫表。

Function CreateExcelRecordset(XLS文件名,Sheet名)
Dim conn.Driver,DBPath
’建立Connection對(duì)象
Set conn = Server.CreateObject
(“ADODB.Connection”)
Driver=“Driver={Microsoft Excel Driver (＊.xls)};”
DBPath = “DBQ=” ＆ Server.MapPath(“XLS文件名”)
’調(diào)用Open 方法打開數(shù)據(jù)庫
conn.Open Driver ＆ DBPath
Set CreateExcelRecordset = Server.CreateObject(“ADODB.Recordset”)
’打開Sheet
CreateExcelRecordset.Open “Select ＊ From [”＆sheet＆“＄]”, conn, 2, 2
End Function

6.SQL Server

Function CreateSQLServerRecordset(計(jì)算機(jī)名稱,用戶ID, 用戶密碼,數(shù)據(jù)庫名稱數(shù)據(jù)表或查看表或Select指令 )
Dim Params, conn
Set CreatSQLServerConnection = Nothing
Set conn = Server.CreateObject
(“ADODB.Connection”)
Params = “Provider=SQLOLEDB.1”
Params = Params ＆ “;Data Source=” ＆ Computer
Params = Params ＆ “;User ID=” ＆ UserID
Params = Params ＆ “;Password=” ＆ Password
Params = Params ＆ “.Initial Catalog=”＆數(shù)據(jù)庫名稱
Conn open Paras
Set CreateSQLServerRecordset = Server.
CreateObject(“ADODB.Recordset")
CreateSQLServerRecordset.Open source, conn, 2, 2
End Function
