袖珍数据库连接查询手册关键词：Access, Sql Server, Oracle, ASP, ADO袖珍数据库连接查询手册前言：国庆将近，又加上最近有些网友又非要我们写点什么经验的出来，我只好把我平时使用到的一些数据库连接方式和平时收集到的一些资料拿出来就当给大家的节日礼物把。下面的资料可能不太全，但是可以用来做平时的资料查询用的哦，希望能够帮上大家的忙，呵呵。下面将简单介绍一下几种ADO连接方式：ODBC DSN,ODBC DSN-Less, OLE DB Provider,和"MS Remote" Provider.1。ODBC DSN连接I.DSNoConn.Open "DSN=AdvWorks;" & _ "UID=Admin;" & _ "PWD=;"注意：从MDAC2.1开始就不能够在使用这样的方式了，就是只把DSN文件名放在ConnectString中你必须同时使用DSN，UID，PWD标志。例如下面的方式在MDAC 2.1中将会出错：oConn.Open "AdvWorks"II.File DSNoConn.Open "FILEDSN=/somepath/mydb.dsn;" & _ "UID=Admin;" & _"PWD=;"III.ODBC DSN-Less Connectionsa)ODBC Text DriveroConn.Open _"Driver={Microsoft Text Driver (*.txt; *.csv)};" & _"Dbq=/somepath/;" & _"Extensions=asc,csv,tab,txt;" & _"Persist Security Info=False"注意：需要在SQL语句中指定使用到的文件名。例如：oRs.Open "Select * From customer.csv", _oConn, adOpenStatic, adLockReadOnly, adCmdTextb)ODBC Driver for Accessi)普通安全模式：oConn.Open _"Driver={Microsoft Access Driver (*.mdb)};" & _ "Dbq=/somepath/mydb.mdb;" & _"Uid=Admin;" & _"Pwd=;"ii)如果使用了System database:oConn.Open _"Driver={Microsoft Access Driver (*.mdb)};" & _ "Dbq=/somepath/mydb.mdb;" & _"SystemDB=/somepath/mydb.mdw;", _"admin", ""c)ODBC Driver for SQL Serveri)普通安全模式oConn.Open "Driver={SQL Server};" & _ "Server=carl2;" & _"Database=pubs;" & _"Uid=sa;" & _"Pwd=;"ii)使用信任安全模式：oConn.Open "Driver={SQL Server};" & _ "Server=carl2;" & _"Database=pubs;" & _"Uid=;" & _"Pwd=;"注意：要使用空白的Uid和Pwd d)ODBC Driver for Oraclei)使用现有的Oracle ODBC Driver from Microsoft:oConn.Open _"Driver={Microsoft ODBC for Oracle};" & _"Server=OracleServer.world;" & _"Uid=demo;" & _"Pwd=demo;"ii)使用老版本的Oracle ODBC Driver from Microsoft:oConn.Open _"Driver={Microsoft ODBC Driver for Oracle};" & _"ConnectString=OracleServer.world;" & _"Uid=demo;" & _"Pwd=demo;"IIII)使用微软的OLE DB Data Link Connections方式Data Link File (UDL)a)使用绝对路径oConn.Open "File Name=/somepath/pubs.udl;" b)使用相对路径oConn.Open "File Name=pubs.udl;" V)OLE DB Provider Connections方式a)OLE DB Provider for ODBC Databasesi)Access (Jet):oConn.Open _"Provider=MSDASQL;" & _ "Driver={Microsoft Access Driver (*.mdb)};" & _"Dbq=/somepath/mydb.mdb;" & _"Uid=Admin;" & _"Pwd=;"ii)SQL Server:oConn.Open _"Provider=MSDASQL;" & _ "Driver={SQL Server};" & _"Server=carl2;" & _"Database=pubs;" & _"Uid=sa;" & _"Pwd=;"b)OLE DB Provider for Microsoft Jet (Access)i)普通安全模式：oConn.Open _"Provider=Microsoft.Jet.OLEDB.4.0;" & _"Data Source=/somepath/mydb.mdb;" & _ "User Id=admin;" & _"Password=;"ii)如果使用了System database:oConn.Open _"Provider=Microsoft.Jet.OLEDB.4.0;" & _"Data Source=/somepath/mydb.mdb;" & _ "Jet OLEDB:System Database=system.mdw;", _"admin", "" 注意：当使用OLE DB Provider4.0版本是，需要把MDB和MDW文件转换成4.0的数据库格式iii)如果MDB需要一个数据库密码的话：oConn.Open _"Provider=Microsoft.Jet.OLEDB.4.0;" & _"Data Source=/somepath/mydb.mdb;" & _ "Jet OLEDB:Database Password=MyDbPassword;", _"admin", ""c)OLE DB Provider for Excel Spreadsheet: oConn.Open _"Provider=Microsoft.Jet.OLEDB.4.0;" & _"Data Source=/somepath/expenses.xls;" & _"Extended Properties=""Excel 8.0;HDR=Yes;"";" 注意： "HDR=Yes"表示在第一行中是行标题，在provider中将不把第一行包括入recordset中d)OLE DB Provider for SQL Serveri)普通安全模式：oConn.Open "Provider=sqloledb;" & _ "Network Library=DBMSSOCN;" & _"Data Source=carl2;" & _"Initial Catalog=pubs;" & _"User Id=sa;" & _"Password=;"ii)使用信任安全模式：oConn.Open "Provider=sqloledb;" & _Network Library=DBMSSOCN;" & _"Data Source=carl2;" & _"Initial Catalog=pubs;" & _"Trusted_Connection=yes;"注意："Network Library=DBMSSOCN"声明OLE DB使用TCP/IP替代Named Pipes.e)OLE DB Provider for OracleoConn.Open "Provider=msdaora;" & _"Data Source=OracleServer.world;" & _ "User Id=sa;" & _"Password=;"(VI)Remote OLE DB Provider Connections方式（就是我一直在研究的RDS方式哦，呵呵。）：a)MS Remote - Access (Jet)i)ODBC DSN:oConn.Open "Remote Server=http://carl2;" & _ "Remote Provider=MSDASQL;" & _"DSN=AdvWorks;" & _"Uid=admin" & _"Pwd=;" ii)OLE DB Provider:oConn.Open "Provider=MS Remote;" & _ "Remote Server=http://carl2;" & _"Remote Provider=Microsoft.Jet.OLEDB.4.0;" & _"Data Source=/somepath/mydb.mdb;", _"admin", ""iii)OLE DB Provider自定义事务对象oConn.Open "Provider=MS Remote;" & _ "Remote Server=http://carl2;" & _"Handler=MSDFMAP.Handler;" & _"Data Source=MyAdvworksOLEDBConnectTag;"b)MS Remote - SQL Serveri)ODBC DSN:oConn.Open "Remote Server=http://carl2;" & _ "Remote Provider=MSDASQL;" & _"Network Library=DBMSSOCN;" & _"DSN=Pubs;" & _"Uid=sa" & _"Pwd=;" ii)OLE DB ProvideroConn.Open "Provider=MS Remote;" & _ "Remote Server=http://carl2;" & _"Remote Provider=SQLOLEDB;" & _"Network Library=DBMSSOCN;" & _"Data Source=carl2;" & _"Initial Catalog=pubs;" & _"User ID=sa;" & _"Password=;"
