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.DSN
oConn.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 DSN
oConn.Open "FILEDSN=/somepath/mydb.dsn;" & _
"UID=Admin;" & _
"PWD=;"
III.ODBC DSN-Less Connections
a)ODBC Text Driver
oConn.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, adCmdText
b)ODBC Driver for Access
i)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 Server
i)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 Oracle
i)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 Databases
i)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 Server
i)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 Oracle
oConn.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 Server
i)ODBC DSN:
oConn.Open "Remote Server=http://carl2;" & _
"Remote Provider=MSDASQL;" & _
"Network Library=DBMSSOCN;" & _
"DSN=Pubs;" & _
"Uid=sa" & _
"Pwd=;"
ii)OLE DB Provider
oConn.Open "Provider=MS Remote;" & _
"Remote Server=http://carl2;" & _
"Remote Provider=SQLOLEDB;" & _
"Network Library=DBMSSOCN;" & _
"Data Source=carl2;" & _
"Initial Catalog=pubs;" & _
"User ID=sa;" & _
"Password=;"
