澳门新葡亰集团:袖珍数据库连接查询手册



下面的资料可能不太全,然则可以用来做日常平凡的资料查询用的哦,盼望能够帮上大年夜家的忙,呵呵。

下面将简单先容一下几种ADO连接要领: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=;"

留意:从MDAC2.1开始就不能够在应用这样的要领了,便是只把DSN文件名放在ConnectString中

你必须同时应用DSN,UID,PWD标志。例澳门新葡亰集团如下面的要领在MDAC 2.1中将会掉足:

oConn.Open "AdvWorks"

II.File DSN

oConn.Open "FILEDSN=\somepath\mydb.dsn;" & _

"UID=Admin;" & _

"PWD=;"

III.ODBC DSN-Less Connections

a)ODBC T澳门新葡亰集团ext Driver

oConn.Open _

"Driver={Microsoft Text Driver (*.txt; *.csv)};" & _

"Dbq=\somepath\;" & _

"Extensions=asc,csv,tab,txt;" & _

"Persist Security Info=False"

留意:必要在SQL语句中指定应用到的文件名。例如:

oRs.Open "Select * From customer.csv", _

oConn, adOpenStatic, adLockReadOnly, adCmdText

b)ODBC Driver for Access

i)通俗安然模式:

oConn.Open _

"Driver={Microsoft Access Driver (*.mdb)};" & _

"Dbq=\somepath\mydb.mdb;" & _

"Uid=Admin;" & _

"Pwd=;"

ii)假如应用了System database:

oConn.Open _

"Driver={Microsoft Access Driver (*.mdb)};" 澳门新葡亰集团& _

"Dbq=\somepath\mydb.mdb;" & _

"SystemDB=\somepath\mydb.mdw;", _

"admin", ""

c)ODBC Driver for SQL Server

i)通俗安然模式

oConn.Open "Driver={SQL Server};" & _

"Server=carl2;" & _

"Database=pubs;" & _

"Uid=sa;" & _

"Pwd=;"

ii)应用相信安然模式:

oConn.Open "Driver={SQL Server};" & _

"Server=carl2;" & _

"Database=pubs;" & _

"Uid=;" & _

"Pwd=;"

留意:要应用空缺的Uid和Pwd

d)ODBC Driver for Oracle

i)应用现有的Oracle ODBC Driver from Microsoft:

oConn.Open _

"Driver={Microsoft ODBC for Oracle};" & _

"Server=OracleServer.world;" & _

"Uid=demo;" & _

"Pwd=demo;"

ii)应用老版本的Oracle ODBC Driver from Mic澳门新葡亰集团rosoft:

oConn.Open _

"Driver={Microsoft ODBC Driver for Oracle};" & _

"ConnectString=OracleServer.world;" & _

"Uid=demo;" & _

"Pwd=demo;"

IIII)应用微软的OLE DB Data Link Connections要领Data Link File (UDL)

a)应用绝对路径

oConn.Open "File Name=\somepath\pubs.udl;"

b)应用相对路径

oConn.Open "File Name=pubs.udl;"

V)OLE DB Provider Connections要领

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)通俗安然模式:

oConn.Open _

"Provider=Microsoft.Jet.OLEDB.4.0;" & _

"Data Source=\somepath\mydb.mdb;" & _

"User Id=admin;" & _

"Password=;"

ii)假如应用了System database:

oConn.Open _

"Provider=Microsoft.Jet.OLEDB.4.0;" & _

"Data Source=\somepath\mydb.mdb;" & _

"Jet OLEDB:System Database=system.mdw;", _

"admin", ""

留意:当应用OLE DB Provider4.0版本是,必要把MDB和MDW文件转换成4.0的数据库款式

iii)假如MDB必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=\som澳门新葡亰集团epath\expenses.xls;" & _

"Extended Properties=""Excel 8.0;HDR=Yes;"";"

留意: "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)通俗安然模式:

oConn.Open "Provider=sqloledb;" & _

"Network Library=DBMSSOCN;" & _

"Data Source=carl2;" & _

"Initial Catalog=pubs;" & _

"User Id=sa;" & _

"Password=;"

ii)应用相信安然模式:

oConn.Open "Provider=sqloledb;" & _

Network Library=DBMSSOCN;" & _

"Data Source=carl2;" & _

"Initial Catalog=pubs;" & _

"Trusted_Connection=yes;"

留意:"Network Library=DBMSSOCN"声明OLE DB应用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要领(便是我不停在钻研的RDS要领哦,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自定义事务工具

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=;"
