我需要创建一个带有sql Server Management Studio 2005的链接服务器到Access 95数据库,该数据库恰好在数据库级别受密码保护.用户级安全性尚未实现.
我无法将Access数据库转换为更新的版本.它被第三方应用程序使用;因此,不允许以任何方式修改它.
我已经尝试使用Jet 4.0 OLE DB提供程序和ODBC OLE DB提供程序.第三方应用程序创建一个系统DSN(使用正确的数据库密码),但我没有运气使用任何一种方法.
如果我使用标准连接字符串,我认为它看起来像这样：
Provider=Microsoft.Jet.OLEDB.4.0;Data Source='C:\Test.mdb';Jet OLEDB:Database Password=####;
我很确定我需要以某种方式将Jet OLEDB：数据库密码合并到链接服务器设置中,但还没弄清楚如何.
我已经发布了我正在使用的脚本以及下面的相关错误消息.任何帮助是极大的赞赏.如果需要,我会提供更多细节,请问.
谢谢！
方法#1 – 使用Jet 4.0提供程序
当我尝试运行这些语句来创建链接服务器时：
sp_dropserver 'Test','droplogins'; EXEC sp_addlinkedserver @server = N'Test',@provider = N'Microsoft.Jet.OLEDB.4.0',@srvproduct = N'Access DB',@datasrc = N'C:\Test.mdb' GO EXEC sp_addlinkedsrvlogin @rmtsrvname=N'Test',@useself=N'False',@locallogin=NULL,@rmtuser=N'Admin',@rmtpassword='####' GO
测试连接时出现此错误：
TITLE: Microsoft sql Server Management Studio ------------------------------ "The test connection to the linked server Failed." ------------------------------ ADDITIONAL INFORMATION: An exception occurred while executing a Transact-sql statement or batch. (Microsoft.sqlServer.ConnectionInfo) ------------------------------ The OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "Test" reported an error. Authentication Failed. Cannot initialize the data source object of OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "Test". OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "Test" returned message "Cannot start your application. The workgroup information file is missing or opened exclusively by another user.". (Microsoft sql Server,Error: 7399) ------------------------------
方法#2 – 使用ODBC提供程序…
sp_dropserver 'Test',@provider = N'MSDAsql',@srvproduct = N'ODBC',@datasrc = N'Test:DSN' GO EXEC sp_addlinkedsrvlogin @rmtsrvname=N'Test',@rmtpassword='####' GO
我收到此错误：
TITLE: Microsoft sql Server Management Studio ------------------------------ "The test connection to the linked server Failed." ------------------------------ ADDITIONAL INFORMATION: An exception occurred while executing a Transact-sql statement or batch. (Microsoft.sqlServer.ConnectionInfo) ------------------------------ Cannot initialize the data source object of OLE DB provider "MSDAsql" for linked server "Test". OLE DB provider "MSDAsql" for linked server "Test" returned message "[Microsoft][ODBC Driver Manager] Driver's sqlSetConnectAttr Failed".

OLE DB provider "MSDAsql" for linked server "Test" returned message "[Microsoft][ODBC Microsoft Access Driver] Cannot open database '(unknown)'. It may not be a database that your application recognizes,or the file may be corrupt.". (Microsoft sql Server,Error: 7303)
解决方法
经过几个小时的努力解决这个问题,我终于发现不是一个,而是两个解决方案！我正在使用sql Server 2008和Access 2000,但我想解决方案是一样的.
解决方案1：使用OPENDATASOURCE
select * from
OPENDATASOURCE('Microsoft.JET.OLEDB.4.0','Data Source=C:\MyAccessDB.mdb;User ID=Admin;Password=;Jet OLEDB:Database Password=MyDBPassword;')...MyTable
为此,您还需要打开Ad Hoc Distributed Queries选项：
exec sp_configure 'show advanced options',1; RECONFIGURE; exec sp_configure 'Ad Hoc Distributed Queries',1; RECONFIGURE; GO
如您所述,链接服务器似乎不起作用.然而,有一个小问题,使一切顺利;您需要在提供程序字符串中指定数据库密码,例如; PWD = password.
exec sp_addlinkedserver
@server = 'TestLinkServer',@provider = 'Microsoft.Jet.OLEDB.4.0',@srvproduct = 'Access',@datasrc = 'C:\MyAccessDB.mdb',@provstr = ';PWD=MyDBPassword'
exec sp_addlinkedsrvlogin
@rmtsrvname = 'TestLinkServer',@useself = 'FALSE',@locallogin = null,@rmtuser = 'Admin',@rmtpassword = null
走
select * from TestLinkServer...MyTable
