ODBC、OLE连接各种数据库的连接字符串

简介

我们在使用数据库的时候，首先需要打开这个数据库。
我们可以找到集中类型的数据库，每个都使用不同的连接方式。
下面列举了一下主要的数据库的连接字符串

A：使用ODBC方式

1:dBASE连接字符串
strConnection = _T("Driver={Microsoft dBASE Driver (*.dbf)};DriverID=277;"
"Dbq=c:\\DatabasePath;");

2:Excel连接字符串

strConnection = _T("Driver={Microsoft Excel Driver (*.xls)};DriverId=790;"
bq=C:\\DatabasePath\\DBSpreadSheet.xls;DefaultDir=c:\\databasepath;");

3：Text连接字符串

strConnection = _T("Driver={Microsoft Text Driver (*.txt; *.csv)};"
"Dbq=C:\\DatabasePath\\;Extensions=asc,csv,tab,txt;");

4:Visual FoxPro连接字符串

strConnection = _T("Driver={Microsoft Visual Foxpro Driver};UID=;"
ourceType=DBC;SourceDB=C:\\DatabasePath\\MyDatabase.dbc;Exclusive=No");

strConnection = _T("Driver={Microsoft Visual Foxpro Driver};UID=;"
"SourceType=DBF;SourceDB=C:\\DatabasePath\\MyDatabase.dbc;Exclusive=No");

5：Access连接字符串

strConnection = _T("Driver={Microsoft Access Driver (*.mdb)};"
"Dbq=c:\\DatabasePath\\dbaccess.mdb;Uid=;Pwd=;");

6：:SQL Server连接字符串

strConnection = _T("Driver={SQL Server};Server=MyServerName;"
"Trusted_Connection=no;"
"Database=MyDatabaseName;Uid=MyUserName;Pwd=MyPassword;");

7:Oracle连接字符串

strConnect = _T("Driver={Microsoft ODBC for Oracle};Server=OracleServer.world;"
"Uid=MyUsername;Pwd=MyPassword;");

8：MySQL连接字符串
strConnect = _T("Driver={MySQL ODBC 3.51 Driver};Server=localhost;"
"Database=MyDatabase;User=MyUserName;Password=MyPassword;Option=4;");

9：SyBase连接字符串
strConnect = _T("Driver={Sybase System 10};Srvr=MyServerName;Uid=MyUsername;"
"Pwd=myPassword;");

10：SqlAnyWhere连接字符串
strConnect = _T("ODBC;Driver=Sybase SQL Anywhere 5.0;"
"DefaultDir=C:\\DatabasePath\;Dbf=C:\\SqlAnyWhere50\\MyDatabase.db;"
"Uid=MyUsername;Pwd=MyPassword;Dsn=\"\";");

B：使用OLE方式

1：SQL Server连接字符串
标准的：strConnect = _T("Provider=sqloledb;Data Source=MyServerName;"
"Initial Catalog=MyDatabaseName;"
"User Id=MyUsername;Password=MyPassword;");

2：MySQL 连接字符串
strConnection = _T("Provider=MySQLProv;Data Source=test");

3：AS400连接字符串
strConnect = _T("Provider=IBMDA400;Data source=myAS400;User Id=myUsername;"
"Password=myPassword;");

4：DB2连接字符串
使用TCPID
strConnect = _T("Provider=DB2OLEDB;Network Transport Library=TCPIP;"
"Network Address=130.120.110.001;"
"Initial Catalog=MyCatalog;Package Collection=MyPackageCollection;"
"Default Schema=MySchema;User ID=MyUsername;Password=MyPassword;");
使用APPC
strConnect = _T("Provider=DB2OLEDB;APPC Local LU Alias=MyLocalLUAlias;"
"APPC Remote LU Alias=MyRemoteLUAlias;Initial Catalog=MyCatalog;"
"Package Collection=MyPackageCollection;Default Schema=MySchema;"
"User ID=MyUsername;Password=MyPassword;");

5:Microsoft Jet连接字符串
标准的：strConnect = _T("Provider=Microsoft.Jet.OLEDB.4.0;"
"Data Source=C:\\DatabasePath\\MmDatabase.mdb;"
"User Id=admin;Password=;");

6：使用OLE连接某一个Excel表
strConnect = _T("Provider=Microsoft.Jet.OLEDB.4.0;"
"Data Source=C:\\DatabasePath\\DBSpreadSheet.xls;"
"Extended Properties=\"\"Excel 8.0;HDR=Yes;\"\";");

注意 HDR=Yes 是第一行是字段，会自动过滤

7：OLAP连接字符串
strConnect = _T("Provider=MSOLAP;Data Source=MyOLAPServerName;"
"Initial Catalog=MyOLAPDatabaseName;");

8：Oracle连接字符串

trConnect = _T("Provider=MSDAORA;Data Source=MyOracleDB;User Id=myUsername;"
"Password=myPassword;");

8：Data Link Connections字符串

strConnection = _T("File Name=c:\\DataBasePath\\DatabaseName.udl;");
