ODBC

MySQL

strConnect = _T("Driver={MySQL ODBC 3.51 Driver};Server=localhost;"
"Database=MyDatabase;User=MyUserName;Password=MyPassword;Option=4;useUnicode=true&characterEncoding=UTF-8");

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=;"
    urceType=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;");
 

 
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;");

Q&A

无法解析的外部符号 __imp___vsnprintf

在 vs2015 工程选项，链接器附加依赖项里面添加 legacy_stdio_definitions.lib 即可。
出现这个问题的原因是 vs2015 默认编译时将许多标准库采用内联方式处理，因而没有可以链接的标准库文件，所以要专门添加标准库文件来链接标准库中的函数。
