一、MySQL Connector/ODBC 2.50 (MyODBC 2.50)连接方式 

1、本地数据库连接

Driver = {MySQL};Server = localhost; Option = 16834 ; Database = myDataBase; 

2、远程数据连接

Driver = {MySQL};Server = myServerAddress; Option = 131072 ;Stmt = ; Database = myDataBase; User = myUsername;Password = myPassword; 

3、特殊的TCP/IP端口连接
说明：此Driver的默认端口是3306。如果没有在连接字符串中特别指出就是连接MySQL的3306端口。

Driver = {MySQL};Server = myServerAddress;Port = 3306 ; Option = 131072 ;Stmt = ; Database = myDataBase; User = myUsername;Password = myPassword;

二、MySQL Connector/ODBC 3.51 (MyODBC 3.51)连接方式

1、本地数据库连接

Driver = {MySQL ODBC 3.51 Driver};Server = localhost; Database = myDataBase; User = myUsername;Password = myPassword; Option = 3 ; 

2、远程数据连接

Driver = {MySQL ODBC 3.51 Driver};Server = data.domain.com; Database = myDataBase; User = myUsername; Password = myPassword; Option = 3 ;

3、特殊的TCP/IP端口连接
说明：此Driver的默认端口是3306。如果没有在连接字符串中特别指出就是连接MySQL的3306端口。

Driver = {MySQL ODBC 3.51 Driver};Server = data.domain.com;Port = 3306 ; Database = myDataBase; User = myUsername; Password = myPassword; Option = 3 ;

4、特殊字符集的连接

Driver = {MySQL ODBC 3.51 Driver};Server = data.domain.com;charset = UTF8; Database = myDataBase; User = myUsername; Password = myPassword; Option = 3 ;

三、OLE DB, OleDbConnection (.NET)连接方式

1、标准连接

Provider = MySQLProv;Data Source = mydb; User Id = myUsername;Password = myPassword;

四、MySQL Connector/Net (.NET)连接方式

1、标准连接(说明，默认端口是3306。)

Server = myServerAddress; Database = myDataBase;Uid = myUsername;Pwd = myPassword;

2、特殊的TCP/IP端口连接

Server = myServerAddress;Port = 1234 ; Database = myDataBase;Uid = myUsername;Pwd = myPassword;

3、命名管道
说明：端口值为-1，说明用命名管道方式连接。此方式只在Windows下有效，在UNIX下用会被忽略。

Server = myServerAddress;Port =- 1 ; Database = myDataBase;Uid = myUsername;Pwd = myPassword;

4、多服务器连接
用此种方式连接到数据库中，不必担心该使用哪个数据库。

Server = serverAddress1 & serverAddress2 & etc..; Database = myDataBase;Uid = myUsername;Pwd = myPassword;

5、加密选项
这条活动的SSL连接加密所有客户端和服务器商的数据传输。而且服务器要有一个证书。
这个选项从Connector/NET5.0.3版开始出现，以前的版本中则没有此功能。

Server = myServerAddress;Port =- 1 ; Database = myDataBase;Uid = myUsername;Pwd = myPassword;

6、修改默认的命令超时时间
使用这条修改连接的默认命令超时时间。注意：此条不会影响你在单独命令对象上设置的超时时间。
此条只对Connector/NET 5.1.4 及以上的版本有效.

Server = myServerAddress; Database = myDataBase;Uid = myUsername;Pwd = myPassword; default command timeout = 20 ;

7、修改连接偿试时间
使用这条修改在终止重试和接收错误的等待时间(以秒为单位)

Server = myServerAddress; Database = myDataBase;Uid = myUsername;Pwd = myPassword;Connection Timeout = 5 ;

8、Inactivating prepared statements
Use this one to instruct the provider to ignore any command prepare statements and prevent corruption issues with server side prepared statements.
此选项被加入到Connector/NET的5.0.3版和1.0.9版。

Server = myServerAddress; Database = myDataBase;Uid = myUsername;Pwd = myPassword;Ignore Prepare = true;

9、特殊的TCP/IP端口连接
这条语句修改连接的端口。
默认端口是3306。此参数会被Unix忽略。

Server = myServerAddress; Database = myDataBase;Uid = myUsername;Pwd = myPassword;Port = 3306 ;

10、特殊网络协议
这条语句修改用哪种协议进行连接。
如果没有特别说明，"socket"是默认的值。"tcp"是与"socket"相同意义的。"pipe"是使用命名管道连接，"unix"是使用 unix socket连接，"memory"是使用MySQL的共享内存。

Server = myServerAddress; Database = myDataBase;Uid = myUsername;Pwd = myPassword;Protocol = socket;

11、特殊字符集的连接
这个语句指出以使种字符串编码发送到服务器上的查询语句。
注意：查询结果仍然是以反回数据的格式传送。

Server = myServerAddress; Database = myDataBase;Uid = myUsername;Pwd = myPassword;CharSet = UTF8;

12、修改共享内存名
此语句用来修改用来通信的共享内存名称。
说明：此语句只有当连接协议设置为"memory"时才有效。

Server = myServerAddress; Database = myDataBase;Uid = myUsername;Pwd = myPassword;Shared Memory Name = MySQL;

五、MySQLConnection (.NET)连接方式

1、eInfoDesigns.dbProvider

Data Source = myServerAddress; Database = myDataBase; User ID = myUsername;Password = myPassword;Command Logging = false;

六、SevenObjects MySQLClient (.NET)连接方式

1、标准连接

Host = myServerAddress;UserName = myUsername;Password = myPassword; Database = myDataBase; 

七、Core Labs MySQLDirect (.NET)连接方式

1、标准连接

User ID = root;Password = myPassword;Host = localhost;Port = 3306 ; Database = myDataBase; Direct = true;Protocol = TCP;Compress = false;Pooling = true; Min Pool Size = 0 ; Max Pool Size = 100 ;Connection Lifetime = 0 ;

八、MySQLDriverCS (.NET)连接方式

1、标准连接

Location = myServerAddress;Data Source = myDataBase; User ID = myUsername;Password = myPassword;Port = 3306 ;Extended Properties = """";
