JDBC常用连接写法（包括MySQL、Oracle、Sybase、SQLServer、DB2）

1. MySQL(http: // www.mysql.com)mm.mysql-2.0.2-bin.jar


Class.forName(  " org.gjt.mm.mysql.Driver " );
cn = DriverManager.getConnection(  " jdbc:mysql://MyDbComputerNameOrIP:3306/myDatabaseName ", sUsr, sPwd );

 

2. PostgreSQL(http: // www.de.postgresql.org)pgjdbc2.jar


Class.forName(  " org.postgresql.Driver " );
cn = DriverManager.getConnection(  " jdbc:postgresql://MyDbComputerNameOrIP/myDatabaseName ", sUsr, sPwd );

 

3. Oracle(http: // www.oracle.com/ip/deploy/database/oracle9i/)classes12.zip


Class.forName(  " oracle.jdbc.driver.OracleDriver " );
cn = DriverManager.getConnection(  " jdbc:oracle:thin:@MyDbComputerNameOrIP:1521:ORCL ", sUsr, sPwd );

 

4. Sybase(http: // jtds.sourceforge.net)jconn2.jar


Class.forName(  " com.sybase.jdbc2.jdbc.SybDriver " );
cn = DriverManager.getConnection(  " jdbc:sybase:Tds:MyDbComputerNameOrIP:2638 ", sUsr, sPwd );
// (Default-Username/Password: "dba"/"sql")

 

5. Microsoft SQLServer(http: // jtds.sourceforge.net)


Class.forName(  " net.sourceforge.jtds.jdbc.Driver " );
cn = DriverManager.getConnection(  " jdbc:jtds:sqlserver://MyDbComputerNameOrIP:1433/master ", sUsr, sPwd );

 

6. Microsoft SQLServer(http: // www.microsoft.com)


Class.forName(  " com.microsoft.jdbc.sqlserver.SQLServerDriver " );
cn = DriverManager.getConnection(  " jdbc:microsoft:sqlserver://localhost:1433;databaseName=pubs ", sUsr, sPwd );

 

7. ODBC


Class.forName(  " sun.jdbc.odbc.JdbcOdbcDriver " );
Connection cn = DriverManager.getConnection(  " jdbc:odbc: " + sDsn, sUsr, sPwd );

 

8.DB2(新添加)


Class.forName( " com.ibm.db2.jdbc.net.DB2Driver ");
String url= " jdbc:db2://192.9.200.108:6789/SAMPLE "
cn = DriverManager.getConnection( url, sUsr, sPwd );

 

9.Microsoft SQL Server series ( 6.5,  7.x and  2000) and Sybase  10

语法:
Class.forName( " net.sourceforge.jtds.jdbc.Driver  ");
Connection con = DriverManager.getConnection( " jdbc:jtds:sqlserver://host:port/database ", " user ", " password ");
or
Connection con = DriverManager.getConnection( " jdbc:jtds:sybase://host:port/database ", " user ", " password ");

 

10.Postgresql


JDBC Name: PostgreSQL JDBC

Class.forName( " org.postgresql.Driver "); 
Connection con=DriverManager.getConnection( " jdbc:postgresql://host:port/database ", " user ", " password ");

 

11.IBM AS400主机在用的JDBC语法


有装V4R4以上版本的Client Access Express
可以在C:\Program Files\IBM\Client Access\jt400\lib
找到 driver 档案 jt400.zip，并更改扩展名成为 jt400.jar
语法:
java.sql.DriverManager.registerDriver ( new com.ibm.as400.access.AS400JDBCDriver ());
Class.forName( " com.ibm.as400.access.AS400JDBCConnection ");
con = DriverManager.getConnection( " jdbc:as400://IP ", " user ", " password ");

 

12.informix


Class.forName( " com.informix.jdbc.IfxDriver ").newInstance(); 
String url = 
" jdbc:informix-sqli://123.45.67.89:1533/testDB:INFORMIXSERVER=myserver; 
user=testuser;password=testpassword " ;
Lib：jdbcdrv.zip<br><br>Class.forName(  " com.sybase.jdbc.SybDriver " )

con-str（http）: jdbc:hsqldb:http: // dbsrv
con-str（hsql）: jdbc:hsqldb:hsql: // dbsrv
