java通过jdbc连接各种数据库，jdbc知识小总结

  1. java 通过jdbc连接各种数据库

    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 );

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

    Class.forName( “org.postgresql.Driver” );

    cn = DriverManager.getConnection( “jdbc:postgresql://MyDbComputerNameOrIP/myDatabaseName”, sUsr, sPwd );

    1. 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 );

    1. 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”)

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

    Class.forName( “net.sourceforge.jtds.jdbc.Driver” );

    cn = DriverManager.getConnection( “jdbc:jtds:sqlserver://MyDbComputerNameOrIP:1433/master”, sUsr, sPwd );

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

    Class.forName( “com.microsoft.jdbc.sqlserver.SQLServerDriver” );

    cn = DriverManager.getConnection( “jdbc:microsoft:sqlserver://MyDbComputerNameOrIP:1433;databaseName=master”, sUsr, sPwd );

    1. 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 );

    补充

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

    JDBC Name: jTDS

    URL: http://jtds.sourceforge.net/

    Version: 0.5.1

    Download URL: http://sourceforge.net/project/showfiles.php?group_id=33291

    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”);

    Postgresql

    JDBC Name: PostgreSQL JDBC

    URL: http://jdbc.postgresql.org/

    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 FilesIBMClient Accessjt400lib

    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”);

    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

    Class.forName( “com.sybase.jdbc.SybDriver” )
    url=”jdbc:sybase:Tds:127.0.0.1:2638/asademo”;

    Class.forName(“interbase.interclient.Driver”);

    //Driver d = new interbase.interclient.Driver (); /* this will also work if you do not want the line above */

    Connection conn = DriverManager.getConnection( url, “sysdba”, “masterkey” );

    HSqlDB

    url: http://hsqldb.sourceforge.net/

  2. jdbc对于自增字段的处理要使用default
