A brief analysis of JAVA's commonly used JDBC methods to connect to the database summary

1. JDBC connection to DB2

Copy the code code as follows:

Class.forName("Com.ibm.db2.jdbc.net.DB2Driver");

String url="jdbc:db2://dburl:port/DBname"

cn = DriverManager.getConnection( url, sUsr, sPwd );

Class.forName("Com.ibm.db2.jdbc.net.DB2Driver");

String url="jdbc:db2://dburl:port/DBname"

cn = DriverManager.getConnection( url, sUsr, sPwd );

2. JDBC connection to Microsoft SQLServer (microsoft)

Copy the code code as follows:

Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver" );

cn = DriverManager.getConnection( "jdbc:microsoft:sqlserver://DBServerIP:1433;databaseName=master", sUsr, sPwd );

Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver" );

cn = DriverManager.getConnection( "jdbc:microsoft:sqlserver://DBServerIP:1433;databaseName=master", sUsr, sPwd );

3. JDBC connection to Sybase (jconn2.jar)

Copy the code code as follows:

Class.forName( "com.sybase.jdbc2.jdbc.SybDriver" );

cn = DriverManager.getConnection( "jdbc:sybase:Tds:DBServerIP:2638", sUsr, sPwd );

Class.forName( "com.sybase.jdbc2.jdbc.SybDriver" );

cn = DriverManager.getConnection( "jdbc:sybase:Tds:DBServerIP:2638", sUsr, sPwd );

4. JDBC connection to MySQL (mm.mysql-3.0.2-bin.jar)

Copy the code code as follows:

Class.forName( "org.gjt.mm.mysql.Driver" );

cn = DriverManager.getConnection( "jdbc:mysql://DBServerIP:3306/myDatabaseName", sUsr, sPwd );

Class.forName( "org.gjt.mm.mysql.Driver" );

cn = DriverManager.getConnection( "jdbc:mysql://DBServerIP:3306/myDatabaseName", sUsr, sPwd );

5. JDBC connection to PostgreSQL (pgjdbc2.jar)

Copy the code code as follows:

Class.forName( "org.postgresql.Driver" );

cn = DriverManager.getConnection( "jdbc:postgresql://DBServerIP/myDatabaseName", sUsr, sPwd );

Class.forName( "org.postgresql.Driver" );

cn = DriverManager.getConnection( "jdbc:postgresql://DBServerIP/myDatabaseName", sUsr, sPwd );

6. JDBC connection to Oracle (classes12.jar)

Copy the code code as follows:

Class.forName( "oracle.jdbc.driver.OracleDriver" );

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

Class.forName( "oracle.jdbc.driver.OracleDriver" );

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

7. JDBC connects to ODBC

Copy the code code as follows:

Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver" );

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