Java methods to connect to various databases

This article illustrates how Java can connect to various databases. Share with you for your reference. The details are as follows:

//MySQL :    

    String Driver="com.mysql.jdbc.Driver";   //Driver 

     String URL="jdbc:mysql://localhost:3306/db_name";    // Of the connection URL,db_name Is the database name   

     String Username="username";   //User name 

     String Password="password";   //Password < br / >
     Class.forName(Driver).newInstance();

     Connection con=DriverManager.getConnection(URL,Username,Password);

//Microsoft SQL Server 2.0 driver (the 3-jar one):

     String Driver="com.microsoft.jdbc.sqlserver.SQLServerDriver";   //Method to connect to SQL database 

     String URL="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=db_name";    //db_name Is the database name 

     String Username="username";   //User name 

     String Password="password";   //Password < br / >
     Class.forName(Driver).newInstance();   //Load data to drive 

     Connection con=DriverManager.getConnection(URL,UserName,Password);   //

//Microsoft SQL Server 3.0 drive (1 a jar the ): //  Old purple bamboo is perfect 

     String Driver="com.microsoft.sqlserver.jdbc.SQLServerDriver";   //Method to connect to SQL database 

     String URL="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=db_name";    //db_name Is the database name 

     String Username="username";   //User name 

     String Password="password";   //Password < br / >
     Class.forName(Driver).newInstance();   //Load data to drive 

     Connection con=DriverManager.getConnection(URL,UserName,Password);   //

// Sysbase:

     String Driver="com.sybase.jdbc.SybDriver";   //Driver 

     String URL="jdbc:Sysbase://localhost:5007/db_name";    //db_name Name for data 

     String Username="username";   //User name 

     String Password="password";   //Password < br / >
     Class.forName(Driver).newInstance();   

    Connection con=DriverManager.getConnection(URL,Username,Password);

//Oracle (in thin mode) : < br / >
     String Driver="oracle.jdbc.driver.OracleDriver";   //Method to connect to the database 

     String URL="jdbc:oracle:thin:@loaclhost:1521:orcl";   //Orcl is the SID of the database 

     String Username="username";   //User name 

     String Password="password";   //Password < br / >
     Class.forName(Driver).newInstance();   //Load database driver 

     Connection con=DriverManager.getConnection(URL,Username,Password);   

//PostgreSQL:

     String Driver="org.postgresql.Driver";   //Method to connect to the database 

     String URL="jdbc:postgresql://localhost/db_name";    //db_name Name for data 

     String Username="username";   //User name 

     String Password="password";   //Password < br / >
     Class.forName(Driver).newInstance();   

    Connection con=DriverManager.getConnection(URL,Username,Password);

// DB2 : 

     String Driver="com.ibm.db2.jdbc.app.DB2.Driver";   //Connect to the Provider instance 
 with the DB2 client
     //String Driver="com.ibm.db2.jdbc.net.DB2.Driver";    // Connection does not have DB2 The client's Provider The instance 

     String URL="jdbc:db2://localhost:5000/db_name";    //db_name Name for data 

     String Username="username";   //User name 

     String Password="password";   //Password < br / >
     Class.forName(Driver).newInstance();   

    Connection con=DriverManager.getConnection(URL,Username,Password);

//Informix:

     String Driver="com.informix.jdbc.IfxDriver";   

    String URL="jdbc:Informix-//sqli://localhost:1533/db_name:INFORMIXSER=myserver";    //db_name Name for data 

     String Username="username";   //User name 

     String Password="password";   //Password < br / >
     Class.forName(Driver).newInstance();   

    Connection con=DriverManager.getConnection(URL,Username,Password);

// JDBC-ODBC:

     String Driver="sun.jdbc.odbc.JdbcOdbcDriver";

     String URL="jdbc:odbc:dbsource";   //Dbsource is the name of the data source 

     String Username="username";   //User name 

     String Password="password";   //Password < br / >
     Class.forName(Driver).newInstance();   

    Connection con=DriverManager.getConnection(URL,Username,Password);
